Nullable type to string function
I just answered a thread where somebody wanted to know how to take any nullable type, check if it's value is null, and depending on that either return String.Empty or ToString. Here's how you do that:
public static string ConvertNullableToString<T>(T? value) where T : struct
{
return value.ToString() ?? String.Empty;
}
int? value1 = null;
int? value2 = 9;
string stringValue1 = ConvertNullableToString<int>(value1);
string stringValue2 = ConvertNullableToString<int>(value2);

Hi,
you could also do it like
return value ?? string.Empty;

Ah. Yes. The ?? operator escaped my head when I was creating the code. I just updated it with the ?? operator. Thanks.
