比较C#中的2个列表 [英] Comparing 2 Lists in C#

问题描述

首先，我是编码的新手，这是我的第一个正式申请.

我需要为客户编写一个应用程序，在其中将数据输入到文本"框中.

然后需要在后台比较数据，并在下面显示结果.

例子
IE.方框A包含:1 2 3 4
方框B包含:2 3 4 5

结果应为:
方框A:5
方框B:1

此应用程序的原因是用户将从两个来源粘贴订单号列表.将比较这两个列表并显示结果.这意味着需要输入和分离粘贴的数据(以便每个订单号在列表中都有它自己的值).

我已经显示了正在工作的数据.而且我认为数据拆分是有效的.我现在需要做的是比较数据，并确认将数据拆分为单独的条目.

这是我目前正在使用的代码:

 // 左侧收藏条目
           List< string> leftCollection = 新 List< string>();
           leftCollection.Add(txtLeftCollection.Text);

           txtLeftResult.Text = Convert.ToString(leftCollection);
           txtLeftResult.Text = " ;
           txtLeftResult.Text + = leftCollection [ 0 ];

           字符串 splitLeft = Convert.ToString(leftCollection);

           字符串 [] wordsL = splitLeft.Split('  \ n ');
            foreach (字符串单词 in  wordsL)
           {
               Console.WriteLine(word);
           }

           // 权利收集条目
           List< string> rightCollection = 新 List< string>();
           rightCollection.Add(txtRightCollection.Text);

           txtRightResult.Text = Convert.ToString(rightCollection);
           txtRightResult.Text = " ;
           txtRightResult.Text + = rightCollection [ 0 ];


           字符串 splitRight = Convert.ToString(leftCollection);

           字符串 [] wordsR = splitRight.Split('  \ n ');
            foreach (字符串单词 in  wordsR)
           {
               Console.WriteLine(word);
           }

有人可以帮我吗.

提前谢谢您.

Try this

namespace ConsoleApplication17
{
    class Program
    {
        static void Main()
        {
            string s1 = "1 2 3 4";
            string s2 = "2 3 4 5";



            string[] arrayOne = s1.Split(' ');
            string[] arrayTwo= s2.Split(' ');
            string Left=string.Empty;
            string Right=string.Empty;
            foreach (string word in arrayOne)
            {
                if (!(arrayTwo.Contains(word)))
                {
                    if (Left == string.Empty)
                        Left = word;
                    else
                        Left = Left + " " + word;
                }
            }
            foreach (string word in arrayTwo)
            {
                if (!(arrayOne.Contains(word)))
                {
                    if (Right == string.Empty)
                        Right = word;
                    else
                        Right = Right + " " + word;
                }
            }

            Console.WriteLine(Left);
            Console.WriteLine(Right);
            Console.Read();
        }

    }
}

Thank you for the help

here is my solution

{
            //Clear previous Results
            txtLeftResult.Text = "";
            txtRightResult.Text = "";

            //Left Collection Entries
            List<string> leftCollection = new List<string>();
            leftCollection.AddRange(txtLeftCollection.Text.Split(new string[] { "\r\n" }, StringSplitOptions.None));            
            //Right Collection Entries
            List<string> rightCollection = new List<string>();
            rightCollection.AddRange(txtRightCollection.Text.Split(new string[] { "\r\n" }, StringSplitOptions.None));

            //Loop through left collection
            foreach (string row in leftCollection)
            {
                if (!rightCollection.Contains(row))
                {
                    txtLeftResult.Text = txtLeftResult.Text + "\r\n" + row;
                }
            }
            if (txtLeftResult.Text.Length > 0)
            {
               txtLeftResult.Text = txtLeftResult.Text.Remove(0, 2);
            }

            //Loop through Right collection
            foreach (string row in rightCollection)
            {
                if (!leftCollection.Contains(row))
                {
                    txtRightResult.Text = txtRightResult.Text + "\r\n" + row;
                }
            }
            if (txtRightResult.Text.Length > 0)
            {
                txtRightResult.Text = txtRightResult.Text.Remove(0, 2);
            }
