field is not a TextBox--field is a FieldInfo instance, which, if you look up
the inheritance hierarchy, has no inheritance relationship to TextBox
whatsoever.
Don't confuse the representation of the reflective type with the type
itself.

Subject: [ADVANCED-DOTNET] InvalidCastException when using Reflection
> Hi all,
>
> I have strange problem with .NET Reflection. The basic scenario follows:
> Using reflection I create the object of the type in the my own assembly.
> Instance is created fine. Then use reflection to get info about type
fields.
> I want to use the field of the object just created:
>
> object field = fieldInfo.GetValue(form);
> switch (fieldInfo.FieldType.FullName)
> {
> case "System.Windows.Forms.TextBox":
> txtBox = (TextBox)field;
> break;
> default:
> break;
> }
> The cast statement txtBox = (TextBox)field; throws the
InvalidCastException.
> What I'm doing wrong ? Is casting not allowed on reflected types?
