You're not at all looping the statement, how can that execute multiple times?

Your CopyFile method needs to actually do something.

Solution 2

CopyFile is executed once, of course. If you need a never-ending processing there then you have to use an infinite loop.

infinite loop for Thread??

You don't like infinite loops, do you?

Mahesh Alappuzha 3-Mar-15 6:32am

Thread t = new Thread( () =>
{
while(true)
{
CopyFile()
}
});

t.Start();

LIKE THIS??

Nope. CopyFile should do its useful stuff and terminate. If it must run continuosly (e.g. copying an infinite list of files) then it should implement an infinite loop.

then how it is possible??
this is my CopyFile Function
private void CopyFile ( )
{
string sSourceFolderPath = @"E:\Source";
string sDestinationFolderPath = @"E:\Destination";

DirectoryInfo dDirectoryInfo = new DirectoryInfo ( sSourceFolderPath );
FileInfo[] Files = dDirectoryInfo.GetFiles ( );

foreach ( FileInfo file in Files )
{
string sSourceFileName = file.Name;
string sDestinationFilePath = System.IO.Path.Combine ( sDestinationFolderPath , sSourceFileName );
string sSourceFilePath = System.IO.Path.Combine ( sSourceFolderPath , sSourceFileName );

if ( !System.IO.Directory.Exists ( sDestinationFolderPath ) )
{
System.IO.Directory.CreateDirectory ( sDestinationFolderPath );
}
System.IO.File.Copy ( sSourceFilePath , sDestinationFilePath , true );
}

Thread.Sleep ( 5000 );/* milliseconds to wait */
}

Well, aren't you happy when your function succesfully terminates?
