使用linq C#根据对象的innervariables值从列表创建子列表 [英] creating a sublist from a list based on object's innervariables value using linq c#

问题描述

我有对象list1的列表，我想从该列表中选择一个List< object>.用
说"obj" obj.type ="1001"
请建议对此的Linq查询

I have list of object list1 ,from this list i want to select a List<object> say "obj" with
obj.type="1001"
Please suggest Linq query for this

推荐答案

我遇到了您的问题:

使用以下代码:

var

I got your problem:

Use the below code:

var

obj = new List<test>();
            var res = obj.FirstOrDefault( x => x.Type = "1001");
            if (res != null)
            {
                //Process result
            }

首先，没有名称扩展名为"type"的对象
这是我尽可能接近我认为您要询问的LINQ查询:

First of all there is no extension to object with the name "type"
Here is the LINQ query as close as I can get to what I think you are asking:

var list1 = new List<object>();
list1.Add("Something");
var item = list1.FirstOrDefault(i => i.GetType().ToString() == "System.String");
Console.WriteLine(item.GetType());
Console.ReadLine();
