Default Values Table (C# Reference)

The following table shows the default values of value types returned by the default constructors. Default constructors are invoked by using the new operator, as follows:

int myInt = new int();

The preceding statement has the same effect as the following statement:

int myInt = 0;

Remember that using uninitialized variables in C# is not allowed.

Value type	Default value
bool	false
byte	0
char	'\0'
decimal	0.0M
double	0.0D
enum	The value produced by the expression (E)0, where E is the enum identifier.
float	0.0F
int	0
long	0L
sbyte	0
short	0
struct	The value produced by setting all value-type fields to their default values and all reference-type fields to null.
uint	0
ulong	0
ushort	0
