code for searching files using single word key is as follows:

string s = "", s1 = ""; //to get the file name
               // string files = "";
               string filename = "*" + tb_search.Text + "*";
               DirectoryInfo MyDir;
               ArrayList CellarList = new ArrayList();
               MyDir = new DirectoryInfo(Server.MapPath("files/"));
               string path = (Server.MapPath("files/"));
               //FileInfo[] MyFiles = MyDir.GetFiles("*.*");
               string[] fileList = System.IO.Directory.GetFiles(path, filename);

               foreach (string file in fileList)
               {
                   if (file.ToLower().Contains(tb_search.Text.ToLower().ToString()))
                   {
                       s = file.ToString();
                       s1 = s.Replace(path, "");
                       lb_search.Items.Add(s1);
                   }
               }

谁能帮我...
在此先感谢

答

根据您的代码，您正在尝试在给定目录中搜索文件名.，

为此，您可以使用以下代码.

As per your code, you are trying to search the file names in the given directory .,

for this you can use the below code.

string[] files = Directory.GetFiles(Server.MapPath("files/"), "*.*");

第二个参数可以是任何通配符.

例如:

Second Argument can be any wild card.

Ex :

string[] files = Directory.GetFiles(Server.MapPath("files/"), "A*.*");

文件以"A"开头

files start with "A"

string[] files = Directory.GetFiles(Server.MapPath("files/"), "ABC?.*");

文件以"ABC"开头，并以任何字符结尾.

Files Start with "ABC" and ends with any character.

string[] files = Directory.GetFiles(Server.MapPath("files/"), "ABC DEF*.*");

文件以"ABC DEF"开头，并以任何字符结尾.

希望对您有帮助.

Files Start with "ABC DEF" and ends with any characters.

Hope this helps you.
