正确格式化json有效载荷

Question

我正在尝试将json有效负载格式化为这样，但是在Params属性上有一个语法错误。

   mailer.send2(new PayoutEmailModel
                    {
                        medium = "email",
                        name = "sap_finance_supplier_payout",
                        @params = @"{""supplier"":""" + BeneficiaryName + """,""lastfourdigits"":""" + AccountNo + """,""amount"":""" + Amount + """,""valuedate"":""" + BeneficiaryName + """,""time"":""" + BeneficiaryName + """}",
                        recipient = "dapo.olotu@konga.com",
                        sender = "no-reply@konga.com",
                        subject = "Payment Notification",
                        sender_id = "Konga"
                    });

编辑，我需要@Params正确地呈现如下

{"supplier":"foo","lastfourdigits":"foo","amount":"foo","valuedate":"foo","time":"foo"}

Answer 1

我认为Dinesh是对的，如果你按自己的方式去做，你可能不会得到预期的结果。但是，要回答您的问题，语法错误是因为您使用每个+运算符启动一个新字符串，但是没有使用新的@。

@{“供应商”：“”+ BeneficiaryName +@“”、“最后四位数”：“+ AccountNo +@”、“AccountNo”：“”+“AccountNo+@”、“valuedate”：“”+ BeneficiaryName +@“”、“”time“：”“+ BeneficiaryName +@”}，

Answer 2

尝试使用匿名类型

mailer.send2(new PayoutEmailModel
    {
        medium = "email",
        name = "sap_finance_supplier_payout",
        params = new { supplier = BeneficiaryName, lastfourdigits = AccountNo, amount = Amount, valuedate = BeneficiaryName, time = BeneficiaryName},
        recipient = "dapo.olotu@konga.com",
        sender = "no-reply@konga.com",
        subject = "Payment Notification",
        sender_id = "Konga"
    });
