Multithreading: how to create different threads (which all do the same job) but with different parameters ??

Hi there,

Basically I am a bit confusing about multithreading...I have created this class ThreadJob that holds the work that every thread has to do, which basically is copying files from one directory to another. I try to create different threads as follows :

class Program

class ThreadJob

int iJobId;

Boolean bDone;

string szFromPath;

string[] szToPath;

int iThreadId;

int iId = 1;

string szError = "";

public ThreadJob(int jobId, string fromPath, string[] toPath)

bDone = false;

iId++;

}

public int ThreadId

get { return (iThreadId); }

public Boolean Done

get { return (bDone); }

public String Error

get { return (szError); }

public void Start()

//Do the copying

try

//Check if the scan directory exists

DirectoryInfo di = new DirectoryInfo(szFromPath);

if (di.Exists)

FileInfo[] files = di.GetFiles();

foreach (FileInfo fi in files)

bool bError = false;

foreach (string dup in szToPath)

//Check that the directory exists

DirectoryInfo dir = new DirectoryInfo(dup);

if (dir.Exists)

//Try copying the files

try

catch (Exception ex)

szError += "Error copying file \"" + fi.Name + "\" to directory \"" + dup + "\".Reason: " + ex.ToString() + Environment.NewLine;

bError = true;

else

szError += "Copying directory \"" + dup + "\" does not exists" + Environment.NewLine;

break;

if (bError == false)

//There were no errors copying file to all dups. Delete it

else

szError += "Finished copying files from \"" + szFromPath + "\". There were errors copying the files from this directory." + Environment.NewLine;

else

szError += "Scan directory \"" + szFromPath + "\" does not exists" + Environment.NewLine;

catch (Exception ex)

szError += "Error copying files from \"" + szFromPath + "\". Reason: " + ex.ToString() + Environment.NewLine;

finally

bDone = true;
