How to implement a simple progress bar in WPF?

I was working on a project recently, and I saw that the progress bar written by a former colleague was very effective, so I simplified it. It is not dazzling, but it is still sufficient for the project.

Still, let’s take a look at the effect after the call.

1. Because the Foreground display of ProgressbBar must be the same, there must be a parameter to Control is set, so a parameter value ForegroundColor

public int ForegroundColor {get{return _foregroundColor; }set{ _foregroundColor = value; LinearGradientBrush lgb = dictionary["ForegroundColor" + value] as LinearGradientBrush;if (lgb != null) proBar.Foreground = txt.Foreground = percent.Foreground = lgb; } }

is defined. There is such a sentence in the code "LinearGradientBrush lgb = dictionary["ForegroundColor" + value] as LinearGradientBrush;" for the convenience of passing This is the parameter used to get the style from the style file.

2. Since it is a ProgressBar, it must have a progress value. We use TextBlock to display this value. We must implement the notification interface to ensure real-time notification to the page. superior.

public string ValueText {get{return _valueText; }set{ _valueText = value;if (this.PropertyChanged != null) {this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("ValueText")); } } }

3. Enable a background thread to continuously update the progress effect

private void Bgw_DoWork(object sender, DoWorkEventArgs e) {for (int i = 0; i < BarValue; i++) { System.Threading.Thread.Sleep(50); proBar.Dispatcher.Invoke(new Action( delegate{if (proBar.Value <= BarValue) { proBar.Value++; } })); ValueText = i + ""; } ValueText = BarValue + ""; }
