显示两个数组中不匹配的值 [英] Show non matched values from two arrays

问题描述

如何将每个数组中没有对的项目放入 ListBox 的集合中?

How do I put into the collection of ListBox those items that doesn't have a pair from each array?

例如:

第一个数组= 100500

first array = 100 500

第二个数组= 100200300400500600700800

second array = 100 200 300 400 500 600 700 800

现在，如何将那些不匹配的值(200,400,600,700,800)显示在 ListBox 中?

Now, how do I show those non matched values (200,400,600,700,800) into ListBox?

推荐答案

您可以使用LINQ和 Except 方法:

You can use LINQ and Except method:

int[] result = secondArray.Except(firstArray).ToArray();
yourListBox.DataSource = result;

此外，如果要在 firstArray 中包含不在 secondArray 中的值，请使用以下查询:

Also if you want to include values in firstArray that are not in secondArray go with the following query:

var result = firstArray.Except(secondArray).Union(secondArray.Except(firstArray)).ToArray();
