IsNullableType doesn't works for Aliased Nullable types (TNullableString, TNullableInteger and so on)

[Daniele Teti]

In the function body, there's an hardcoded prefix for the type name that prevent to use it for nullable aliased types. It works as espected for Nullable<String> but not for TNullableString

function IsNullableType(typeInfo: PTypeInfo): Boolean; const PrefixString = 'Nullable<'; {this is hardcoded} begin Result := Assigned(typeInfo) and (typeInfo.Kind = tkRecord) and StartsText(PrefixString, GetTypeName(typeInfo)); end;

Sorry boys, there were something elso that invalidate the test... I redidi the test and with the aliases types it works... more to come.

Strange behaviour... now it works. Problebly I did some errors...

As these types are just aliases there is no new type defined. That means at runtime TNullableString is actually the type Nullable<string>.
