我在某处读到关闭应用程序时需要处理对象？
我有这个属性，我在拖曳函数中使用它们，我需要调用它们，因为我使用后台工作者。
在大多数情况下，当我关闭我的应用程序时，还可以，但现在我得到了这个异常。
private string CpuTextLabelProperty
{
set
{
if (InvokeRequired)
{
BeginInvoke(new Action(() => CpuTemperature_label.Text = value), null);
}
}
get
{
return CpuTemperature_label.Text;
}
}
private Point CpuLocationLabelProperty
{
set
{
if (InvokeRequired)
{
BeginInvoke(new Action(() => CpuTemperature_label.Location = new Point(210, 200)), null);
}
}
get
{
return CpuTemperature_label.Location;
}
}
private string GpuTextLabelProperty
{
set
{
if (InvokeRequired)
{
BeginInvoke(new Action(() => GpuTemperature_label.Text = value), null);
}
}
get
{
return GpuTemperature_label.Text;
}
}
private Point GpuLocationLabelProperty
{
set
{
if (InvokeRequired)
{
BeginInvoke(new Action(() => GpuTemperature_label.Location= new Point(210,100)), null);
}
}
get
{
return GpuTemperature_label.Location;
}
}
private string Label4TextProperty
{
set
{
if (InvokeRequired)
{
BeginInvoke(new Action(() => label4.Text = value), null);
}
}
}
例外是在属性上：GpuTextLabel属性在获取行中：
返回GpuTemperature_label。发短信;
Win32异常 - 创建窗口句柄时出错
我的 Form1 结束活动：
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (MessageBox.Show("Are you Sure you want to Exit. Click Yes to Confirm and No to continue", "WinForm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
{
e.Cancel = true;
}
else
{
this.BeginInvoke((MethodInvoker)delegate { this.Close(); });
}
}
如果我需要处理一些东西？又如何？
这是使用属性的函数：
private void cpuView()
{
Computer myComputer = new Computer();
myComputer = new Computer(settings) { CPUEnabled = true };
myComputer.Open();
Trace.WriteLine("");
foreach (var hardwareItem in myComputer.Hardware)
{
if (hardwareItem.HardwareType == HardwareType.CPU)
{
hardwareItem.Update();
foreach (IHardware subHardware in hardwareItem.SubHardware)
subHardware.Update();
foreach (var sensor in hardwareItem.Sensors)
{
settings.SetValue("sensor", sensor.Value.ToString());
if (sensor.SensorType == SensorType.Temperature)
{
sensor.Hardware.Update();
settings.GetValue("sensor", sensor.Value.ToString());
int t = CpuTextLabelProperty.Length;
if (t >= 4)
{
CpuLocationLabelProperty = new Point(210, 200); // not working to check everything about the locations \
}
else
{
CpuLocationLabelProperty = new Point(250, 200);
}
CpuTextLabelProperty = sensor.Value.ToString() + "c";//String.Format("{0} Temperature = {1}c", sensor.Name, sensor.Value.HasValue ? sensor.Value.Value.ToString() : "no value");
tempCpuValue = sensor.Value;
break;
}
}
}
}
}
private void gpuView()
{
Computer computer = new Computer();
computer.Open();
computer.GPUEnabled = true;
foreach (var hardwareItem in computer.Hardware)
{
if (videoCardType("ati", "nvidia") == true)
{
HardwareType htype = HardwareType.GpuNvidia;
if (hardwareItem.HardwareType == htype)
{
foreach (var sensor in hardwareItem.Sensors)
{
if (sensor.SensorType == SensorType.Temperature)
{
sensor.Hardware.Update();
if (sensor.Value.ToString().Length > 0)
{
if (GpuTextLabelProperty.Length < 1)
{
if (UpdatingLabel(sensor.Value.ToString(), string.Empty))
{
// Label8 = GpuText;
}
}
else if (UpdatingLabel(sensor.Value.ToString(), GpuTextLabelProperty.Substring(0, GpuTextLabelProperty.Length - 1)))
{
// Label8 = GpuText;
}
GpuTextLabelProperty = sensor.Value.ToString() + "c";
tempGpuValue = sensor.Value;
//label8.Visible = true;
}
int t = GpuTextLabelProperty.Length;
if (t >= 4)
{
GpuLocationLabelProperty = new Point(210, 100);
}
else
{
GpuLocationLabelProperty = new Point(250, 100);
}
// timer2.Interval = 1000;
if (sensor.Value > 90)
{
Logger.Write("The current temperature is ===> " + sensor.Value);
button1.Enabled = true;
}
//this.Select();
}
}
}
}
else
{
HardwareType htype = HardwareType.GpuAti;
if (hardwareItem.HardwareType == htype)
{
foreach (var sensor in hardwareItem.Sensors)
{
if (sensor.SensorType == SensorType.Temperature)
{
sensor.Hardware.Update();
if (sensor.Value.ToString().Length > 0)
{
if (GpuTextLabelProperty.Length < 1)
{
if (UpdatingLabel(sensor.Value.ToString(), string.Empty))
{
// Label8 = GpuText;
}
}
else if (UpdatingLabel(sensor.Value.ToString(), GpuTextLabelProperty.Substring(0, GpuTextLabelProperty.Length - 1)))
{
// Label8 = GpuText;
}
GpuTextLabelProperty = sensor.Value.ToString() + "c";
tempGpuValue = sensor.Value;
//label8.Visible = true;
}
int t = GpuTextLabelProperty.Length;
if (t >= 4)
{
GpuLocationLabelProperty = new Point(210, 100);
}
else
{
GpuLocationLabelProperty = new Point(250, 100);
}
//timer2.Interval = 1000;
if (sensor.Value > 90)
{
Logger.Write("The current temperature is ===> " + sensor.Value);
button1.Enabled = true;
}
this.Select();
}
}
}
}
}
}

关闭
或退出应用程序时，必须停止后台工作线程。异常会抛给你，因为你的代码所依赖的对象正在作系统拆除。
请参阅此线程了解如何执行此操作。
