为此有一个内置方法:

byte[] data = { 1, 2, 4, 8, 16, 32 };

string hex = BitConverter.ToString(data);

结果:01-02-04-08-10-20

Result: 01-02-04-08-10-20

如果你想要没有破折号，只需删除它们:

If you want it without the dashes, just remove them:

string hex = BitConverter.ToString(data).Replace("-", string.Empty);

结果:010204081020

Result: 010204081020

如果你想要更紧凑的表示，你可以使用 Base64:

If you want a more compact representation, you can use Base64:

string base64 = Convert.ToBase64String(data);
