BackgroundWorker application, backgroundworker

BackgroundWorker can be used to control the progress of a progress bar.

BackgroundWorker bWork = new BackgroundWorker ();

 

BWork. workersuppscanscancellation = true; // The setting can be canceled.
BWork. WorkerReportsProgress = true; // whether to report the progress

Then there are two events. dowork executes the operation,

// Accept progress and set progress bar
Void bWork_ProgressChanged (object sender, ProgressChangedEventArgs e) {this. progressBar1.Value = e. progressPercentage;} void bWork_DoWork (object sender, DoWorkEventArgs e) {int I = 0; while (I <= 100) {if (bWork. cancellationPending) {e. cancel = true; break;} bWork. reportProgress (I ++); // report progress Thread. sleep (100 );}}
