Small Problem

[JLW]

Here's my variables:
string FileName
string[] tmpSpl
string FilePath

Now, FileName has full path/filename, so, how do I Split FileName at the "\"
char into tmpSpl, then redim preserve tmpSpl by one less, the rejoin it all
into FilePath. I can do this very easily in VB.NET, but can't find anything
on how to do it in C#

Thanks,
JLW

I am not eactly sure what you are trying to do. but you should look in to
the System.IO.Path object.

using System.IO; // at the top

example 1:
string fliename = @"C:\test\mysong.mp3";
Path.GetPathRoot(filename); // c:\test
Path.GetFileName(filename); // song.mp3
Path.ChangeExtension(filename, ".wav"); // c:\test\song.wav
Path.GetDirectoryName(filename); // returns test
Path.GetFileNameWithoutExtention(filename); // returns song

exmple 2:
string path = "c:\test";
string path2 = "c:\test\";
string file = "song.mp3";

Path.Combine(path, file); // returns C:\test\mysong.mp3
Path.Combine(path2, file); // also returns C:\test\mysong.mp3


For you problem I would probably use
string[] rootPath = Path.GetDirectoryName(filename).Split('\\');

Look in .NET docs for:

// join & split
String.Join(...)
string.Split(...)

// redim
Array.Copy(...)

// and
Path.DirectorySeparatorChar

Cheers!

The problem I'm having with split is "\" is a line terminantor char, and I'm
getting just that error. This is all in a function that is being passed the
full path/filename as an argument, and I put a break on the function, and it
doesn't come acrossed as "C:\\path\\file" but "C:\path\file", so that just
isn't working right.

Thanks again,

Try Split("\\")

AFter playing around, this works:
Path.GetDirectoryName(FileName)
Thanks again guys, it was really starting to drive me nutz!

JLW,

Just to let you know when working with strings that have backslashes there
are two ways of doing it.

1. "C:\\test\\somefile.txt";
2. @"C:\test\somefile.txt";

This should help you with some of your escaping issues.

AFter playing around, this works:
Path.GetDirectoryName(FileName)
