如何拆分具有相同公共分隔符的字符串 [英] How to split the string having same common delimiters

问题描述

我有一个字符串，我想拆分。我正在从数据库中检索这个字符串。我有大约100个字符串，我正在捕获

例如：

\\C-IMS \IMSData \Images\F1231231\3eb8b6e4-9792-4328-a246-0766e205d0a5.JPG



\\C-IMS \IMSData \Images\F5477748 \97cf42d9-3ed1-4d0c-a26d-098e063871e3.JPG



现在我想将每个字符串拆分为\\C-IMS \IMSData \Images \ F1231231和\C-IMS \IMSData \Images \ F5477748。

Hi ,

I have a string which i want to split.I am retrieving this string from database.I have around 100 strings which i am capturing

\\C-IMS\IMSData\Images\F1231231\3eb8b6e4-9792-4328-a246-0766e205d0a5.JPG

\\C-IMS\IMSData\Images\F5477748\97cf42d9-3ed1-4d0c-a26d-098e063871e3.JPG

Now I want to split each string upto \\C-IMS\IMSData\Images\F1231231 and \C-IMS\IMSData\Images\F5477748.

Thanks in advance

推荐答案

您可以使用LINQ解决这个问题。假设您的字符串存储在IEnumerable或类似字符中，您可以执行以下操作：

You could solve that using LINQ. Assuming your strings are stored in an IEnumerable or similar you could do the following:

// string[] stringCollection = { .. }
var query = from element in stringCollection
            select element.Substring(0, element.LastIndexOf('\\'));

foreach (var item in query)
{
     // Further processing could happen here
}

这里是非linq方式

here is non linq way

string str=@"\\C-IMS\IMSData\Images\F1231231\3eb8b6e4-9792-4328-a246-0766e205d0a5.JPG";

      string str1 = @"\\C-IMS\IMSData\Images\F5477748\97cf42d9-3ed1-4d0c-a26d-098e063871e3.JPG";

        string[] strarr=new string[2];
        strarr[0] = str;
        strarr[1] = str1;
        for (int i = 0; i < strarr.Length; i++)
        {
            string newstr = strarr[i].Substring(0, strarr[i].LastIndexOf('\\'));
            MessageBox.Show(newstr);
        }
