C#MD5为密码加密
byte[] date = Encoding.Unicode.GetBytes(txtPassword.Text.ToCharArray());
MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
byte[] result = md5.ComputeHash(date);
string sResult = Encoding.Unicode.GetString(result);
string EnPswdStr = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Text.Trim(),
EnPswdStr 为加密的码 txtPassword为TextBox,输入密码的地方
