How to call generic method if I have only Type instance?

class A
{

}

...
Type type = GetSomeType();

Then I need to call A.M<T>() where type == typeof(T).

Reflection?

Yes, you need reflection. For example:

var method = typeof(A).GetMethod("M");
var generic = method.MakeGenericMethod(type);
generic.Invoke(null, null);

Because the type is known at runtime you need to use reflection:

Type type = GetSomeType();
var m = typeof(A)
    .GetMethod("M", BindingFlags.Static | BindingFlags.Public)
    .MakeGenericMethod(type);
m.Invoke(null, null);
