C#动态编译

//第一步：添加引用
using System.Reflection; 
using Microsoft.CSharp; 
using System.CodeDom.Compiler;
//第二步：创建需要编译的代码
string MyCodeString=@" 
public class MyTest
{
    public static string GetTestString()
    {
        string MyStr = ""This is a Dynamic Compiler Demo!"";
        return MyStr; 
    } 
}";
//第三步：实现动态编译
CompilerParameters compilerParams = new CompilerParameters(); 
///编译器选项设置
compilerParams.CompilerOptions = "/target:library /optimize"; 
///编译时在内存输出
compilerParams.GenerateInMemory = true; 
///生成调试信息
compilerParams.IncludeDebugInformation = false; 
///添加相关的引用
compilerParams.ReferencedAssemblies.Add("mscorlib.dll"); 
compilerParams.ReferencedAssemblies.Add("System.dll");
ICodeCompiler compiler = new CSharpCodeProvider().CreateCompiler(); 
///编译
CompilerResults results = compiler.CompileAssemblyFromSource(compilerParams,MyCodeString);
//第四步：输出编译结果
///创建程序集
Assembly asm = results.CompiledAssembly; 
///获取编译后的类型
object objMyTestClass = asm.CreateInstance("MyTest");
Type MyTestClassType=objMyTestClass.GetType(); 
///输出结果
Console.WriteLine(MyTestClassType.GetMethod("GetTestString").Invoke(objMyTestClass,null)); 
Console.ReadLine();
//至此，一个简单的动态编译程序就完了，我们看到输出的结果为：
This is a Dynamic Compiler Demo!
