推荐答案

如果你想动态加载那么你应该使用 LoadControl

If you want to load dynamically then you should use LoadControl

var c = this.LoadControl("~/AddressControl.ascx");
this.myPanel.Controls.Add(c);

如果您不想动态加载它，那么您只需要将标记中的控件指定为其他用户控件:

If you do not want to load it dynamically, then you just need to specify the control in your markup as nay other user control:

<AddressControl runat="server" ID="myControl" />

您的情况的问题是您实际上需要对 Web 应用程序下或虚拟目录下的 ASCX 文件的引用.

The problem in your case is that you actually need a reference to the ASCX file under your web application or under a virtual directory.

您必须将 ASCX 文件复制到您的应用程序中，您可以通过配置构建后操作来轻松完成该步骤

You would have to copy your ASCX file to your application, you can do that step easy by configuring the post-build actions

看看下面的文章，它详细描述了如何完成这个过程:

Take a look at the following article which describes in detail how to accomplish this process:

这就像一种解决方法，因为用户控件不是为跨项目共享而设计的，适合您情况的最佳控件称为服务器控件，它们专为此目的而设计

This is like a workaround, because user controls are not designed to be shared across projects, the best control that would fit your situation are called server controls, they are designed for this purpose
