如何在BlindingList C#WinForms中查找对象 [英] how to find objects in blindingList C# WinForms

问题描述

我有存储在绑定到DataGridView控件的bindingList中的对象的集合，我需要能够基于某些属性来定位对象，即每个对象都有一个propertyID.我需要执行此操作而无需遍历整个集合.

有人可以指出正确的方向吗?

预先感谢，

I have collection of objects that are stored within a bindingList that''s bound to a DataGridView control and I need to be able to locate objects based on certain properties i.e. each object has a propertyID. I need to do this without iterating through the collection.

Can someone please point me the right direction to accomplish this.

Thanks in advance,

推荐答案

如果要通过其ID查找对象，例如15 = 5
然后:

If you want to find an object by it''s id, for example 15 = 5
then:

var foundObject = myList.Where(o=>o.propertyID == 5).First()

更好:

假设对象是Person的实例:

And Better:

Imagin the object is an instance of Person:

Person person;

var foundObject = myList.Where(o=>o.propertyID == 5);

if(foundObject.Count()>0)
   person = foundObject.First();
