When does `Assembly.GetType(name)` return `null`?

Question

I have a code like shown below

public static Type ToType(Type sType)
{    
    Assembly assembly = Assembly.Load(SerializableType.AssemblyName);
    type = a         


        

Answer 1

Your type may be non public, by default reflection only works on public types and members, unless you increase your level of security, type will be null.
