Convert uuid to byte array golang As can be seen, the function takes two other arguments the base and bitSize. The base is the numeric base to which the string is being converted. Base-10 is the decimal while the Base-2 is binary. The bitSize is the size of the int we must return. Examples. This example initializes an array of bytes , reverses the array if the computer architecture is little-endian (that is, the least significant byte is stored first), and then calls the ToInt32(Byte[], Int32) method to convert four bytes in the array to an int.The second argument to ToInt32(Byte[], Int32) specifies the start index of the <b>array</b> of <b>bytes</b>. To convert a string to byte array or slice in Go language use the below one liner code.
