C#执行执行Javascript代码的几种方法总结代码的几种方法总结
一、开源项目一、开源项目 Javascript .NET
地址： http://javascriptdotnet.codeplex.com/ 它是Google Chrome V8引擎在.NET上的封装，功能完善，性能相对较高，推荐
使用! (缺点就是asp.net web应用上，好象会报错)
示例代码：
代码如下:
using Noesis.Javascript;
using System;
using System.Collections.Generic;
namespace JsCSharp
{
class Program
{
static void Main(string[] args)
{
using (JavascriptContext ctx = new JavascriptContext())
{
var i = ctx.Run(“1+2”);
Console.WriteLine(i);//3
ctx.Run(“var d = new Date(2013,9-1,2,20,30,15)”);
var d = ctx.GetParameter(“d”);
Console.WriteLine(d);//2013/9/2 20:30:15
var j = ctx.Run(“function add(x,y){return x+y;};add(5,10);”);
Console.WriteLine(j);//15
ctx.Run(“var obj = {};obj.name=’jimmy’;obj.sex=’Male’;obj.name=’杨俊明'”);
var obj = ctx.GetParameter(“obj”) as Dictionary<string, object>;
foreach (var key in obj.Keys)
{
Console.WriteLine(string.Format(“{0}:{1}”, key, obj[key]));
//name:杨俊明
//sex:Male
}
var jsonArr = ctx.Run(“[{Airport:’PEK’,Name:’北京首都机场’},{Airport:’XIY’,Name:’西安咸阳机场’}]”) as Array;
foreach (var item in jsonArr)
{
var json = item as Dictionary<string, object>;
foreach (var key in json.Keys)
{
Console.WriteLine(string.Format(“{0}:{1}”, key, json[key]));
//Airport:PEK
//Name:北京首都机场
//Airport:XIY
//Name:西安咸阳机场
}
}
ctx.SetParameter(“x”, 7);
ctx.Run(“function add(x,y){return x+y;}; function sub(x,y){return x-y;};k = add(2,x);var t = sub(9,1);”);
var k = ctx.GetParameter(“k”);
Console.WriteLine(k);//9
var t = ctx.GetParameter(“t”);
Console.WriteLine(t);//8
Console.Read();
}
}
}
}
部署时要注意，msvcp100.dll、msvcr100.dll这二个文件，要复制到bin目录下
