Database的Connection String编写方法

 在做Database项目开发的时候，首先应该解决数据库连接的问题，这里最关键的是Connection String的填写，下面是收集的help：

The hardest part of this procedure for most people is getting the ConnectionString to work.

For help, see these links, the "SqlConnection (.NET)" sections

Another thing you might try to get the connection string right is the following:

1. Create a new blank file and name it test.udl.

2. Double click on it, and a "Data Link Properties" dialog should appear.

3. On "Providers" tab, select "Microsoft OLE DB Provider for SQL Server" or "SQL Native Client"

4. On "Connections" tab, try various settings and use the the "Test Connection" button to test them. Click "Ok" when it works.

5. Open the test.udl file in Notepad and copy the line that starts with "Provider=" into your Web.config "ConnectionString" value, BUT delete the little part that says "Provider=SQLNCLI.1;"
