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

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。
