c# - WCF 异常 : The maximum message size quota for incoming messages (65536) has been exceeded

Question

当我调用 WCF 服务时出现异常:

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

当我在 http 上使用 Wireshark 数据包分析器过滤器时，发送的最大数据包为 1226 字节，远低于 65536 字节的限制。对抛出此异常的原因有何建议？

我怀疑导致异常的代码:

public LoanPlan CalculateLoanPlans(string productName)
{
    var loanPlan = new LoanPlan
    {
        Details = new[]
        {
            new PlanDetails {LoanAmount = 5000, Periods = 6},
            new PlanDetails {LoanAmount = 5000, Periods = 12},
            new PlanDetails {LoanAmount = 5000, Periods = 24},

            new PlanDetails {LoanAmount = 10000, Periods = 6},
            new PlanDetails {LoanAmount = 10000, Periods = 12},
            new PlanDetails {LoanAmount = 10000, Periods = 24},

            new PlanDetails {LoanAmount = 15000, Periods = 6},
            new PlanDetails {LoanAmount = 15000, Periods = 12},
            new PlanDetails {LoanAmount = 15000, Periods = 24},

            new PlanDetails {LoanAmount = 20000, Periods = 6},
            new PlanDetails {LoanAmount = 20000, Periods = 12},
            new PlanDetails {LoanAmount = 20000, Periods = 24},

            new PlanDetails {LoanAmount = 30000, Periods = 6},
            new PlanDetails {LoanAmount = 30000, Periods = 12},
            new PlanDetails {LoanAmount = 30000, Periods = 24},

            new PlanDetails {LoanAmount = 40000, Periods = 6},
            new PlanDetails {LoanAmount = 40000, Periods = 12},
            new PlanDetails {LoanAmount = 40000, Periods = 24},

            new PlanDetails {LoanAmount = 50000, Periods = 6},
            new PlanDetails {LoanAmount = 50000, Periods = 12},
            new PlanDetails {LoanAmount = 50000, Periods = 24}
        },
        TaxProcent = _taxPercent,
     };
     Parallel.ForEach(loanPlan.Details, detail =>
     {
         var result = Calculate(productName, Convert.ToInt32(detail.LoanAmount), detail.Periods, null);

         detail.ActualPaymentCost = result.ActualPaymentCost;
         detail.CreditCost = result.CreditAmount;
         detail.MonthlyPayment = result.MonthlyPayment;
         detail.MonthlyPaymentCost = result.MonthlyPaymentCredit;
     });

     var firstDetail = loanPlan.Details[0];
     var firstResult = Calculate(productName, Convert.ToInt32(firstDetail.LoanAmount), firstDetail.Periods, null);

     loanPlan.MonthlyFee = firstResult.MonthlyFee;
     loanPlan.MonthlyInterest = firstResult.MonthlyInterest;

     return loanPlan;
}

Calculate 方法包含服务调用。

增加服务器和客户端的 maxStringContentLength & maxArrayLength="2147483647"。检查下面的详细解释的链接
