Question

I am having a list box on my form what i need is i would like to display all the text files that are presented in the local drives to that list box on Form Load can any one help me.

I wrote my code like this

string[] filepaths;
filepaths = Directory.GetFiles(@"c:\", "*.txt", SearchOption.AllDirectories);

But this is throwing an error how can i read the files from all directories

Answer 1

Something like this:

string drivePath = @"C:\";

var textFiles = Directory.GetFiles(drivePath, "*.txt", SearchOption.AllDirectories);
listBox1.DataSource = textFiles;

notice that a recursive walk of an entire drive can take a long time…

EDIT:

To avoid access denied problem, instead of Directory.GetFiles() you can use the code given in this answer :

string drivePath = @"C:\";

var textFiles = GetFiles(drivePath, "*.txt").ToList();
listBox1.DataSource = textFiles;
