Then anywhere this method is in scope you could use, for example:

string s = "12345";
>>int? i = s.ToNullableInt();

Note the above implementation would return null for any string that doesn't translate to a valid int (null, string.empty, "123.45", "asd" etc.) which may no be exactly what you want. And I wouldn't bother to implement this unless you know it will have a wider use than in your original requirement....

Didn't know that. In that case you'd have to rely on Convert and add more error checking....
Maybe it would be a good idea for UT to have a .NET CE section - I sometimes forget you're working with CE....
