c# - C#编译器正在尝试编译为错误的重载方法

Question

我的项目是使用.Net 4.5的VS2012。

我的课上有以下重载方法:

public SalesOrder GetSalesOrder(int salesOrderID, bool forceRefresh = false)
{
    using (iSeriesUOW uow = new iSeriesUOW())
    {
        return GetSalesOrder(uow, salesOrderID, forceRefresh);
    }
}

public SalesOrder GetSalesOrder(iSeriesUOW uow, int salesOrderID, bool forceRefresh = false)
{
    .... do some stuff here
}

我正在尝试使用以下方法调用第一个方法:

public void PopulateModel(string companyCode, int salesOrderID, bool forceRefresh)
{
    SalesOrders blSalesOrders = new SalesOrders(companyCode);
    SalesOrder salesOrder = blSalesOrders.GetSalesOrder(salesOrderID, forceRefresh);

    ... Other code here
}

编译器在我的GetSalesOrder调用中给了我一个错误:

The type 'DataAccess.iSeriesUOW' is defined in an assembly that is not referenced. You must add a reference to assembly 'Viper.DataAccess, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.  

如果我删除GetSalesOrder中的forceRefresh，则可以正常编译。

我在想它正在尝试调用第二次GetSalesOrder重载，但是我不知道为什么，因为(int，bool)的签名显然存在。

有任何想法吗？

Answer 1

我会尝试显式设置参数值:

代替

 SalesOrder salesOrder = blSalesOrders.GetSalesOrder(salesOrderID, forceRefresh);

我会尝试

public void PopulateModel(string companyCode, int salesOrderID, bool forceRefreshParam)
{
    SalesOrders blSalesOrders = new SalesOrders(companyCode);
    SalesOrder salesOrder = blSalesOrders.GetSalesOrder(salesOrderID, forceRefresh:forceRefreshParam);

    ... Other code here
}
