You can try this code to search files in the directory:

public static void disp(string source)
    {

        DirectoryInfo dr = new DirectoryInfo(source);

        DirectoryInfo dir = new DirectoryInfo(des);

        foreach (FileInfo fs in dr.GetFiles())
        {

            path = fs.Extension;

            switch (path)
            {

                case ".doc":

                    if (!Directory.Exists("DOC"))
                    {

                        dir.CreateSubdirectory("DOC");

                    }



                    Console.WriteLine("file" + fs.Name);

                   

                    break;

                case ".txt":

                    if (!Directory.Exists("txt"))
                    {

                        dir.CreateSubdirectory("txt");

                    }



                    Console.WriteLine("file" + fs.Name);

                    

                    break;

                case ".pdf":

                    if (!Directory.Exists("txt"))
                    {

                        dir.CreateSubdirectory("txt");

                    }



                    Console.WriteLine("file" + fs.Name);

                    

                    break;

            }



        }
    }

Solution 1

C#

//string filename = TextBox1.Text;
 if (File.Exists(Server.MapPath("Image/untitled.png")))
     // if (File.Exists(Server.MapPath(filename)))

     Response.Write("file exist");
 else
 {
     Response.Write("no");
 }

here "Image" is folder in solution and "untitled.png" is file in this folder and i am able to get this. I think in text box you are not getting correct file path.

can u do me a favor .....
sorry for disturbing u...

i need to display list of files from remote server which has the keyword i specify in a textbox. and also need to see that file when double cliked on it.
which control should i use to display the list...if i use listbox, i think there is no double click event.
i tried your code :-

string filename = TextBox1.Text;
if (File.Exists(Server.MapPath("files/" + (filename))))
{
Response.Write("file exist");
ListBox1.Items.Add(filename);

}
else
{
Response.Write("no");
}

here file is the folder name,
the above shows only single file, and it is displayed only when the complete name is inputed.

can you plz help me...
thanks in advance...
