C# 如何保存不断变化的变量的当前值？
我正在WPF应用程序中的类型双变量中存储传感器的度数读数，C# 如何保存不断变化的变量的当前值？,c#,wpf,double,myo,C#,Wpf,Double,Myo,我正在WPF应用程序中的类型双变量中存储传感器的度数读数，degreeOutput来自Thlamic实验室的Myo传感器。当用户移动手臂时，变量中存储的值会不断变化，但我希望在人做出拳头姿势时，存储运动中某一点的度数读数，而不是不断变化的值 在我当前的实现中，我触发degreeOutput的值以显示在PainfulArcStartBx中，以表示我要测量的弧的起始值，但这不符合计划 相反，当握紧拳头时，度值输出到文本框，但不断变化 我只想在握拳时输出初始读数，之后不输出任何读数 应该在放开第一个姿
degreeOutput拳头degreeOutputPainfulArcStartBxprivate void Myo_OrientationDataAcquired(object sender, OrientationDataEventArgs e)
{
App.Current.Dispatcher.Invoke((Action)(() =>
{
//need to record degree reading when pose made that
//signifies begining of painful arc.
//then specify a second pose that signals the end of
//painful arc and store arc reading, eg 92dg - 108dg
//myo indicator must be facing down or degrees will be inverted.
degreeOutput = ((e.Pitch + PITCH_MIN) * CALLIBRATION_FACTOR);
degreeOfAbductionTbx.Text = "Degree: " + degreeOutput;
if(e.Myo.Pose == Pose.Fist)
{
//get the start reading of the painful arc
painfulArcStartTbx.Text = "start: " + degreeOutput;
}
//then get the finish reading of the painful arc
//after the fist pose has been let go, indicating
//end of pain in movement
else
{
painfulArcEndTbx.Text = "end: " + degreeOutput;

}));
}
我可能完全错了，因为我不知道那个传感器是什么，但似乎你错过了一些非常基本的东西：
private string startingDegree;
private string endDegree;
private void Myo_OrientationDataAcquired(object sender, OrientationDataEventArgs e)
{
App.Current.Dispatcher.Invoke((Action)(() =>
{
//need to record degree reading when pose made that
//signifies begining of painful arc.
//then specify a second pose that signals the end of
//painful arc and store arc reading, eg 92dg - 108dg
//myo indicator must be facing down or degrees will be inverted.
degreeOutput = ((e.Pitch + PITCH_MIN) * CALLIBRATION_FACTOR);
degreeOfAbductionTbx.Text = "Degree: " + degreeOutput;
if(e.Myo.Pose == Pose.Fist)
{
endDegree = string.Empty;
if(string.IsNullOrEmpty(startingDegree))
{
startingDegree = "start: " + degreeOutput;
}
//get the start reading of the painful arc
painfulArcStartTbx.Text = startingDegree;
}
//then get the finish reading of the painful arc
//after the fist pose has been let go, indicating
//end of pain in movement
else
{
startingDegree = string.Empty;
if(string.IsNullOrEmpty(endDegree))
{
endDegree = "end: " + degreeOutput;
}
painfulArcEndTbx.Text = endDegree;
}
}));
}
我会用双份的？但这就是我刚才键入的内容。@TonyHopkinson给出了这一行：
