Method of dynamically loading custom controls by asp.net

This article shows an example of how asp.net dynamically loads custom controls.Share it for your reference.The implementation is as follows:

//usercontrol.IndexOper For custom controls 

usercontrol.IndexOper uc=(usercontrol.IndexOper)Page.LoadControl(" Custom Control Path ");

uc.ID = "uc";  // Define Only 1 Indication 

//OperContent by PlaceHolder control 

OperContent.Controls.Add(uc);

I hope that the description in this paper will be helpful to everyone's C#program design.
