Answer 1

string name = textBox2.Text;
string[] allFiles = System.IO.Directory.GetFiles("C:\\");//Change path to yours
foreach (string file in allFiles)
    {
        if (file.Contains(name))
        {
            MessageBox.Show("Match Found : " + file);
        }
    }

Answer 2

G'day,

Here's the approach I used. You'll need to add a textbox (txtSearch) and a button (cmdGo) onto your form, then wire up the appropriate events. Then you can add this code:

    private void cmdGo_Click(object Sender, EventArgs E)
    {
        //  txtSearch.Text = "*.docx";

        string[] sFiles = SearchForFiles(@"C:\Documents and Settings\Admin\Desktop\test", txtSearch.Text);
        foreach (string sFile in sFiles)
        {
            Process.Start(sFile);
        }
    }

    private static string[] SearchForFiles(string DirectoryPath, string Pattern)
    {
        return Directory.GetFiles(DirectoryPath, Pattern, SearchOption.AllDirectories);
    }

This code will go off and search the root directory (you can set this as required) and all directories under this for any file that matches the search pattern, which is supplied from the textbox. You can change this pattern to be anything you like:

• *.docx will find all files with the extention .docx
• *foogle* will find all files that contain foogle

I hope this helps.

Cheers!
