Question

I have a method in my user control:

public string ControleIdContainer()
{
   string abc = "Hello";
   return abc;
}

Now I want to call this method on my Page using reflection. I have tried this but it is not working:

DirectoryInfo dirInfo = new DirectoryInfo(Server.MapPath("~/UserControls"));
FileInfo[] controlsInfo = dirInfo.GetFiles("*.ascx");
foreach (var item in controlsInfo)
{
    var customControl = LoadControl(string.Format("~/UserControls/{0}", item));
    var controlType = customControl.GetType();
    var controlClientScript = controlType.GetMethod("ControleIdContainer").Invoke(null,null);
}

Answer 1

The first parameter of MethodInfo.Invoke is the instance on which you want to invoke the method. Pass customControl as the first parameter instead of null and it should work.
