C#原码动态编译功能实现之方法二~

using Microsoft.CSharp;
using System.CodeDom.Compiler;

 

   CSharpCodeProvider _SCP = new CSharpCodeProvider();
   CompilerParameters _CP = new CompilerParameters();

   _CP.GenerateExecutable = false;
   _CP.MainClass = "CodeCompile.RunExpression";

   _CP.OutputAssembly = "RunExpression.dll";

   _CP.IncludeDebugInformation = true;

   _CP.ReferencedAssemblies.Add( "System.dll" );

   _CP.GenerateInMemory = false;

   _CP.WarningLevel = 3;

   _CP.TreatWarningsAsErrors = false;
   
   _CP.CompilerOptions = "/optimize";
   _CP.TempFiles = new TempFileCollection("..", true);

   _SCP.CreateCompiler().CompileAssemblyFromSource(_CP,this.txtCodeContent.Text);

 

//注：this.txtCodeContent.Text即为原代码内容，我的测试原码如下：

using System;
using System.IO;

namespace CodeCompile
{
 ///

 /// RunExpression 的摘要说明。
 ///

 public class RunExpression
 {
  public RunExpression()
  {
   //
   // TODO: 在此处添加构造函数逻辑
   //
  }

  public void Run()
  {
   int i = 0;
   int j = 1;

   int m = i + j;

   System.IO.StreamWriter _FS = new System.IO.StreamWriter(@"E:/1.txt",true);
   _FS.Write(System.DateTime.Now.ToString("yyyy-MM-dd mm:ss"));
   _FS.Close();
   
  }
 }
}
