**C\#窗体和jsp通信**  
*通过WebBrowser控件将jsp引入窗体程序*

*  配置方法：
 *  窗体程序

namespace B_Test
    {
    
    
        //配置1：写在namespace下，设置Com对外可访问
        [System.Runtime.InteropServices.ComVisible(true)]
        public partial class Form1 : Form
        {}
    }

public Form1()
            {
                InitializeComponent();
                // 配置2：将当前类设置为可由脚本访问
                webBrowser1.ObjectForScripting = this;
            }

//配置3：通信所用的函数，被外部js调用的方法
            public void MyMessageBox(string message)
            {
                //MessageBox.Show(message);
                //jsp调用C#，C#调用自己的发送函数来返回数据
                SendMessage();
            }
    
            private void SendMessage()
            {
                // 调用JavaScript的messageBox方法，并传入参数
                object[] objects = new object[1];
                
                String a1 = AI_V1.Text;
                String a2 = AI_V2.Text;
                String a3 = AI_V3.Text;
                String a4 = AI_V4.Text;
                String a5 = AI_V5.Text;
                String a6 = AI_V6.Text;
                String a7 = AI_V7.Text;
                String a8 = AI_V8.Text;
                String jicha = JiCha_V.Text;
                String message = a1 + ";" + a2 + ";" + a3 + ";" + a4 + ";" + a5 + ";" + a6 + ";" + a7 + ";" + a8 + ";" + jicha;
                objects[0] = message;
                webBrowser1.Document.InvokeScript("GetMessage", objects);
            }

*  效果如图，AI1-8的数据可以随意设置
