Question

basically

I have

string s = "Foo"

I need to obtain

 Type t = IRepo<Foo>

but from string

Answer 1

Something like this, using Type.MakeGenericType:

Type arg = Type.GetType(s);
Type definition = typeof(IRepo<>);
Type concrete = definition.MakeGenericType(arg);

Note that Type.GetType(string) comes with a few caveats:

• You need to specify the type’s full name, including namespace
• If you want to get a type from an assembly other than mscorlib or the calling assembly, you have to include the assembly name
• If you’re including the assembly name and it’s strongly typed, you need the full assembly name including version etc.
