如何使用 ASP.NET 中的参数呈现 UserControl

How to render UserControl with parameters in ASP.NET

我使用以下代码来渲染 UserControl

//render control to string
StringBuilder b = new StringBuilder();
HtmlTextWriter h = new HtmlTextWriter(new StringWriter(b));
this.LoadControl("~/path_to_control.ascx").RenderControl(h);
string controlAsString = b.ToString();

但我想传递给 UserControl 一些 参数 因此它应该在渲染之前获取数据并更新其属性 .

怎么做到的? 谢谢!

如回答here

Just load the control using the path of the .ascx file, cast to proper type and set the properties one by one:

MyControl myControl = (MyControl )Page.LoadControl("~/path_to_control.ascx");
myControl.Param1= 1;
myControl.Param2= 2;
myControl.RenderControl(h)

或:

Page.LoadControl(typeof(MyControl), new object[] {1, 2}).RenderControl(h);
