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，建一個帶兩個參數(shù)的public方法。

復制代碼代碼如下:

 
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; 
} 
} 

接下來，我們創(chuàng)建一個用戶控件:

復制代碼代碼如下:

 
<%@ 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" /> 

寫銨鈕事件，首先引用namespace using System.Reflection;
有關type.InvokeMember()方法，可以參考msdn:http://msdn.microsoft.com/zh-cn/library/de3dhzwy(v=vs.80).aspx

復制代碼代碼如下:

 
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 }); 
} 
}
