C#动态编译并执行代码

先来张运行时截图：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Microsoft.CSharp;
using System.CodeDom.Compiler;
using System.Reflection;

namespace CSharpDynamicCode
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void btnRun_Click(object sender, EventArgs e)
{
run();
}

void run()
{
CSharpCodeProvider objCSharpCodePrivoder = new CSharpCodeProvider();
ICodeCompiler objICodeCompiler = objCSharpCodePrivoder.CreateCompiler();

CompilerParameters objCompilerParameters = new CompilerParameters();

//添加需要引用的dll
objCompilerParameters.ReferencedAssemblies.Add("System.dll");
objCompilerParameters.ReferencedAssemblies.Add("System.Windows.Forms.dll");

//是否生成可执行文件
objCompilerParameters.GenerateExecutable = false;

//是否生成在内存中
objCompilerParameters.GenerateInMemory = true;

//编译代码
CompilerResults cr = objICodeCompiler.CompileAssemblyFromSource(objCompilerParameters, txtCode.Text);

if (cr.Errors.HasErrors)
{
var msg = string.Join(Environment.NewLine, cr.Errors.Cast<CompilerError>().Select(err => err.ErrorText));
MessageBox.Show(msg, "编译错误");
}
else
{
Assembly objAssembly = cr.CompiledAssembly;
object objHelloWorld = objAssembly.CreateInstance("Test");
MethodInfo objMI = objHelloWorld.GetType().GetMethod("Hello");
objMI.Invoke(objHelloWorld, null);
}
}

private void Form1_Load(object sender, EventArgs e)
{

}
}
}
