大家好.我正在使用ASP.NET和C#创建网页.

In the control, I need a couple public strings for be readed by the .aspx page, but I can''t create them, the .aspx don''t show me the strings of the control.

推荐答案

我只是尝试了您在上面描述的内容而已，并且有效.我制作了一个带有公共字符串的用户控件.

Hi,

I just tried what you are describing above and it works. I made a user control that has a public string.

using System;

namespace WebApplication1
{
    public partial class WebUserControl1 : System.Web.UI.UserControl
    {
        public string myString = "myString";  // <-- there it is..

        protected void Page_Load(object sender, EventArgs e)
        {
        }
    }
}

将控件包含在.aspx页中.

Included the control in an .aspx page.

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"

    CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>

<!--  1.  -->
<%@ Register TagPrefix="test" TagName="MyControl" Src="~/WebUserControl1.ascx" %>

<asp:content id="HeaderContent" runat="server" contentplaceholderid="HeadContent" xmlns:asp="#unknown">
</asp:content>
<asp:content id="BodyContent" runat="server" contentplaceholderid="MainContent" xmlns:asp="#unknown">
    <!--  2.  -->
    <test:mycontrol id="MyControl" runat="server"></test:mycontrol>

    <asp:label id="Label1" runat="server" text="Label"></asp:label>
</asp:content>

并在上方设置标签控件以显示公共字符串中的内容.

And set the label control above to show what is in the public string.

using System;

namespace WebApplication1
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Label1.Text = MyControl.myString;
        }
    }
}

可以按预期工作..还是我把您的问题弄错了?

干杯！

Works as expected.. or did I get your question wrong?

Cheers!
