Form窗体后台代码：Form2.cs
namespace WindowsFormsApp
{
//申名托管类型，对com是可见的
[System.Runtime.InteropServices.ComVisible(true)]
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
private void button2_Click(object sender, EventArgs e)
{
this.wbWeb.Navigate(string.Format("javascript:getWinFormValue('{0}');void(0);", this.textBox1.Text));
}
//前台js调用的方法
public void Call(string WebFormValue)
{
this.label1.Text = WebFormValue;
}
private void Form2_Load(object sender, EventArgs e)
{
//此窗体可以通过wbweb控件里面的脚本进行访问
wbWeb.ObjectForScripting = this;
}
}
}
此方法要比前文的 使用webservice实现要简便性能要好！
