如何通过对象的属性从自定义对象列表中删除重复项 [英] How to remove duplicates from a list of custom objects, by a property of the object

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?

推荐答案

var distinctItems = myList.GroupBy(x => x.prop1).Select(y => y.First());
