Question

My origanl DoWork Method was:

private static void DoWork(string dirPath)

which I called from my Main Method using:

DoWork(@"C:\location");

But I’ve changed the DoWork method to the following.

private static void DoWork(string sourceDir, string fileType)

I’m stumped how to call this from my main method, I am new to c# and have looked at the MSDN site but for some insight but I can’t seem to find anything to relate to my issue. Any guidance would be appreciated.

Snippet from my DoWork method:

    private static void DoWork(string sourceDir, string fileType)
    {

        // Function: Get specified files (fileType) form sub-directory (sourceDir)
        // Return: void
            {
    string[] dirEntries = Directory.GetDirectories(@"c:\fileDump");
    string fileName, filePath, fullFileName;

    foreach (string subDir in dirEntries)
{
    DirectoryInfo dir = new DirectoryInfo(subDir);
    FileInfo[] imgFiles = dir.GetFiles("*.xml");

    foreach (FileInfo imgFile in imgFiles)
{
    fileName = imgFile.Name;
    filePath = imgFile.DirectoryName;
    fullFileName = "filePath + “\\” + fileName";

Answer 1

So, I suppose, you want to call a method that works only on certain kind of files.
Then your code should be something like this

 private static void DoWork(string sourceDir, string fileType)
 {
      string[] fileEntries = Directory.GetFiles(sourceDir, fileType, 
                             SearchOption.AllDirectories);
      foreach (string fullFileName in fileEntries)
      {
            ....
      }
 }

and call it from the Main method in this way

 // Work on every JPG file in source location and subdirectory of the initial location
 DoWork(@"c:\location", "*.jpg");

The Directory.GetFiles method could take three arguments that specify the source location, the file pattern to match files and an enum that triggers a recursive search of all subfolders of the initial folder.
