windows service help

[CK]

I need a windows service that listens to a directory , if any xml file is
placed in the directory it reads it and calls a class and receives a
string.. this is the code I came up with. it works but it kills my processor
after a few min. what should i do??

Thanks

private void button6_Click(object sender, System.EventArgs e)

{

NewClaims.clsNewClaims objNewClaimI = new NewClaims.clsNewClaims();

while (true)

{

//Get the File in the directory

DirectoryInfo dir = new DirectoryInfo(@"C:\test4");

FileInfo[] xmlfiles = dir.GetFiles("*.xml");

foreach( FileInfo file in xmlfiles)

{

string strHMI="";

//Opens an existing UTF-8 encoded text file for reading.

StreamReader sr = File.OpenText(file.FullName);

string data= sr.ReadToEnd();
strHMI = objNewClaimI.ConvertNewClaimsXmlUICIToHMItxt(data) ;

int intExtension=file.Name.IndexOf(".");

FileInfo outputFile = new
FileInfo(@"c:\test5\"+file.Name.Substring(0,intExt ension)+".txt");

StreamWriter strWriter =new StreamWriter(File.Open(@"c:\test5\" +
file.Name.Substring(0,intExtension) +".txt",FileMode.Create,
FileAccess.Write ));

strWriter.Flush();

strWriter.Write(strHMI.ToString());
strWriter.Close();

sr.Close();

file.Delete();

}
}

Hi CK

You should try using the FileSystemWatcher component. This does exactly what
you want. Your code seems to be in a tight loop, hence the problem! With the
FileSystemWatcher, you get a notification when a file addition (or
modification or deletion) occurs in the watched directory.

I agree that FileSystemWatcher is what you want to use, but if that
doesn't work for you (whatever the reason) you could put this operation
in a separate thread and be sure to call Thread.Sleep() periodically.

I tried FileSystemWatcher but it wont work when I insert a file into the
directory. it works only when I change something in the file, delete the
file. its basicly changes within the directory not adding a file into the
directory.
I did try the treading and its better except I dont know where in the code i
should try the tread.sleep() method.
