【问题描述】：

所以我正在使用 WPF 制作一个 GUI。所有的 GUI 交互（选择复选框、填写文本框等）都将作为参数发送到 Python 脚本，并指示 Python 脚本最终将处理什么。在大多数情况下，大多数数据都传递了固定数量的元素，但是，我传递的最后两条数据的大小取决于用户输入的内容（这些变量是 frequencyDynamicList 和 frequencyIndexList） .将这些数组作为参数发送的最佳方式是什么？

private static void run(string path, int[] temperatureList, int[] dataList, float[] toggleData, int toggleEnable, int[] bandEnable, List<string> frequencyDynamicList, List<int> frequencyIndexList)
{
    Process p = new Process();
    ProcessStartInfo startInfo = new ProcessStartInfo();
    //startInfo.WindowStyle = ProcessWindowStyle.Hidden;
    startInfo.FileName = "cmd.exe";
    startInfo.Arguments = "/c \"python ProcessDataGUI.py\"" + " "
                              + path + " "
                              + temperatureList[0] + " " + temperatureList[1] + " " + temperatureList[2] + " " + temperatureList[3] + " " + temperatureList[4] + " "
                              + dataList[0] + " " + dataList[1] + " " + dataList[2] + " " + dataList[3] + " " + dataList[4] + " " + dataList[5] + " " + dataList[6] + " "
                              + toggleData[0] + " " + toggleData[1] + " " + toggleData[2] + " " + toggleData[3] + " " + toggleData[4] + " " + toggleData[5] + " " + toggleData[6] + " "
                              + toggleEnable + " "
                              + bandEnable[0] + " " + bandEnable[1] + " " + bandEnable[2] + " "
                              + frequencyDynamicList.ToArray() + " " + frequencyIndexList.ToArray();
    p.StartInfo = startInfo;
    p.Start();
}

嵌入 Python 将消除启动新进程的开销。 docs.python.org/3/extending/embedding.html

【解决方案1】：

首先，我建议您使用类而不是自变量。

private class MyData {
    int[] TemperatureList { get; set; }
    int[] DataList { get; set; }
    float[] ToggleData { get; set; }
    int ToggleEnable { get; set; }
    int[] BandEnable { get; set; }
    List<string> FrequencyDynamicList { get; set; }
    List<int> FrequencyIndexList { get; set; }
}

那么就可以使用下面的代码了：

private static void run(string path, MyData myData)
        {
            Process p = new Process();
            ProcessStartInfo startInfo = new ProcessStartInfo();
            //startInfo.WindowStyle = ProcessWindowStyle.Hidden;
            startInfo.FileName = "cmd.exe";
            startInfo.Arguments = "/c \"python ProcessDataGUI.py\"" + " "
                                  + path + " "
                                  + string.Join(" ", myData.TemperatureList.Cast<int>().ToList()) + " "
                                  + string.Join(" ", myData.DataList.Cast<int>().ToList()) + " "
                                  + string.Join(" ", myData.ToggleData.Cast<float>().ToList()) + " "
                                  + toggleEnable + " "
                                  + string.Join(" ", myData.BandEnable.Cast<int>().ToList()) + " "
                                  + string.Join(" ",FrequencyDynamicList); + " " 
                                  + string.Join(" ",FrequencyIndexList);
            p.StartInfo = startInfo;
            p.Start();
        }
