How do I dynamically load a control from a DLL

Platform: WinForms| Category: Controls

You use System Reflection to dynamically load a control. If the DLL is named ‘SpecControls.DLL’ and the class you
want is ‘SpecControls.ColorControl’, then use this code.

[C#]
	// load the assembly
	System.Reflection.Assembly assembly = Assembly.LoadFrom('SpecControls.DLL');

	// get the type
	Type t = assembly.GetType('SpecControls.ColorControl');

	// create an instance and add it.
	//
	Control c = (Control)Activator.CreateInstance(t);
	parent.Controls.Add(c);

[VB.NET]
	 ’ load the assembly
	Dim assembly1 As System.Reflection.Assembly = Assembly.LoadFrom('SpecControls.DLL')

	’ get the type
	Dim t As Type = assembly1.GetType('SpecControls.ColorControl')

	’ create an instance and add it.
	’
	Dim c As Control = CType(Activator.CreateInstance(t), Control) 
	parent.Controls.Add(c)
