Sure,
I use FileInfo and DirectoryInfo instead of File and Directory so that will
differ in my example. I also use a regular expression to isolate the
extension.
To change the extension: InputString is the original file name, new extension
is "working" in my case, and Expression is (^.+\.)([^?.]+)($)
public string ChangeFileExtention(String InputString, String NewExtention,
String Expression) {
if (InputString.LastIndexOf('.') > 0) {
Regex myExpression = new Regex(Expression);
InputString = Regex.Replace(InputString,
myExpression.ToString(), "$1" + NewExtention);
}
return InputString;
}
copy method:
public void CopyTheFile(String FullPathToFile, String NewPath){
FileInfo myFile = new FileInfo(FullPathToFile);
if (myFile.OpenRead().CanRead) {
myFile.Copy(NewPath + ChangeFileExtention(myFile.Name, "working",
"(^.+\.)([^?.]+)($)");
}
rename method:
public void RenameTheFile(String FullPathToFile){
FileInfo myFile = new FileInfo(FullPathToFile);
if (myFile.OpenRead().CanRead) {
myFile.Copy(NewPath + ChangeFileExtention(myFile.Name, "doc",
"(^.+\.)([^?.]+)($)");
}
Basically I check to make sure I can read the file (not locked) if not I start
copying it. I work with HUGE files so I change the extension so my FileWatcher
doesn't try to try to work with the file before I am done with it. I have the
file watcher looking at a tight mask such as myFile*.doc so the myFile.working
doesn't trigger it. I would first write a method that attempts to copy from
C:\temp to C:\temp\new\ This way you aren't messing with spaces in the file
path and can validate that the copy works. I just coded this in outlook so
don't chastise me if there are a few bugs in the code :-)

Subject: [AspNetAnyQuestionIsOk] Re: File System watcher
I see what you mean. I can get the file to copy but not the shole
thing. So, I kind of follow you in what you are talking about...
name the new file:
file.copy(existingfile, newfile)
well thats really all I have so far but its not coppying the whole
file to the newfile. could you possibly go over the .working scheme
for me a little more in depth?
Thanks,
Eric

start to use it? I wrote a pretty extensive system based on the
file system watcher and ran into that issue. I ended up changing
extensions to .working until I was done copying the file. That way
if my mask was StockInfo_*.dat I wouldn't even see the
TEMP_StockInfo_*.working and simply renamed it when finished. Just
a thought.
