在c#中将小端序转换为大端序
本文关键字:转换 | 更新日期: 2023-09-27 18:21:05
我想将字符串"8BABEEF9D2472E65"转换为big-endian。
我已经输入了这个函数,我收到UINT大小错误。。我该怎么办?
功能:
string bigToLittle(string data)
{
int number = Convert.ToInt32(data, 16);
byte[] bytes = BitConverter.GetBytes(number);
string retval = "";
foreach (byte b in bytes)
retval += b.ToString("X2");
return retval;
}
我认为您可以使用System.Runtime.Remoting.Metadata.W3cXsd2001.SoapHexBinary
类。
string input = "8BABEEF9D2472E65";
var output = new SoapHexBinary(SoapHexBinary.Parse(input).Value.Reverse().ToArray())
.ToString();
输出:652E47D2F9EEAB8B
或者
var output = IPAddress.HostToNetworkOrder(long.Parse(input, NumberStyles.HexNumber))
.ToString("X");
由于我们无法猜测你想要什么样的输出,我让自己写下了缺失的可能性(在代码注释中)。。。你可以选择你真正需要的:
internal class Program
{
private static int ReverseBytes(long val)
{
byte[] intAsBytes = BitConverter.GetBytes(val);
Array.Reverse(intAsBytes);
return BitConverter.ToInt32(intAsBytes, 0);
}
private static string IntToBinaryString(long v)
{
string s = Convert.ToString(v, 2);
string t = s.PadLeft(32, '0');
string res = "";
for (int i = 0; i < t.Length; ++i)
{
if (i > 0 && i%8 == 0)
res += " ";
res += t[i];
}
return res;
}
private static void Main(string[] args)
{
string sValue = "8BABEEF9D2472E65";
long sValueAsInt = long.Parse(sValue, System.Globalization.NumberStyles.HexNumber);
//output {-8382343524677898651}
string sValueAsStringAgain = IntToBinaryString(sValueAsInt);
//output {10001011 10101011 11101110 11111001 11010010 01000111 00101110 01100101}
byte[] data = Encoding.BigEndianUnicode.GetBytes(sValue);
string decodedX = Encoding.BigEndianUnicode.GetString(data);
string retval = data.Aggregate("", (current, b) => current + b.ToString("X2"));
//output {0038004200410042004500450046003900440032003400370032004500360035}
char[] decodedX2 = Encoding.BigEndianUnicode.GetString(data).Reverse().ToArray();
StringBuilder retval2 = new StringBuilder(); //output {56E2742D9FEEBAB8}
foreach (var b in decodedX2)
retval2.Append(b);
Console.ReadLine();
}
}
}
关于你的方法:
public static string bigToLittle(string data)
{
long sValueAsInt = long.Parse(data, System.Globalization.NumberStyles.HexNumber);
byte[] bytes = BitConverter.GetBytes(sValueAsInt);
string retval = "";
foreach (byte b in bytes)
retval += b.ToString("X2");
return retval; //output {652E47D2F9EEAB8B}
}
我喜欢@Sebatsian的回答,但我遇到了用额外的零填充条目的问题,所以我稍微修改了一下,以防你正在做一些事情,比如将Azure中的Linux VMUUID转换为标准格式。我使用了IPAddress.HostToNetworkOrder
,它处理将long分解为字节并反转它们。
private string BigToLittle(string data)
{
long sValueAsInt = long.Parse(data, System.Globalization.NumberStyles.HexNumber);
var length = data.Length;
return IPAddress.HostToNetworkOrder(sValueAsInt).ToString("X2").Substring(0, length);
}
使用中:
string uuid = "090556DA-D4FA-764F-A9F1-63614EDA0163";
private string BigToLittle(string data)
{
long sValueAsInt = long.Parse(data, System.Globalization.NumberStyles.HexNumber);
var length = data.Length;
return IPAddress.HostToNetworkOrder(sValueAsInt).ToString("X2").Substring(0, length);
}
var elements = uuid.Split(new char[] { '-' });
var outMe = new List<string> { };
foreach (var item in elements)
{
outMe.Add(BigToLittle(item));
}
var output = String.Join("-", outMe);
