ASP.Net dynamic code generation

ASP.Net supports dynamic code generation and compilation. Sometimes, you just need a quick and dirty solution. This is one such solution. It writes out a control script, loads it and then deletes the file.

string dynamicControlUrl = “~/” + System.Guid.NewGuid().ToString() + “.ascx”;
string dynamicControlPath = Server.MapPath(dynamicControlUrl);
TextWriter tw = new StreamWriter(dynamicControlPath);
tw.WriteLine(“<%@ Control language=\"c#\" %>“);
tw.WriteLine(““);
tw.Flush();
tw.Close();
Control dynamicControl = Page.LoadControl(dynamicControlUrl);
Page.Controls.AddAt(0, dynamicControl);
dynamicControl = null;
File.Delete(dynamicControlPath);
