Simply reading a filename

[John Duval]

Hi Petrosky,
I'm not sure exactly what you're looking for -- do you want the user to
browse for a file on the system using a GUI? If so, then check out the
OpenFileDialog class. For example:

OpenFileDialog ofd = new OpenFileDialog();
DialogResult dr = ofd.ShowDialog();
if (dr == DialogResult.OK)
{
string filename = ofd.FileName;
MessageBox.Show(filename);
}

Sounds like your looking to find a the location of a file given the name

If so, then you could simply recursively search the drives, checking for
filenames that match.

If you want to check that a file/directory exists then you can use the File
class:

using System.IO;

if (File.Exists(@"c:\test.dat"))...
if (Directory.Exists(@"c:\myfolder"))...

If you want information on the file (size, modify time etc.) then take a
look at the FileInfo class:

FileInfo fi = new FileInfo(@"c:\test.dat");
fi.Length

Petrosky,

I think you are looking for System.IO.Directory.GetFiles. This method can
look for files using wildcards.

Hello,
May I ask what built-in functions available out there in C# to search
for a particular filename input from the user at runtime ?
I am completely new to system thingies, so please help beginner. I
appreciate any answers from you.
