C#动态编译运行代码串

代码

CSharpCodeProvider CSharp  =   new  CSharpCodeProvider();

String[] dll  =  {  " System.dll " ,  " System.Windows.Forms.dll "  };

CompilerParameters 编译参数  =   new  CompilerParameters(dll);

编译参数.GenerateExecutable  =   false ;

编译参数.GenerateInMemory  =   true ;

string  代码串  =  
     " class wxd " +
     " { " +
         " public string  setText(System.Windows.Forms.Control ct) " +
         " { " +         
             " ct.Text = \ " 按钮提示文字被我修改了\ " ; " +

             " System.Windows.Forms.MessageBox.Show(\ " wxwinter\ " ); " +

             " return \ " ok\ " ; " +
         " } " +
     " } " ;

CompilerResults 结果  =  CSharp.CompileAssemblyFromSource(编译参数, 代码串);

Assembly 程序集  =  结果.CompiledAssembly;

object  动态对象  =  程序集.CreateInstance( " wxd " );

MethodInfo 方法  =  动态对象.GetType().GetMethod( " setText " );

object [] 参数  =  {  this .button1 };

object  s  =  方法.Invoke(动态对象, 参数);

System.Console.WriteLine(s);

 注：

C/S环境下dll位置以当前编译路径，一般直接写“XXX.dll”即可。
B/S环境下引用的非系统dll位置需要指定绝对路径，比如：String[] dll = { "d:\SqlDataAccess.dll" };
