c# service renaming files!

I have a windows service , that takes files with metadata(FIDEF) and corresponding video file and , translates the XML(FIDEF) using XSLT .

I get the file directory listing for FIDEF's and if a video file of the same name exists it translates it. That works ok , but it is on a timer to search every minute. I am trying to handle situations where the same file name enters the input directory but is already in the output directory. I just have it changing the output name to (copy) thus if another file enters i should get (copy)(copy).mov but the service won't start with filenames of the same directory already in the output , it works once and then does not seem to pick up any new files.

Any Help would be great as I have tried a f开发者_开发问答ew things with no good results. I believe its the renaming methods, but I've put most of the code up in case its a clean up issue or something else. (forgive some of the names just trying different things).

There is a lot wrong with your code. getFileList has the unneeded inner for loop for starters. Get rid of it. Your foreach loop has s, which can replace filepaths[i] from your for loop. Also, don't do outputPath + result to make file paths. Use Path.Combine(outputPath, result) instead, since Path.Combine handles directory characters for you. Also, you need to come up with a better name for getFileList, since that is not what the method does at all. Do not make your method names liars.

I would simply get rid of MoveVideoFiles. The compiler just might too.

GetUniqueName only works if your file name is of the form name.mov.fidef, which I'm assuming it is. You really need better variable names though, otherwise it will be a maintenance nightware later on. I would get rid of the == true in the while loop condition, but that is optional. The assignment inside the while is why your files get overwritten. You always generate the same name (something(Copy).mov.fidef), and as far as I can see, if the file exists, I think you blow the stack looping forever. You need to fix that loop to generate a new name (and don't forget Path.Combine). Maybe something like this (note this is untested):

int copyCount = 0;
while (File.Exists(ValidName))
{
    const string CopyName = "(Copy)";
    string copyString = copyCount == 0 ? CopyName : (CopyName + "(" + copyCount + ")");
    string tempName = Justname + copyString + Extension2 + Extension;
    ValidName = Path.Combine(outputPath, tempName);
    copyCount++;
}

This generates something(Copy).mov.fidef for the first copy, something(Copy)(2).mov.fidef for the second, and so on. Maybe not what you want, but you can make adjustments.

At this point you have a lot to do. getMovFile looks as though it could use work in the same manner as GetUniqueName. You'll figure it out. Good luck.
