You do not need to create a event handler for this. Just add to the Styleof your Buttonthis trigger:
您不需要为此创建事件处理程序。只需添加到Style您的Button此触发器中：
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Cursor" Value="Wait" />
</Trigger>
</Style.Triggers>
</Style>
Besides, the Cursor and the Mouse event is related to a View. This means that it is desirable to do this action in not the ViewModel, and do it on the side of View.
此外，Cursor 和 Mouse 事件与View. 这意味着最好在不做这个动作ViewModel，并在旁边做View。

To change the cursor, you can use Mouse.OverrideCursor Property
要更改光标，您可以使用 Mouse.OverrideCursor Property
private void CursorTypeChanged(object sender, SelectionChangedEventArgs e)
{
Mouse.OverrideCursor = Cursors.Wait;
}
Then to reset, you can use :
然后要重置，您可以使用：
Mouse.OverrideCursor = null;
another example (from msdn)
另一个例子（来自msdn）
// Determines the scope the new cursor will have.
//
// If the RadioButton rbScopeElement is selected, then the cursor
// will only change on the display element.
//
// If the Radiobutton rbScopeApplication is selected, then the cursor
// will be changed for the entire application
//
private void CursorScopeSelected(object sender, RoutedEventArgs e)
{
RadioButton source = e.Source as RadioButton;
if (source != null)
{
if (source.Name == "rbScopeElement")
{
// Setting the element only scope flag to true
cursorScopeElementOnly = true;
// Clearing out the OverrideCursor.
Mouse.OverrideCursor = null;
}
if (source.Name == "rbScopeApplication")
{
// Setting the element only scope flag to false
cursorScopeElementOnly = false;
// Forcing the cursor for all elements.
Mouse.OverrideCursor = DisplayArea.Cursor;
}
}
}

Don't use Mouse.OverrideCursor anywhere otherwise Cursor="Hand" will not work.
不要在任何地方使用 Mouse.OverrideCursor 否则 Cursor="Hand" 将不起作用。
Instead when loading your App call this :
而是在加载您的应用程序时调用：
Mouse.OverrideCursor = null;
Mouse.OverrideCursor = null;
and everywhere call this :
到处都这样称呼：
<Button Cursor="Hand"/>
<Button Cursor="Hand"/>
Using Mouse.OverrideCursor will set the cursor for entire App Space!
使用 Mouse.OverrideCursor 将为整个 App Space 设置光标！

In xaml try
在 xaml 中尝试
<Button x:Name="btn" MouseEnter="btn_OnMouseEnter" MouseLeave="btn_OnMouseLeave" />
in code behind
在后面的代码中
private void btn_OnMouseEnter(object sender, MouseEventArgs e)
{
// example. you can change to a specific type in the Cursors static class
Cursor.Current = Cursors.WaitCursor;
}
private void btn_OnMouseLeave(object sender, MouseEventArgs e)
{
Cursor.Current = Cursors.Default;
}
