推荐答案

在你的用户控件上创建一个属性要传递给它的数据的数据类型，并在创建控件时将其填充到页面中。

Create a property on your user control with the datatype of the data you want to pass to it, and populate it in your page on creation of the control.

public class myUserControl : Control
    {
      ...
      public int myIntProperty {get; set;}
      ...
    }

稍后在后面的代码中您可以分配值，例如

Later this in the code behind you can assign the value like

myUserControl cntrl = new myUserControl();
    cntrl.myIntProperty = test.text;

而不是这个你可以通过Markup传递值也像

Instead of this you can pass the value through Markup also like

<uc1:myUserControl ID="uc1" runat="server" myIntProperty="5" />
