将字节[]转换为字符串似乎很简单，但任何一种编码都有可能把输出字符串弄乱。这个小函数只是工作，没有任何意想不到的结果:

private string ToString(byte[] bytes)
{
    string response = string.Empty;

    foreach (byte b in bytes)
        response += (Char)b;

    return response;
}

应用(字节)b to弦(“x2”)，Outputs b4b5dfe475e58b67

public static class Ext {

    public static string ToHexString(this byte[] hex)
    {
        if (hex == null) return null;
        if (hex.Length == 0) return string.Empty;

        var s = new StringBuilder();
        foreach (byte b in hex) {
            s.Append(b.ToString("x2"));
        }
        return s.ToString();
    }

    public static byte[] ToHexBytes(this string hex)
    {
        if (hex == null) return null;
        if (hex.Length == 0) return new byte[0];

        int l = hex.Length / 2;
        var b = new byte[l];
        for (int i = 0; i < l; ++i) {
            b[i] = Convert.ToByte(hex.Substring(i * 2, 2), 16);
        }
        return b;
    }

    public static bool EqualsTo(this byte[] bytes, byte[] bytesToCompare)
    {
        if (bytes == null && bytesToCompare == null) return true; // ?
        if (bytes == null || bytesToCompare == null) return false;
        if (object.ReferenceEquals(bytes, bytesToCompare)) return true;

        if (bytes.Length != bytesToCompare.Length) return false;

        for (int i = 0; i < bytes.Length; ++i) {
            if (bytes[i] != bytesToCompare[i]) return false;
        }
        return true;
    }

}

另外:

 var byteStr = Convert.ToBase64String(bytes);

string result = System.Text.Encoding.UTF8.GetString(byteArray);

这是一个不需要编码的结果。我在我的网络类中使用它，并以字符串的形式发送二进制对象。

public static byte[] String2ByteArray(string str)
{
    char[] chars = str.ToArray();
    byte[] bytes = new byte[chars.Length * 2];

    for (int i = 0; i < chars.Length; i++)
        Array.Copy(BitConverter.GetBytes(chars[i]), 0, bytes, i * 2, 2);

    return bytes;
}

public static string ByteArray2String(byte[] bytes)
{
    char[] chars = new char[bytes.Length / 2];

    for (int i = 0; i < chars.Length; i++)
        chars[i] = BitConverter.ToChar(bytes, i * 2);

    return new string(chars);
}

当你不知道编码时，从字节数组转换到字符串的一般解决方案:

static string BytesToStringConverted(byte[] bytes)
{
    using (var stream = new MemoryStream(bytes))
    {
        using (var streamReader = new StreamReader(stream))
        {
            return streamReader.ReadToEnd();
        }
    }
}
