C# Numerical Conversion-Implicit Numerical Conversion Table Reference

What is an implicit conversion

Implicit Conversion

Implicit conversion is to use it directly, for example, you can use a byte type directly on int.

For example, the following directly assigns b of byte to n of int, and uses it directly. There are no additional keywords, and the system automatically completes the type conversion.



Implicit numerical conversion table (excerpted from MSDN)

from	arrive
sbyte	short、int、long、float、double or decimal
byte	short、ushort、int、uint、long、ulong、float、double or decimal
short	int、long、float、double or decimal
ushort	int、uint、long、ulong、float、double or decimal
int	long、float、double or decimal
uint	long、ulong、float、double or decimal
long	float、double or decimal
char	ushort、int、uint、long、ulong、float、double or decimal
float	double
ulong	float、double or decimal

Notes (excerpted from MSDN)

The accuracy of the conversion from int, uint, or long to float and from long to double may be reduced, but the numerical size is not affected.

There is no implicit conversion to char type.
There is no implicit conversion between floating point type and decimal type.
A constant expression of type int can be converted to sbyte, byte, short, ushort, uint, or ulong, provided that the value of the constant expression is within the range of the target type.
