本文介绍了解决.NET应用程序中出现的CS0012错误的方法，此错误与未引用System.Data.Entity程序集有关。通过在web.config文件中正确添加程序集引用，可以避免编译时遇到此类问题。

说明: 在编译向该请求提供服务所需资源的过程中出现错误。请检查下列特定错误详细信息并适当地修改源代码。           

编译器错误消息: CS0012: 类型“System.Data.Objects.DataClasses.EntityObject”在未被引用的程序集中定义。必须添加对程序集“System.Data.Entity, Version=4.0.0.0, Culture=neutral,  PublicKeyToken=b77a5c561934e089”的引用。

出现这个错误的原因是Web.config配置文件的原因。

解决办法：

在web.config中的<system.web>节点下的<system.web>节点下的<assemblies>中添加：

<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

Chapter 3: Introduction to Objects and Classes The Object-Oriented Paradigm Course: CS101: Java Language Programming Instructor: [Instructor Name] Date: September 22, 2025 Practical Session Objective Lab Goal: Refactor to an Object-Oriented Design Our goal is to stop using loose, primitive variables to represent our contact and instead create a proper Contact object. This is a foundational step in building professional software. Prerequisites: Java JDK 11 or higher installed. An IDE like IntelliJ IDEA or VS Code ready. Your MyContactManager project from the last lab. Final Result Preview: The console output will look exactly the same as before, but the underlying code structure will be vastly superior, organized, and ready for future expansion. Step 1: Create the Contact Class Blueprint First, we need to create the blueprint for what a "Contact" is in our application. 1. Goal: Create a new Contact.java file and define the state of a contact. 2. Instructions: 1. In your IDE's project explorer, right-click on your source folder and create a new Java Class. 2. Name the file Contact . This will generate Contact.java . 3. Inside the Contact class, declare the instance variables that every contact will have. These are the same variables that are currently cluttering up your main method. 3. Code Block (for Contact.java ): --- Contact Details --- Name: John Doe Age: 42 Phone: 555-1234 1 2 3 44. Expected Result: You now have two files in your project: MyContactManager.java and Contact.java . The code should compile without errors. Step 2: Instantiate a Contact Object Now that we have the blueprint, let's go back to our main application and create an actual contact from it. 1. Goal: In MyContactManager.java , replace the old primitive variables with a single Contact object. 2. Instructions: 1. Open MyContactManager.java . 2. Delete all the old variable declarations for the contact ( String firstName = "Jane"; , int age = 32; , etc.). 3. In their place, declare and instantiate a new Contact object. 3. Code Block (in main method of MyContactManager.java ): 4. Expected Result: Your main method is now much cleaner. Your code will no longer compile because the parts that used the old variables are now broken. This is good! We'll fix it next. Step 3: Set the Object's State Our contact1 object exists, but its instance variables are all empty ( null or 0 ). Let's fill them with data using dot notation. 1. Goal: Assign values to the instance variables of our new contact1 object. public class Contact { // Instance variables to hold the state of a single contact String firstName; String lastName; int age; String phoneNumber; boolean isFriend; } 1 2 3 4 5 6 7 8 public static void main(String[] args) { // Delete the old variables: // String firstName = "Jane"; (DELETE) // String lastName = "Doe"; (DELETE) // int age = 32; (DELETE) // ...and so on. // Create an object from our blueprint Contact contact1 = new Contact(); // Now we have a single variable, 'contact1', that holds all // the information about our contact. } 1 2 3 4 5 6 7 8 9 10 11 12 132. Instructions: 1. After the line Contact contact1 = new Contact(); , use the dot operator to access each instance variable and assign it a value. 3. Code Block (in main method of MyContactManager.java ): 4. Expected Result: The contact1 object in memory now holds all the data for John Doe. The code still won't compile because the System.out.println statements are broken. Step 4: Get the Object's State Finally, let's fix our print statements to read the data back from the object, again using dot notation. 1. Goal: Update the System.out.println statements to use the object's fields. 2. Instructions: 1. Find your old println statements that are showing compile errors. 2. Prefix each old variable name with contact1. to tell Java to get the value from the object. 3. Code Block (in main method of MyContactManager.java ): 4. Expected Result: All compile errors should now be gone! Your application is fully refactored. // ... after creating the contact object Contact contact1 = new Contact(); // Use dot notation to set the object's state contact1.firstName = "John"; contact1.lastName = "Doe"; contact1.age = 42; contact1.phoneNumber = "555-1234"; contact1.isFriend = false; 1 2 3 4 5 6 7 8 9 // ... after setting the object's state System.out.println("\n--- Contact Details ---"); // OLD: System.out.println("Name: " + firstName + " " + lastName); // NEW: System.out.println("Name: " + contact1.firstName + " " + contact1.lastName); // OLD: System.out.println("Age: " + age); // NEW: System.out.println("Age: " + contact1.age); // OLD: System.out.println("Phone: " + phoneNumber); // NEW: System.out.println("Phone: " + contact1.phoneNumber); 1 2 3 4 5 6 7 8 9 10 11 12 13 14Final Code and Verification Let's look at the final, refactored MyContactManager.java and verify that it works. 1. Goal: Run the application and confirm the output is correct. 2. Code Block (Complete MyContactManager.java ): 3. Expected Output: Success! The output is the same, but our code structure is infinitely better. Optional Challenge Task For Those Who Finish Early... 🚀 If you've completed the refactoring, this challenge will solidify your understanding of objects. Challenge: Create a Second, Independent Object 1. In your main method, create a second Contact object called contact2 . 2. Set the state for contact2 with completely different data (e.g., "Jane Smith", age 35, etc.). 3. Add println statements to display the details for contact2 after displaying the details for contact1 . public class MyContactManager { public static void main(String[] args) { // 1. Create an object (an instance) from the Contact class blueprint Contact contact1 = new Contact(); // 2. Set the state of the object using dot notation contact1.firstName = "John"; contact1.lastName = "Doe"; contact1.age = 42; contact1.phoneNumber = "555-1234"; contact1.isFriend = false; // 3. Get the state of the object using dot notation System.out.println("--- Contact Details ---"); System.out.println("Name: " + contact1.firstName + " " + contact1.lastName); System.out.println("Age: " + contact1.age); System.out.println("Phone: " + contact1.phoneNumber); } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 --- Contact Details --- Name: John Doe Age: 42 Phone: 555-1234 1 2 3 4This will prove that contact1 and contact2 are two separate objects in memory, each with its own independent state, even though they were built from the same class blueprint. Q&A and Wrap-up Questions? Today's Most Important Lesson Organizing code into classes that model real-world concepts is the single most powerful strategy for managing complexity in software. We took a chaotic collection of variables and transformed it into a clean, intuitive structure. A Contact is now a "thing" in our program, just as it is in the real world. This is the foundation upon which all large-scale, professional applications are built. What's Next? Up Next: Protecting Our Objects Right now, our code has a major flaw. Anyone using our Contact class can do this: contact1.age = -99; contact1.phoneNumber = "this is not a phone number"; This is dangerous and leads to bugs! An object should be in control of its own data. Next Lecture: Chapter 4: Deeper Dive into Classes - Encapsulation We'll learn about encapsulation, a core OOP principle for data hiding and protection. We'll introduce private variables and public getter/setter methods to create robust, bug-resistant objects. 以上问题的答案是什么

这些方法和属性共同构成了一个强大的接口,用于在C#中操作Excel形状,特别是SmartArt对象。它们展示了如何与Excel的COM对象交互,修改形状的各种属性,如颜色、线条粗细和布局。这个类的设计考虑到了易用性和灵活性,允许开发者精确控制Excel中的图形元素。这个方法重写了Object类的ToString方法,提供了ExShape对象的自定义字符串表示。当然,我会为这段代码添加详细的中文注释,以便于您的学习和博客发表。这个方法设置形状轮廓的颜色。它同时设置线条的前景色和背景色,以确保一致的颜色效果。
