How Can I create an object instance from a string

[Guest]

I would like to create an instance of System.Windows.Form.TextBox
but I just have the name of the objec in a string like that:

string strType = "System.Windows.Form.TextBox";

I tryed myOgject = CreateInstance(Type.GetType(strType))
but it does not work because Type.GetType(strType) rturn null.

Does anybody can help me???

Try this :
using System.Reflection;
//...
//...
string strTypeName = "System.Windows.Form.TextBox";
Object Obj = Activator.CreateInstance(strTypeName)

Hi,

IIRC the string being passed need to have more details about the type being
instantiated, this was the reason I never used it. I have used
AppDomain.CreateInstance and it does work great

The problem could be in that yoy have no assembly with TextBox loaded

use smth like this

string strType = "System.Windows.Forms.TextBox";
Assembly asm = Assembly.LoadWithPartialName("System.Windows.Forms");
Type tp = asm.GetType(strType);
object obj = Activator.CreateInstance(tp);

PS: LoadWithPartialName is depricated in .net 2.0
