C#动态编译并执行字符串样例

本文实例为大家分享了Android九宫格图片展示的具体代码，供大家参考，具体内容如下

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

class Program
{
public static void Main()
{
 // The C# code to execute
 string code = "using System; " +
     "using System.IO; " +
     "public class MyClass{ " +
     " public static void PrintConsole(string message){ " +
     "  Console.WriteLine(message); " +
     " } " +
     "} ";

// Compiler and CompilerParameters
 CSharpCodeProvider codeProvider = new CSharpCodeProvider();
 CompilerParameters compParameters = new CompilerParameters();

// Compile the code
 CompilerResults res = codeProvider.CompileAssemblyFromSource(compParameters, code);

// Create a new instance of the class 'MyClass'// 有命名空间的，需要命名空间.类名
 object myClass = res.CompiledAssembly.CreateInstance("MyClass");

// Call the method 'PrintConsole' with the parameter 'Hello World'
 // "Hello World" will be written in console
 myClass.GetType().GetMethod("PrintConsole").Invoke(myClass, new object[] {"Hello World" });

Console.Read();
}
}
