无法确定条件表达式的类型，因为int和string之间没有隐式转换

问题描述

这是代码，我有大胆的和平错误：

 var isIdSortable = Convert.ToBoolean（Request [bSortable_1 ]）; 
 
 var isNameSortable = Convert.ToBoolean（Request [bSortable_2]）; 
 var isAddressSortable = Convert.ToBoolean（Request [bSortable_3]）; 
 var isTownSortable = Convert.ToBoolean（Request [bSortable_4]）; 
 
 var sortColumnIndex = Convert.ToInt32（Request [iSortCol_0]）; 
 Func< Order，string> orderingFunction =（c =>  sortColumnIndex == 1&& isIdSortable？c.OrderID：
 sortColumnIndex == 2&& isNameSortable？c.CustomerID：
 sortColumnIndex == 3 && isAddressSortable？c.ShipAddress：
 sortColumnIndex == 4&& isTownSortable？c.ShipCountry：
）;  
 

OrderID是INT，CustomerID地址和国家是字符串

解决方案

This is the code and i have error to the bold peace :

var isIdSortable = Convert.ToBoolean(Request["bSortable_1"]);

           var isNameSortable = Convert.ToBoolean(Request["bSortable_2"]);
           var isAddressSortable = Convert.ToBoolean(Request["bSortable_3"]);
           var isTownSortable = Convert.ToBoolean(Request["bSortable_4"]);

           var sortColumnIndex = Convert.ToInt32(Request["iSortCol_0"]);
           Func<Order, string> orderingFunction = (c =>  sortColumnIndex == 1 && isIdSortable ? c.OrderID :
             sortColumnIndex == 2 && isNameSortable ? c.CustomerID :
                                                          sortColumnIndex == 3 && isAddressSortable ? c.ShipAddress :
                                                          sortColumnIndex == 4 && isTownSortable ? c.ShipCountry :
                                                          "");

OrderID is INT , CustomerID Adress and Country are string

What I have tried:

i just explained the problem above in the section
