Multithreading a windows application

This is my loop it calls GetFileVoters2012(Phone) that function needs to be multi-threaded. Your bid needs to included time test and confirm code. private void processVoter2012() { Int64 ID = 0; string Phone = ""; SqlConnection cn = new SqlConnection([login to view URL]); SqlCommand cmd = new SqlCommand("usp_SelectVoters2012PhoneNumbers", cn); [login to view URL] = [login to view URL]; [login to view URL]("@City", [login to view URL]); [login to view URL] = 0; [login to view URL](); SqlDataReader dr = [login to view URL](); while ([login to view URL]()) { Phone = [login to view URL]([login to view URL]("Phone")); // Thread t = new Thread(()=>GetFileVoters2012(Phone)); // Kick off a new thread // [login to view URL](); // [login to view URL](1000); GetFileVoters2012(Phone); } [login to view URL](); } public void GetFileVoters2012(string Phone) { string npa="",qnxx="",qstation=""; if ([login to view URL] == 7) Phone = "954" + Phone; if ([login to view URL] == 10) { npa = [login to view URL](0, 3); qnxx = [login to view URL](3, 3); qstation = [login to view URL](6, 4); string strURL = "[login to view URL]" + npa + "&qnxx=" + qnxx + "&qstation=" + qstation + "&focusfirst=1"; string Listofphone = "", phone = "", tst = "", PhoneType = ""; Int32 i = 0; double num; Boolean isNum; try { WebRequest myWebRequest = [login to view URL](strURL); WebResponse myWebResponse = [login to view URL](); Stream ReceiveStream = [login to view URL](); Encoding encode = [login to view URL]("utf-8"); StreamReader readStream = new StreamReader(ReceiveStream, encode); string strResponse; while ((strResponse = [login to view URL]()) != null && PhoneType=="") { /* StreamWriter oSw = new StreamWriter(strFilePath); [login to view URL](strResponse); [login to view URL](); [login to view URL](); */ i = [login to view URL]("Land Line"); if (i > 0) PhoneType = "L"; i = [login to view URL]("Cellular"); if (i > 0) PhoneType = "C"; i = [login to view URL]("Paging"); if (i > 0) PhoneType = "P"; } [login to view URL](); } catch { } [login to view URL] = Phone + "- " + PhoneType; [login to view URL](); SqlConnection conn = new SqlConnection([login to view URL]); SqlCommand cmd = new SqlCommand("usp_InsertVoters2012PhoneType", conn); [login to view URL] = [login to view URL]; //save ROS // [login to view URL]("@Phone", ID); [login to view URL]("@Phone", Phone); [login to view URL]("@PhoneType", PhoneType); [login to view URL](); [login to view URL](); [login to view URL](); } }
