hey guys,
i am looking at this piece of code that lists numbers of files in a
directory. i want to convert it so it lists the files in th directory that
end with .doc. i cant seem to get it to output correctly, i have included
the original code, my modified code, and the output from my modifed code..
why does it list the files as "System.IO.FileInfo[]"???
thanks

using System;

class Test

DirectoryInfo[] dirs = di.GetDirectories("*p*");
Console.WriteLine("Number of directories with a p: {0}",
dirs.Length);
// Count all the files in each subdirectory that contain the

Do this..
string[] files = System.IO.Directory.GetFiles("D:\\WINDOWS", "*.doc");

How do you want .net to create a string that "represents" a reference to an
array?
The default way to do this is to print out the type, which is what you are
getting. If you want to print out the actual contents, then you will need
an inner loop to scan through the array, get the file names, and print them
out.

After looking at the code he has posted ... I wonder.. there are other

since he is not worried about recursively navigating through the

//System.Collections.ArrayList files = new

foreach (string dir in System.IO.Directory.GetDirectories("c:\\", "*p*"))

Hello Champika,
I believe that the OP's code did not reflect his intent. He complained
about not getting the names of the files, which leads me to believe that he
actually wants to see the names of the files. Your code will get him to the
place he is at, more succinctly, but I do not believe that it is the place
he wants to be at.

news:4Y********************@comcast.com... Hello Champika,
I believe that the OP's code did not reflect his intent. He complained
about not getting the names of the files, which leads me to believe that
he actually wants to see the names of the files. Your code will get him to
the place he is at, more succinctly, but I do not believe that it is the place
he wants to be at.

news:es********************@comcast.com... because this line is not good:
foreach (DirectoryInfo diNext in dirs)
{
Console.WriteLine(diNext.GetFiles("*.doc"));
}
diNext.GetFiles() will return an array of files that matches the expression. How do you want .net to create a string that "represents" a reference
to an array?
The default way to do this is to print out the type, which is what
you are getting. If you want to print out the actual contents, then you will need an inner loop to scan through the array, get the file names, and print
them out.
After looking at the code he has posted ... I wonder.. there are other
better ways of doing this..
since he is not worried about recursively navigating through the
subdirectories..
//System.Collections.ArrayList files = new
System.Collections.ArrayList();
foreach (string dir in System.IO.Directory.GetDirectories("c:\\",
"*p*")) {
//files.AddRange(System.IO.Directory.GetFiles(dir, "*.txt"));
Console.WriteLine("The number of files in {0} with an e is {1}", dir,
System.IO.Directory.GetFiles(dir, "*.txt").Length);
}
may do what he need..
Nirosh.
