Convert Byte To String

Question

I would like to convert a byte to a string.

Example:

byte testByte = 0x05;

testByte should be converted to "00000101"

I have tried Convert.ToString(testByte, 2), but it only returns "101"

Answer 1

您已经非常接近了，您需要做的就是在已经生成的String上调用PadLeft ：

Convert.ToString(testByte, 2).PadLeft(8,'0');

Answer 2

static string ToBase2String(int n, int pad)
{
    var s = n < 0 ? "-" : "";
    var v = n < 0 ? -n : n;

    while (v > 0)
    {
        s = (v % 2 == 0 ? "0" : "1") + s;
        v /= 2;
    }

    return s.PadLeft(pad, '0');
}
