C# - Search for Matching FileNames in a Directory using SearchOption
Background: I'm developing a WinForms application using C# with an OpenFileDialog & FileBrowserDialog that will 1) search for a specific string in the filenames of a specified source directory 2) copy files to consolidated directory 3) convert multiple files from excel to csv files, and then 3) convert all the generated csv files into 1 big csv file using a command line executable
Example: MSDN provides a code example that lists all of the directories and files that begin with the letter "c" in "c:\". at http://msdn.microsoft.com/en-us/library/ms143448.aspx so I based my code on that...
Problem: The code doesn't copy any files to the consolidated folder so I'm pretty sure the search doesn't work.
What should I change on here? It doesn't work :
string files = "*.xlsx";
void DirSearch(string sDir)
{
try
{
foreach (string d in Directory.GetDirectories(sDir))
{
foreach (string f in Directory.GetFiles(d, files))
{
// Is this the file we are looking for?
// check excel files for corp name in the filename.
if (f.Contains(m_sc.get_Corp()))
{
// check if thread is cancelled
if (m_EventStop.WaitOne(0, true))
{
// clean-up operations may be placed here
// ...
// inform main thread that this thread stopped
m_EventStopped.Set();
return;
}
else
{
string path = sDir;
string searchPattern = m_sc.get_Corp();
// A file has been found in this directory
DirectoryInfo di = new DirectoryInfo(path);
DirectoryInfo[] directories = di.GetDirectories(searchPattern, SearchOption.TopDirectoryOnly);
foreach (FileInfo file in files)
{
try
{
// Copy each selected xlsx files into the specified TargetFolder
System.IO.File.Copy(FileName, consolidatedFolder + @"\" + System.IO.Path.GetFileName(FileName));
Log("File" + FileName + " has been copied to " + consolidatedFolder + @"\" + System.IO.Path.GetFileName(sourceFileOpenFileDialog.FileName));
// Convert each selected XLSX File to CSV Using the command prompt code...
}

The code you've posted does two separate search loops:
first:
foreach (string d in Directory.GetDirectories(sDir))
{
foreach (string f in Directory.GetFiles(d, files))
{
// Is this the file we are looking for?
// check excel files for corp name in the filename.
if (f.Contains(m_sc.get_Corp()))
{
then within that it also does: string path = sDir; string searchPattern = m_sc.get_Corp();
// A file has been found in this directory
DirectoryInfo di = new DirectoryInfo(path);
DirectoryInfo[] directories = di.GetDirectories(searchPattern, SearchOption.TopDirectoryOnly);
foreach (FileInfo file in files)
{
In the first one you are looking for files matching m_sc.get_Corp();
, in the second one you are lookinf for directories...
In fact... your code (pseudo-code?) makes no sense...
Try:
- taking your time
- tidying up the code yourself
- if you rewrite it slowly and break this into smaller chunks, you might spot what you are doing wrong.
Try cleaning up a bit, below is some code that will put you on the path, I've excluded the CSV conversion and the merge, hopefully you will get the idea.
private void YourFileRoutine(string sourceDirectoryPath, string consolidatedDirectoryPath)
{
var excelFiles = new DirectoryInfo(sourceDirectoryPath).GetFiles().Where(x => x.Extension == ".xlsx");
//Copy all Excel Files to consolidated Directory
foreach (var excelFile in excelFiles)
{
FileInfo copiedFile = excelFile.CopyTo(String.Concat(consolidatedDirectoryPath, excelFile.Name)); // Make sure consolidatedDirectoryPath as a "\" maybe use Path.Combine()?
// ConvertToCSV( Do your CSV conversion here, the Path will be = Path.GetFullPath(copiedFile);
}
// Merge CSV's
var csvFiles = new DirectoryInfo(consolidatedDirectoryPath).GetFiles().Where(x => x.Extension == ".csv");
// SomeMergeMethod that iterates through this FileInfo collection?
}
