create nullable type with string

[Dan Holmes]

i need to get an object of type Type when i have a string. That is the
easy part (Type.GetType(" int")). What if i want that type to be
nullable? This doesn't work Type.GetType("i nt?"). It returns null.

This does work but i don't know how to know all that information at runtime.

Type.GetType("S ystem.Nullable` 1[[System.Int32, mscorlib,
Version=2.0.0.0 , Culture=neutral , PublicKeyToken= b77a5c561934e08 9]]")

Re: create nullable type with string

Dan,

Assuming you have the type for T in Nullable<T>, you can do the
following:

// This is where you would get typeof(int)
Type typeParameter = ...

// Get the Nullable<Tgener ic type.
Type nullable = typeof(Nullable <>);

// Now make the constructed type.
Type constructedType = nullable.MakeGe nericType(new Type[]{typeParameter} );
