Byte array values
WebA byte is a group of 8 bits. A bit is the most basic unit and can be either 1 or 0. A byte is not just 8 values between 0 and 1, but 256 (2 8) different combinations (rather permutations) ranging from 00000000 via e.g. 01010101 to 11111111. Thus, one byte can represent a decimal number between 0 (00) and 255. Puzzled? WebThe following code example converts the bit patterns of Int32 values to Byte arrays with the GetBytes method. C# using System; class Example { public static void Main( ) { // Define an array of integers. int[] values = { 0, 15, -15, 0x100000, -0x100000, 1000000000, -1000000000, int.MinValue, int.MaxValue }; // Convert each integer to a byte array.
