Error creating runtime object of type System.Drawing.Point

Question

I want to create a object of type System.Drawing.Point at runtime, I tried to use the code below:

String typename = "System.Drawing.Point";
Type tp = Type.GetType(typename);
Object instance = Activator.CreateInstance(tp);

But I always get tp == null. But, for example if I use System.Double everything is ok.

Answer 1

You need to qualify the assembly in your type name, so

String typename = "System.Drawing.Point, System.Drawing";

will work (if System.Drawing.dll is referenced and loaded).

typeName

Type: System.String

The assembly-qualified name of the type to get. [..] If the type is in the currently executing assembly or in Mscorlib.dll, it is sufficient to supply the type name qualified by its namespace.

Answer 2

Type.GetType will try to load the type from mscorlib. Use assembly-qualified name of the type.

String typename = "System.Drawing.Point, System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a";

Type tp = Type.GetType(typename);
