要利用.NET语言(例如:c# vb.net)开发自己的脚本语言必须实现2步:1.能够动态编译.NET 源代码2.动态调用.NET组件
首先我们介绍下动态条用.NET组件1.新建1个工程作为组件接口DynamicInterface创建新的类:using System;
namespace DynamicInterface{ public interface IDynamic { string getString(); }}
2.新建1个工程作为需要动态调用的组件DynamicClass引用DynamicInterface创建新的类:using System;
namespace DynamicCls{ public class DynamicClass:DynamicInterface.IDynamic //实现接口 { public DynamicClass() { } #region IDynamic 成员
public string getString() { // TODO: 添加 DynamicClass.getString 实现 return "Hello World Huhong"; }
#endregion }
3.新建1个工程来动态调用DynamicClassusing System;using System.Reflection;
using System.Threading;
namespace dynamicreference{ class DynamicReference { ///

/// 应用程序的主入口点。 ///

[STAThread] static void Main(string[] args) { string dllfilename=@"C:\DynamicClass.dll"; Thread.GetDomain().AssemblyLoad+=new AssemblyLoadEventHandler(DynamicReference_AssemblyLoad); Thread.GetDomain().AssemblyResolve+=new ResolveEventHandler(DynamicReference_AssemblyResolve); Assembly asm=System.Reflection.Assembly.LoadFile(dllfilename); Type type=asm.GetType("DynamicCls.DynamicClass",true); Object oh=Activator.CreateInstance(type); MethodInfo mi = type.GetMethod("getString"); Console.WriteLine(mi.Invoke(oh,null).ToString()); //利用反射机制运行 DynamicInterface.IDynamic id=(DynamicInterface.IDynamic)oh; //利用接口运行 Console.WriteLine(id.getString()); }

private static void DynamicReference_AssemblyLoad(object sender, AssemblyLoadEventArgs args) { Console.WriteLine("加载1个组件:"+args.LoadedAssembly.FullName ); }
private static Assembly DynamicReference_AssemblyResolve(object sender, ResolveEventArgs args) { Console.WriteLine("组件解析失败!"); return null; } }}
未完待续....
