C # Multithreading Concurrency Precision Control Example

Online looking for a long time can not find a better example, so I wrote a!

Main demo multi-threading, delegate, callback
Core code:

Public partial class Frmstart:form {#pragma warning disable 0618 public delegate void Addculumcallbac        K (int index,int i);        Public Addculumcallback Addculumcallback;         ManualResetEvent resumeevent = new ManualResetEvent (false);            Public Frmstart () {InitializeComponent ();        Addculumcallback = new Addculumcallback (addculum); } public void Addculum (int index,int i) {This.lvshow.items[index]. SUBITEMS[1].        Text = "Multithreaded concurrent Run Test:" +i.tostring (); private void Btninitil_click (object sender, EventArgs e) {for (int i = 0; i < 3 0;                i++) {ListViewItem LVI = new ListViewItem (""); Lvi.                SubItems.Add (i.ToString ());            THIS.LVSHOW.ITEMS.ADD (LVI);            }} private string GetWebRequest (string url) {uri uri = new uri (URL);   WebRequest myreq = WebRequest.Create (URI);         WebResponse result = Myreq.getresponse (); Stream Recevicestream = result.            GetResponseStream ();            StreamReader Readerofstream = new StreamReader (Recevicestream, System.Text.Encoding.GetEncoding ("Utf-8"));            String strhtml = Readerofstream.readtoend ();            Readerofstream.close ();            Recevicestream.close (); Result.            Close ();        return strhtml;        } private void Btnstart_load (object sender, EventArgs e) {} list<thread> Listthread;            private void Button1_Click (object sender, EventArgs e) {listthread = new list<thread> ();                for (int i = 0; i < i++) {Object index = i;                Thread myThread = new Thread (Method);                Mythread.start (i);            Listthread.add (MyThread); }} public void Method (object index) {String a = GetWebRequest ("HTTp://www.baidu.com "); for (int i = 0; i < 10000; i++) {this.                BeginInvoke (Addculumcallback, index,i);            Thread.Sleep (100); }} private void Btnpausethread_click (object sender, EventArgs e) {foreach (T Hread item in Listthread) {item.            Suspend (); }} private void Btngoahead_click (object sender, EventArgs e) {foreach (Thread item in Li Stthread) {Item.                            Resume (); }} private void btnClose_Click (object sender, EventArgs e) {foreach (Thread item in list Thread) {Item.                            Abort ();                    } listthread.clear ();  }    }
