Question

I’m developing a WCF JSON Web Service which receive data from an Android application.

Some data could be null. On Android I’m using java.lang.Long, that could be null.

On C#side, I’m using long that couldn’t be null.

Is there a java.lang.Long type in C#?

Answer 1

Sounds like you want a Nullable<long> or long?.

long? myLongVar = null;
if (myLongVar == null) // or !myLongVar.HasValue, if you prefer
{
    myLongVar = 5L;
    long noLongerNullable = myLongVar.Value;
}
