this.m_objIGXFeatureControl.GetEnumFeature("TriggerMode").SetValue("Off"); this.m_objIGXFeatureControl.GetEnumFeature("TriggerSelector").SetValue("FrameStart"); this.m_objIGXFeatureControl.GetEnumFeature("TriggerSource").SetValue("Line0"); this.m_objIGXFeatureControl.GetEnumFeature("AcquisitionFrameRateMode").SetValue("Off"); this.m_objIGXFeatureControl.GetEnumFeature("ExposureAuto").SetValue("Off"); this.m_objIGXFeatureControl.GetFloatFeature("ExposureTime").SetValue(this.Param.ExposureTime); this.m_objIGXFeatureControl.GetEnumFeature("GainSelector").SetValue("AnalogAll"); this.m_objIGXFeatureControl.GetFloatFeature("Gain").SetValue(this.Param.Gain); this.m_objIGXFeatureControl.GetEnumFeature("TriggerActivation").SetValue(this.Param.TriggerActivation.ToString());

这段代码是在使用机器视觉相机控制软件开发时的一些设置，具体的作用如下：

1. `this.m_objIGXFeatureControl.GetEnumFeature("TriggerMode").SetValue("Off");`：关闭相机的触发模式。

2. `this.m_objIGXFeatureControl.GetEnumFeature("TriggerSelector").SetValue("FrameStart");`：设置触发器选择器为帧起始。

3. `this.m_objIGXFeatureControl.GetEnumFeature("TriggerSource").SetValue("Line0");`：设置触发源为第0行。

4. `this.m_objIGXFeatureControl.GetEnumFeature("AcquisitionFrameRateMode").SetValue("Off");`：关闭相机的帧率控制模式。

5. `this.m_objIGXFeatureControl.GetEnumFeature("ExposureAuto").SetValue("Off");`：关闭相机的自动曝光模式。

6. `this.m_objIGXFeatureControl.GetFloatFeature("ExposureTime").SetValue(this.Param.ExposureTime);`：设置相机的曝光时间。

7. `this.m_objIGXFeatureControl.GetEnumFeature("GainSelector").SetValue("AnalogAll");`：设置增益选择器为模拟增益。

8. `this.m_objIGXFeatureControl.GetFloatFeature("Gain").SetValue(this.Param.Gain);`：设置相机的增益。

9. `this.m_objIGXFeatureControl.GetEnumFeature("TriggerActivation").SetValue(this.Param.TriggerActivation.ToString());`：设置触发激活模式。

这些设置可以根据实际需求进行调整和修改。

string json = File.ReadAllText("tsconfig1.json"); dynamic jsonObj = JsonConvert.DeserializeObject(json); dShutterValue = jsonObj["exposureTime"]; m_txt_Shutter.Text = dShutterValue.ToString("F2"); m_listCCamerInfo[m_nOperateID].m_objIGXFeatureControl.GetFloatFeature("ExposureTime").SetValue(dShutterValue); m_txt_Shutter.Clear(); try { if (!m_listCCamerInfo[m_nOperateID].m_bIsOpen) { return; } strValue = m_listCCamerInfo[m_nOperateID].m_objIGXFeatureControl.GetFloatFeature("ExposureTime").GetValue().ToString(); //浮点转字符串 dShutterValue = Convert.ToDouble(m_txt_Shutter.Text); 怎么改错System.FormatException:“输入字符串的格式不正确。”

System.FormatException: The format of the input string is incorrect.

The error occurs because the `Convert.ToDouble()` method is unable to parse the value in `m_txt_Shutter.Text` as a valid double. To fix this error, you can add error handling to handle cases where the input string cannot be converted to a double.

Here is an updated version of the code with error handling:

try
{
    if (!m_listCCamerInfo[m_nOperateID].m_bIsOpen)
    {
        return;
    }

    if (double.TryParse(m_txt_Shutter.Text, out dShutterValue))
    {
        m_listCCamerInfo[m_nOperateID].m_objIGXFeatureControl.GetFloatFeature("ExposureTime").SetValue(dShutterValue);
        strValue = dShutterValue.ToString("F2");
    }
    else
    {
        // Handle invalid input here
        // For example, display an error message or set a default value
    }
}
catch (Exception ex)
{
    // Handle any other exceptions here
    // Log the exception or display an error message
}

In this code, `double.TryParse()` is used to attempt to parse the input string as a double. If the parsing is successful, the `dShutterValue` will be assigned the parsed value, and you can proceed with setting the value and converting it to a formatted string. If the parsing fails, you can handle the invalid input case as needed.
