Bit field c#
Web所谓"位域"是把一个字节中的二进位划分为几个不同的区域，并说明每个区域的位数。 每个域有一个域名，允许在程序中按域名进行操作。 这样就可以把几个不同的对象用一个字节的二进制位域来表示。 典型的实例： 用 1 位二进位存放一个开关量时，只有 0 和 1 两种状态。 读取外部文件格式——可以读取非标准的文件格式。 例如：9 位的整数。 位域的定义和 … WebOct 6, 2024 · Flags / bit fields as Enum in C# by admincode October 6, 2024 Enum in C# is a powerful construct.

WebTo check a bit, shift the number n to the right, then bitwise AND it: bit = (number >> n) & 1U; That will put the value of the n th bit of number into the variable bit. Changing the n th bit to x Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); WebDeclaring Bit FIelds. Variables that are defined using a predefined width or size are called bit fields. This bit field can leave more than a single bit.
