Mycode中发生重复 [英] Duplication is occuring in mycode

问题描述

我的代码有问题.任何人都可以帮助我...

问题:我有两个文本框，一个文本框应接受短语(单词)，另一个文本框应接受数字(1-9)...
如果我在第二个文本框中输入了数字，则应根据文本框编号对gridview中的短语(单词)进行排序.
验证是第一个文本框，不应接受重复的名称或短语.
我已经写过这样的代码，但是它接受重复的名称并在gridview中显示...实际上，它不应接受重复的.....所以请任何人帮帮我.... pls .. ...预先感谢.....

我的代码是这样的:

Hi,

I have a problem in my code.pls can anyone help me...

Problem: I have two textboxes one textbox should accept phrases(words) and another one should accept number(1-9)...

I have written code like this but it is accepting duplicate names and displaying in gridview...actually it should not accept duplicate.....so please can any one help me out.........pls.....Thanks in Advance........

my code is like this:

{
        string phrses = TextBox1.Text;
        string[] split = phrses.Split(',');
        int count = phrses.Length - phrses.Replace(",", "").Length;
        int i = Convert.ToInt32(TextBox2.Text);

        int k1 = 0; int a1 = 0; int b = 0;
        for (a1 = count; a1 > 0; a1--)
        {
            for (b = count; b > 0; b--)
            {
                if (a1 != b)
                {
                    if (split[a1] == split[b])
                    {
                        k1 = 1;
                    }
                }
            }
        }
        if (k1 != 0)
        {
            Response.Write("enter different phrases");
        }
        string[] splichar = new string[split.Length];
        int j = 0;
        foreach (string a in split)
        {
            splichar[j] = a.Substring(i - 1);
            j++;
        }
        Array.Sort(splichar);

        j = 0;
        foreach (string k in splichar)
        {
            foreach (string p in split)
            {
                if (p.Contains(k))
                {
                    splichar[j] = p;
                }
            }
            j++;
        }

推荐答案

可以检查在给定的单词组separated by ,中是否重复了word or phrase使用LINQ或Regex 如下所示:

It can be checked whether a word or phrase is repeated in the given group of words separated by , either using LINQ or Regex as shown below:

string words1 = "abcd,defgh xyz, abcd, defgh, abcd,  abcd, ijkl";
string words2 = "abcd,defgh xyz,  ijkl, mnop, qrst, uvw, abc, uvws, defghxyz";
int max = words1.Split(',').Select (w => w.Trim())
                .GroupBy (w => w).Max (w => w.Count ());
Console.WriteLine (max);

bool result = Regex.IsMatch(words1,
                @"(?:^\s*(?<word>[^,]+)\s*,|,\s*(?<word>[^,]+)\s*,)"+
                @"(?=.*,\s*\k<word>\s*,|.*,\s*\k<word>\s*

)"， RegexOptions.CultureInvariant | RegexOptions.IgnoreCase); Console.WriteLine(结果); // words1的输出 // 4 // 真实 // words2的输出 // 1 // 错误

)", RegexOptions.CultureInvariant | RegexOptions.IgnoreCase); Console.WriteLine (result); //Output for words1 //4 //True //Output for words2 //1 //False

我不确定我是否完全理解代码.这行似乎很奇怪:

I am not sure I totally understand the code. This line seems strange:

int count = phrses.Length - phrses.Replace(",", ";").Length;

原因是替换"不应更改长度，因此计数应始终为零.您调试了吗?

The reason is that the Replace should not change the length, so the count should always be zero. Did you debug this?
