Console.WriteLine("value = short1: {0,17}", value.Equals(short1));
TestObjectForEquality(short1);
int int1 = 112;
Console.WriteLine("value = int1: {0,19}", value.Equals(int1));

TestObjectForEquality(long1);
sbyte sbyte1 = 112;
Console.WriteLine("value = sbyte1: {0,17}", value.Equals(sbyte1));
TestObjectForEquality(sbyte1);
ushort ushort1 = 112;
Console.WriteLine("value = ushort1: {0,17}", value.Equals(ushort1));
TestObjectForEquality(ushort1);
uint uint1 = 112;
Console.WriteLine("value = uint1: {0,19}", value.Equals(uint1));
