WPF鼠标移动触发事件怎么改写成鼠标悬停触发事件

Question

private void diagram_MouseMove(object sender, MouseEventArgs e)

{
if (selectedPoint != null && movepoint != null && Gobal.MainWin.TraceSettingsViewModel.TracesSettings.MovePoint) //线迹修改
{
ChartControl chart = (ChartControl)sender;
//XYDiagram2D diagram = (XYDiagram2D)chart.Diagram;
DiagramCoordinates coord = diagram.PointToDiagram(e.GetPosition(chartControl1));
selectedPoint.Value = coord.NumericalValue;
Gobal.MainWin.ChartViewModel.Trace1[(int)movepoint].Y = coord.NumericalValue;
}
if (!Gobal.MainWin.TraceSettingsViewModel.TracesSettings.MarkEnable) //否标记返回
return;
if (Trace1.Points.Count <= 0) //无数据返回
return; if (!diagramCoordinates.IsEmpty)
{
double fre = Convert.ToDouble(diagramCoordinates.NumericalArgument);
int count = GetSeriesValue(Trace1, fre);
int min, max;
if (count - Gobal.MainWin.TraceSettingsViewModel.TracesSettings.MarkSpan <= 0)
{
min = 0;
}
else
{
min = count - Gobal.MainWin.TraceSettingsViewModel.TracesSettings.MarkSpan;
}
if (count + Gobal.MainWin.TraceSettingsViewModel.TracesSettings.MarkSpan >= Trace1.Points.Count)
{
max = Trace1.Points.Count - 1;
}
else
{
max = count + Gobal.MainWin.TraceSettingsViewModel.TracesSettings.MarkSpan;
}

            WPF里目前我有一个鼠标移动事件，由于数据量大，触发效果不好，有点卡顿，现在想把这个鼠标移动触发 变成 鼠标悬停触发 求解各位大神，如知道加我微信xiaoyi895860863必带红包答谢

Answer 1

定义一个bool变量
在mouse_enter里设置为true
在mouse_move里判断，如果为true，那么调用你的代码，并且设置为false
在mouse_leave里设置为false
