WinForm中执行JS代码（多种方法）

ScriptControlClass sc &＃61; new ScriptControlClass(); //申明变量
sc.UseSafeSubset &＃61; true; //允许执行不安全的代码
sc.Language &＃61; "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 &＃61; sc.Run("time", new object[] { "time()" }).ToString(); //第一个参数为要执行的方法名&＃xff0c;第二个参数为方法体的传入参数&＃xff0c;特别注意的是当JS方法中没有传入参数时&＃xff0c;这时传递的为该方法名称&＃xff0c;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&＃xff0c;导入js 方法字符串&＃xff0c;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&＃xff1a; 然后 引用 xxx.ocx就行了 http://www.microsoft.com/downloads/details.aspx?displaylang&＃61;zh-cn&FamilyID&＃61;D05FCF37-4D9F-4769-9442-0BCEEF907033
