搜索目录C＃中的文件 [英] search files in directory C#

问题描述

我需要在一个目录中找到一个文件，里面有很多文件夹。



我写了一个代码来执行它，因为目录有更多其中包含1000个文件夹，获取结果需要更多时间。



我的代码：

I need to find a file within a directory which has lot many folder within it.

I have written a code which does it, since the directory has more than 1000 folders in it, it takes more time to fetch the result.

My code :

protected void Button1_Click(object sender, System.EventArgs e)
   {
       string search = TextBox1.Text;
       string[] files = Directory.GetFiles(@"\\directory1\storage\folder1\", "*.*", SearchOption.AllDirectories);
       int Flag = 0;
       string dir = @"\\directory1\storage\folder1\";
       string[] files1;
       int numFiles;
       files1 = Directory.GetFiles(dir);
       numFiles = files.Length;
       Response.Write("Files searched : " + numFiles + "<br>");
       for (int i = 0; i < numFiles; i++)
       {


           string file = files[i].ToString();

           int file1 = file.IndexOf(search,StringComparison.CurrentCultureIgnoreCase);
           if (file1 != -1)
           {
               Response.Write("<br>" + file);
               //Response.Write("<div style='position:absolute;top:" + file + "px;left:" +  "px'>"+file! + "</div>");
               Flag = 1;

           }




       }
       if (Flag == 0)
       {
           Response.Write("No Matches Found");
       }
   }

请建议我，可能会发布代码。

Kindly suggest me, possibly post the code.

推荐答案

方法 Directory.GetFiles 有一个令人讨厌的警告，但不是很清楚。



请参阅此讨论（以及我的回答）;你会找到确切的固定解决方案： Directory.Get.Files搜索模式问题 [ ^ ]。

The method Directory.GetFiles has one nasty caveat which is not very well know.

Please see this discussion (and my answer, too); you will find exact fixed solution: Directory.Get.Files search pattern problem[^].

我认为你可以提供搜索字符串Directory.GetFiles本身。喜欢（Myfile * .txt或MyFile.txt）。不知道这是否会提高速度。试试吧。:)

I think you can provide search string in Directory.GetFiles itself. like ( Myfile*.txt or MyFile.txt ). Don't know whether this will improve the speed. Just try .:)

根据您的要求，我知道您要搜索文件夹中的特定文件，包括子文件夹。



你可以这么简单..

As per your requirement, i understood you want to search a specific file in the folder including sub folders.

you can you simple like this..

string[] files = Directory.GetFiles("c:\\", "*.exe", SearchOption.AllDirectories);

希望这可以帮到你
