private string GetValue(string TobeGetStr, string FieldName)

            if (TobeGetStr == "" || FieldName == "")
            {
                return "";
            }
            string[] tempArr= TobeGetStr.Split(new char[]{'&'});
            for (int i = 0; i < tempArr.Length; i++)

调用如下：

           OrderNo  = GetValue(DecryptedMsg, "OrderNo");  //商户订单号
            PayNo   = GetValue(DecryptedMsg, "PayNo");      //支付单号
            PayAmount  = GetValue(DecryptedMsg, "PayAmount");  //支付金额，格式：元.角分
            CurrCode  = GetValue(DecryptedMsg, "CurrCode");  //货币代码
            SystemSSN  = GetValue(DecryptedMsg, "SystemSSN");
