    protected void btn_Insert_Click(object sender, EventArgs e)

    }
}

当我运行时，它会在数据库中插入一个空白数据

我不知道怎么解决它

请任何人帮助我

使用webmethod，然后使用它

添加名称空间

using System.Web.Services;

像这样改变你的方法

[WebMethod]
public static Boolean InsertMethod(string Name, string Email)

移除

<asp:Button ID="btn_Insert" runat="server" Text="INSERT" />

并从.CS页面中删除单击事件然后它就开始工作了
