Question

I am using Windows XP. I need to find out the file (in folder D:\Test) with longest path (path length + filename length). How can we find out this using C#?

Is there any command like dir, tree ect for to verify this?
Any idea how to do it using T-SQL?

Note: xp_cmdshell can be used frm T-SQL to get the directory structure

Thanks

Answer 1

Using c# you could use the following snippet to retrieve the file with the longest name:

System.IO.Directory
  .GetFiles("D:\\Test", "*", SearchOption.AllDirectories)
  .OrderByDescending(p => p.Length)
  .FirstOrDefault()

You could validate the output with this PowerShell script:

Get-ChildItem | % { $_.FullName } | Sort-Object -Descending -Property Length

I don’t know how to do this in T-SQL. However, I don’t know why one want to do that.
