【转载】C#中通过Distinct方法对List集合进行去重

  list<int> intlist= new list<int>() { 1, 1,2,2,3,4,5};
 intlist= intlist.distinct().tolist();

   list<testmodel> testlist = new list<consoleapplication1.testmodel>();
   testlist.add(new testmodel()
   {
       index=1,
       name="index1"
   });
   testlist.add(new testmodel()
   {
       index = 2,
       name = "index2"
   });
   testlist.add(new testmodel()
   {
       index = 2,
       name = "index2"
   });
   testlist = testlist.distinct().tolist();
