将16字节数组响应转换为十进制数-Conversionof16ByteArrayResponsetoDecimal

I am working on an application in which I received a 16 byte array response. In that response there will be 1 bit set to indicate a position value. For example I may get:

我正在处理一个应用程序，其中我收到了一个16字节的数组响应。在该响应中，将设置1位以指示位置值。例如，我可能得到：

0000 01000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000

0000 01000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000

Which would represent that device #5 has responded (first bit represents device #0).

这表示设备＃5已响应（第一位表示设备＃0）。

Is there a simple way to get convert a byte array of this length to it's decimal value?

是否有一种简单的方法可以将此长度的字节数组转换为十进制值？

int n = 0;

// Loop trough the byte array.
for(n = 0; n 

byte[] yourByteArr = { 0, 0, 32, 0, };

var firstSetBit = (new BitArray(yourByteArr)).Cast()
    .Select(Tuple.Create).FirstOrDefault(x => x.Item1);
int indexOfFirstSetBit = firstSetBit != null ? firstSetBit.Item2 : -1;

int indexOfFirstSetBit = (new BitArray(yourByteArr)).Cast()
    .Select(Tuple.Create).First(x => x.Item1).Item2;
