、创建个Winform项目。

、在From1上增加一个文本框一个按钮。

、在解决方案中创建一个test.js文件。

test.js代码如下：

function sayHello(str) {

    return "Hello," + str;

}

、进入Form1.cs编码后台代码。

private void button1_Click(object sender, EventArgs e)

        {

            string path = AppDomain.CurrentDomain.BaseDirectory + "test.js";

            string str2 = File.ReadAllText(path);

            string fun = string.Format(@"sayHello('{0}')" ,this.textBox1.Text.Trim());

            string result = ExecuteScript(fun, str2);

            MessageBox.Show(result);

        }

        /// <summary>

        /// 执行JS

        /// </summary>

        /// <param name="sExpression">参数体</param>

        /// <param name="sCode">JavaScript代码的字符串</param>

        /// <returns></returns>

        private string ExecuteScript(string sExpression, string sCode)

        {

            MSScriptControl.ScriptControl scriptControl = new MSScriptControl.ScriptControl();

            scriptControl.UseSafeSubset = true;

            scriptControl.Language = "JScript";

            scriptControl.AddCode(sCode);

            try

            {

                string str = scriptControl.Eval(sExpression).ToString();

                return str;

            }

            catch (Exception ex)

            {

                string str = ex.Message;

            }

            return null;

        }

function callMe(arg1, arg2) {

    return "arg1 is "+arg1+" and arg2 is "+arg2+"!";

}

object[] args = {"argString1", "argString2"};

webBrowser1.Document.InvokeScript("callMe",args);
