class TestClass<T>
{
  public void GetName<string>()
  {
      //do work knowing that the type is a string    
  }

  public string GetName<int>()
  {
      //do work knowing that the type is an int

  } 

  public string GetName<int>(int addNumber)
  {
      //do work knowing that the type is an int (overloaded)    
  } 

  public string GetName<DateTime>()
  {
      //do work knowing that the type is a DateTime

  } 

  public string GetName<customObject>()
  {
      //do work knowing that the type is a customObject type    
  }

}

所以现在我可以调用GetName方法,因为我已经在初始化对象时传入了类型,所以找到并执行正确的方法.

TestClass foo = new TestClass<int>();

//executes the second method because that's the only one with a "int" type
foo.GetName();

这是可能还是我只是在做梦？

解决方法

class TestClass<T>
{
   public string GetName<T>()
   {
      Type typeOfT = typeof(T);
      if(typeOfT == typeof(string))
      {
          //do string stuff
      }
   }
}
