<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Src="InsusUC.ascx" TagName="InsusUC" TagPrefix="uc1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

Hi, You input infor as below:<br />
first textbox value:
<asp:Label ID="LabelshowFirstValue" runat="server" Text="" ForeColor="Red"></asp:Label><br />
Second textbox value:
<asp:Label ID="LabelshowLastValue" runat="server" Text="" ForeColor="Red" ></asp:Label>
</div>
</form>
</body>
</html>
Default.aspx.cs，建一个带两个参数的public方法。
代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
public void ReadUCMessage(string value1, string value2)
{
this.LabelshowFirstValue.Text = value1;
this.LabelshowLastValue.Text = value2;
}
}
接下来，我们创建一个用户控件:
代码如下:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="InsusUC.ascx.cs" Inherits="InsusUC" %>
First Name <asp:TextBox ID="TextboxFirstName" runat="server"></asp:TextBox><br />
Last Name <asp:TextBox ID="TextboxLastName" runat="server"></asp:TextBox><br />
<asp:Button ID="ButtonTransmit" runat="server" Text="Transmit" OnClick="ButtonTransmit_Click" />
写铵钮事件，首先引用namespace using System.Reflection;
有关type.InvokeMember()方法，可以参考msdn:http://msdn.microsoft.com/zh-cn/library/de3dhzwy(v=vs.80).aspx
代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Reflection;
public partial class InsusUC : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void ButtonTransmit_Click(object sender, EventArgs e)
{
string v1 = this.TextboxFirstName.Text.Trim();
string v2 = this.TextboxLastName.Text.Trim();
this.Page.GetType().InvokeMember("ReadUCMessage", BindingFlags.InvokeMethod, null, this.Page, new object[] { v1,v2 });
}
}
