c# 整數類型轉byte

Here is the list of the built-in integral types of data types in C#, sbyte, byte, char, short, ushort, int, uint, long and ulong

這是C＃， sbyte ， byte ， char ， short ， ushort ， int ， int ， uint ， long和ulong中數據類型的內置整數類型的列表

C＃數據類型的積分類型 (C# Integral types of Data types)

Type	System type	Size (in bits)	Value Range	Value type
sbyte	System.SByte	8-bits	-128 to 127	Signed integer
byte	System.Byte	8-bits	0 to 255	Unsigned integer
char	System.Char	16-bits	U+0000 to U+ffff	Unicode character
short	System.Int16	16-bits	-32,768 to 32,767	Signed integer
ushort	System.Int16	16-bits	0 to 65,535	Unsigned integer
int	System.Int32	32-bits	-2,147,483,648 to 2,147,483,647	Signed integer
uint	System.Int32	32-bits	0 to 4,294,967,295	Unsigned integer
long	System.Int64	64-bits	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807	Signed integer
ulong	System.Int64	64-bits	0 to 18,446,744,073,709,551,615	Unsigned integer

類型	系統類型	大小(以位為單位)	取值范圍	值類型
兆字節	系統字節	8位	-128至127	有符號整數
字節	系統字節	8位	0至255	無符號整數
燒焦	系統字符	16位	U + 0000至U + ffff	Unicode字符
短	System.Int16	16位	-32,768至32,767	有符號整數
超短	System.Int16	16位	0至65,535	無符號整數
整型	System.Int32	32位	-2,147,483,648至2,147,483,647	有符號整數
int	System.Int32	32位	0至4,294,967,295	無符號整數
長	System.Int64	64位	-9,223,372,036,854,775,808至9,223,372,036,854,775,807	有符號整數
烏龍	System.Int64	64位	0至18,446,744,073,709,551,615	無符號整數

Example:

例：

In this example, we are declaring variables of different integral types of data types, initializing with the different value, printing the system types of the variables, size of the types and min, max values of the types.

在此示例中，我們聲明了不同整數類型的數據類型的變量，使用不同的值進行初始化，打印了變量的系統類型，類型的大小以及類型的最小值，最大值。
