【顶贴给分】：谁能帮忙把这段JAVA代码转换成C#的？

[m777]

public final static String getMd5(String strSrc) throws Exception {
char hexDigits[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'a', 'b', 'c', 'd', 'e', 'f' };

byte[] strTemp = strSrc.getBytes(Constant.ENC);
MessageDigest mdTemp = MessageDigest.getInstance(Constant.MD5);
mdTemp.update(strTemp);
byte[] md = mdTemp.digest();
int j = md.length;
char str[] = new char[j * 2];
int k = 0;
for (int i = 0; i < j; i++) {
byte byte0 = md[i];
str[k++] = hexDigits[byte0 >>> 4 & 0xf];
str[k++] = hexDigits[byte0 & 0xf];
}
return new String(str);

}

用不着上网找，.Net已经自带md5类啊

using System;
using System.Security.Cryptography;
using System.Text;

    // Hash an input string and return the hash as
    // a 32 character hexadecimal string.

    {

        MD5 md5Hasher = MD5.Create();

        // Convert the input string to a byte array and compute the hash.
        byte[] data = md5Hasher.ComputeHash(Encoding.Default.GetBytes(input));

        // Create a new Stringbuilder to collect the bytes
        // and create a string.
        StringBuilder sBuilder = new StringBuilder();

        // Loop through each byte of the hashed data 
        // and format each one as a hexadecimal string.
        for (int i = 0; i < data.Length; i++)
        {
            sBuilder.Append(data[i].ToString("x2"));
        }

        // Return the hexadecimal string.
        return sBuilder.ToString();
    }

        }
        else
        {
            return false;
        }
    }


    static void Main()

晕，似乎没法运行吧？

[ericzhangbo1982111]

public string GetMD5Hash(string input)
{
System.Security.Cryptography.MD5CryptoServiceProvider x = new System.Security.Cryptography.MD5CryptoServiceProvider();
byte[] bs = System.Text.Encoding.UTF8.GetBytes(input);
bs = x.ComputeHash(bs);
System.Text.StringBuilder s = new System.Text.StringBuilder();
foreach (byte b in bs)
{
s.Append(b.ToString("x2").ToLower());
}
string password = s.ToString();
return password;
}
