会PHP的大婶帮忙把这个函数翻译成C#的~~

using System; using System.Text; using System.Security.Cryptography; public class Program { private const string key = " key " ; private const string message = " message " ; private static readonly Encoding encoding = Encoding.UTF8; static

using System;

using System.Text;

using System.Security.Cryptography;

public class Program {

private const string key = "key";

private const string message = "message";

private static readonly Encoding encoding = Encoding.UTF8;

static void Main(string[] args) {

var keyByte = encoding.GetBytes(key);

using (var hmacsha256 = new HMACSHA256(keyByte)) { hmacsha256.ComputeHash(encoding.GetBytes(message));

Console.WriteLine("Result: {0}", ByteToString(hmacsha256.Hash));

}

}

static string ByteToString(byte[] buff) {

string sbinary = "";

for (int i = 0; i )

sbinary += buff[i].ToString("X2");

/* hex format */ return sbinary; }

}
