ProgressChangedEventArgs.ProgressPercentage Property

Gets the asynchronous task progress percentage.

Namespace: System.ComponentModel
Assembly: System (in system.dll)

public int ProgressPercentage { get; }
/** @property */
public int get_ProgressPercentage ()

public function get ProgressPercentage () : int

Not applicable.

Property Value

A percentage value indicating the asynchronous task progress.

The ProgressPercentage property determines what percentage of an asynchronous task has been completed.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the PictureBox.LoadProgressChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing System.Windows.Forms.MessageBox.Show with System.Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type PictureBox named PictureBox1. Then ensure that the event handler is associated with the PictureBox.LoadProgressChanged event.

private void PictureBox1_LoadProgressChanged(Object sender, ProgressChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ProgressPercentage", e.ProgressPercentage );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "UserState", e.UserState );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "LoadProgressChanged Event" );
}
