C# WinForm程序执行JS代码的多种方法

ScriptControlClass sc = new ScriptControlClass(); //申明变量
sc.UseSafeSubset = true; //允许执行不安全的代码
sc.Language = "JavaScript"; //表示需要解析的语言为JavaScript
sc.AddCode(Properties.Resources.GetTimes); // Properties.Resources 资源文件
string str = sc.Run("time", new object[] { "time()" }).ToString();  //第一个参数为要执行的方法名，第二个参数为方法体的传入参数，特别注意的是当JS方法中没有传入参数时，这时传递的为该方法名称，不填写的话会抛异常。然后将JS方法执行后的返回结果存储在变量str中

using System;
using MSScriptControl;
using System.Text;

//导入js文件，导入js 方法字符串，然后执行js方法。 通过msscript.ocx控件执行JS脚本 ,先引用  Interop.MSScriptControl.dll
//官网下载： 然后  引用 xxx.ocx就行了  http://www.microsoft.com/downloads/details.aspx?displaylang=zh-cn&FamilyID=D05FCF37-4D9F-4769-9442-0BCEEF907033
