C# (how to mach file names with different extensions....??)

Each file is processed and get a .wav file in this program.  I need to copy only the filenames that match to a .wav file in a folder.  I know this is easy, but I am converting from VB.NET to C# and the language is not the same.  I need this done fast apparently.  I need a few gallons of coffee at this point.

Thanks in advance,

string sourcePath = ConfigurationManager.AppSettings["DictaphoneChild"].ToString() + "\\" + fileName;
                    string targetPath = ConfigurationManager.AppSettings["Dictaphone"].ToString() + "\\" + fileName;

                    string[] files = System.IO.Directory.GetFiles(sourcePath);

                    // Copy the files and overwrite destination files if they already exist.
                    foreach (string s in files)
                        // Use static Path methods to extract only the file name from the path.
                        fileName = System.IO.Path.GetFileName(s);
                        // code for only wav files that match file name XML.

                        string destFile = System.IO.Path.Combine(targetPath, fileName);
                        System.IO.File.Copy(s, destFile, true);

You have something.wav
and you want just "something"?!

make a method that takes filename as argument and returns string without extension.

string newFile = filename.Substring(0, filename.LastIndexOf("."));
Sounds to me like you are only looking for .wav files.  If that is correct the following will work.

string[] files = System.IO.Directory.GetFiles(sourcePath, "*.wav");
try this function
bool CompareJustFileName(string strFile1, string strFile2)
	int index1 = strFile1.LastIndexOf("\\");
	if(index1 == -1)
		index1 = 0;

	int index2 = strFile2.LastIndexOf("\\");
	if(index2 == -1)
		index2 = 0;

	int comp = strFile1.Substring(index1, strFile1.LastIndexOf(".")).CompareTo(strFile2.Substring(index2, strFile2.LastIndexOf(".")));

	return (comp==0);

The files in the directory look like this:

They want to move Text1.xml, Text2.xml and Text1.wav,Text2.wav to a different directory, leaving text.xml in the original folder.  I am sort of sleepy(work, work, work), and I have spend too much time trying to get this to work.  I know that answer is simple it should be after I get the file name I just don't know th comman in C# to hunt down the Text1.xml, Text1.wav and copy it to another directory.  The copy part I know how to do it is the matching if there is a .wav file.      
How about something like this

string sourceDir = ConfigurationManager.AppSettings["DictaphoneChild"].ToString();
            string targetDir = ConfigurationManager.AppSettings["Dictaphone"].ToString();

            string[] wavFiles = Directory.GetFiles(sourceDir, "*.wav");

            foreach (string wavFile in wavFiles)
                string wavFileName = Path.GetFileName(wavFile);
                string xmlFileName = Path.GetFileNameWithoutExtension(wavFile) + ".xml";

                string targetWavFileName = Path.Combine(targetDir, wavFileName);
                string targetXmlFileName = Path.Combine(targetDir, xmlFileName);

                File.Copy(wavFile, targetWavFileName);
                File.Copy(xmlFileName, targetXmlFileName);

It seems to me that you should search for all ".xml" files in "sourceDir" and then only move those files having a matching ".wav" file:
            string sourcePath = ConfigurationManager.AppSettings["DictaphoneChild"].ToString() + "\\" + fileName;
            string targetPath = ConfigurationManager.AppSettings["Dictaphone"].ToString() + "\\" + fileName;

            string wavFile;
            string[] xmlFiles = System.IO.Directory.GetFiles(sourcePath, "*.xml");
            foreach (string xmlFile in xmlFiles)
                wavFile = System.IO.Path.Combine(sourcePath, System.IO.Path.GetFileNameWithoutExtension(xmlFile) + ".wav");
                if (System.IO.File.Exists(wavFile))
                    System.IO.File.Copy(xmlFile, System.IO.Path.Combine(targetPath, System.IO.Path.GetFileName(xmlFile)), true);
                    System.IO.File.Copy(xmlFile, System.IO.Path.Combine(targetPath, System.IO.Path.GetFileName(wavFile)), true);

This is for MarshalMooreman, because you are on the right track!  

I get an error stating it cannot find the .xml file when tried your solution.  It fails on the last line.  

File.Copy(xmlFileName, targetXmlFileName);

I assure you the file is there.  Other than that, it is working smoothly.

After being up all night writing code, this person was a real help.  I am still trying to convert my VB.NET skills to C#.  I think I can get some sleep after this intervention.  Words cannot decribe how much I appreciate the help!
