解决方法的类型参数不能从使用推断

Question

我得到这个错误： 方法'ConsoleApplication1.Program.takeList<T>（System.ComponentModel.BindingList<T>）'的类型参数不能从使用推断。尝试明确指定类型参数。

我相信编译器无法猜测chooseList方法的返回类型，但它必须将它传递给takeList方法。有没有办法让这个工作，但不解耦chooseList方法到Main函数??

class Program 
{ 
    static BindingList<int> listOfInts; 
    static BindingList<string> listOfStrings; 
    //more lists 

    static void takeList<T>(BindingList<T> list) 
    { 
     //do something 
     return; 
    } 

    static object chooseList() //instead of object i would put BindingList<T> 
    { 
     int someCondition = 0; 

     //code that changes someCondition so compiler doesnt know its value 

     switch (someCondition) 
     { 
      case 1: return listOfInts; 

      //more cases for more lists 

      default: return listOfStrings; 
     } 
    } 

    static void Main(string[] args) 
    { 
     Program testClass = new Program(); 
     var chosenList = chooseList(); 
     takeList(chosenList); 
    } 
} 

编辑：

这里是一个相反的情况应该工作。我想将它转化成以上：

class Program 
{ 
    static BindingList<int> listOfInts; 
    static BindingList<string> listOfStrings; 
    //more lists 

    static void takeList<T>(BindingList<T> list) 
    { 
     //do something 
     return; 
    } 

    static void Main(string[] args) 
    { 
     Program testClass = new Program(); 

     int someCondition = 0; 

     //code that changes someCondition so compiler doesnt know its value 

     switch (someCondition) 
     { 
      case 1: 
       takeList(listOfInts); 
       break; 

      //more cases for more lists 

      default: 
       takeList(listOfStrings); 
       break; 
     } 

     //Instead of the switch here, i would like to write takelist(doTheSwitch(someCondition)); 
    } 
}
