[英]How To: Convert anonymous method to VB.NET
我在C#中有以下內容:
public static void StartAnimation(UIElement animatableElement, DependencyProperty dependencyProperty, double toValue, double animationDurationSeconds, EventHandler completedEvent)
{
double fromValue = (double)animatableElement.GetValue(dependencyProperty);
DoubleAnimation animation = new DoubleAnimation();
animation.From = fromValue;
animation.To = toValue;
animation.Duration = TimeSpan.FromSeconds(animationDurationSeconds);
//// HERE ----------------------------------------------------
animation.Completed += delegate(object sender, EventArgs e)
{
//
// When the animation has completed bake final value of the animation
// into the property.
//
animatableElement.SetValue(dependencyProperty,
animatableElement.GetValue(dependencyProperty));
CancelAnimation(animatableElement, dependencyProperty);
if (completedEvent != null)
{
completedEvent(sender, e);
}
};
我有一些問題將匿名方法轉換為VB.NET。
我的變體是
AddHandler animation.Completed,
Function(sender As Object, e As EventArgs) As Boolean
' '
' When the animation has completed bake final value of the animation '
' into the property. '
'
animatableElement.SetValue(dependencyProperty, animatableElement.GetValue(dependencyProperty))
CancelAnimation(animatableElement, dependencyProperty)
completedEvent(sender, e)
Return True
End Function
我添加了Function As Boolean
因為沒有返回類型不是函數,但是制作“子”我不知道如何...
一些忠告?
匿名方法的語法如下:
AddHandler animation.Completed, _
Sub(sender As Object, e As EventArgs)
' '
' When the animation has completed bake final value of the animation '
' into the property. '
'
animatableElement.SetValue(dependencyProperty, animatableElement.GetValue(dependencyProperty))
CancelAnimation(animatableElement, dependencyProperty)
completedEvent(sender, e)
End Sub
但是,你需要VB10才能使用它,以前的版本還不支持這個。
把它變成SUB。
Public SUB <method name>(<parameters>)
'Body of the method
