如何通过对象的属性从自定义对象列表中删除重复项
问题描述：
我要根据对象的属性删除重复项:
I want to remove the duplicates based on a property of my object:
public class MyType
{
public string _prop1;
public string _prop2;
public LocationsClass(string prop1, string prop2)
{
_prop1= prop1;
_prop2= prop2;
}
}
...
List<MyType> myList;
因此，基本上我想从myList中删除所有MyType对象，并在_prop1中使用相同的值.有可能使用LINQ来做到这一点吗?
So basically I want to remove all MyType objects from myList, with the same value in _prop1. Is there a way to do this, probably with LINQ?
答
var distinctItems = myList.GroupBy(x => x.prop1).Select(y => y.First());
