我可以在这里使用MessageBox.Show吗?但是当我尝试使用它时，出现了一个错误

can I use MessageBox.Show here. But when I tried using it gave me an error

推荐答案

否.

MessageBox(如果使用过的话)将显示在服务器上，而不是客户端上.
要在客户端上显示消息框，您需要使用javascript.参见此处:在ASP.NET网页中添加客户端消息框 [

No.

MessageBox (if you used it) would show on the server, not the client.
To display a message box on the client, you need to use javascript. See here: Adding Client-Side Message Boxes in your ASP.NET Web Pages[^]

您可以使用一个Asp.Net按钮以显示如下所示的MessageBox:-

You can use an Asp.Net button to show a MessageBox like this:-

<asp:button ID="Button1" runat="server" Text="Confirm" OnClientClick="return confirm('Are you sure you want to continue?');"/> 

您也可以注册您的服务器端的javascript如下:

You can also register your javascript from server side as follows:

protected void lnk_click(object sender, EventArgs e)
{

      string javaScript ="<script language=JavaScript>\n" +
                   "confirm('Are you sure you want to continue?');" +
                   "</script>";
      Page.RegisterStartupScript("Confirmation", javaScript);
}
