MD5哈希值计算:(仅仅是记录一下)

/// <summary>
/// 获取字符串的MD5值
/// </summary>
/// <param name="str">字符串</param>
/// <param name="salt">加盐值</param>
/// <returns></returns>
public static string MD5(this string str, string salt = "")
{
//MD5计算类
using (System.Security.Cryptography.MD5CryptoServiceProvider md5 = new System.Security.Cryptography.MD5CryptoServiceProvider())
{
byte[] bytValue, bytHash;
//将要计算的字符串转换为字节数组
bytValue = System.Text.Encoding.UTF8.GetBytes(salt + str);
//计算结果同样是字节数组
bytHash = md5.ComputeHash(bytValue);
//将字节数组转换为字符串
string sTemp = "";
for (int i = 0; i < bytHash.Length; i++)
{
sTemp += bytHash[i].ToString("x").PadLeft(2, '0');
}
return sTemp;
}
}
