创建您的settings.xml。例如，它具有以下结构：

<?xml version="1.0"?>
<COMSettings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Port>COM16</Port>
</COMSettings>

字符串
创建一个类来将你的xml文件转换到它里面：

public class COMSettings
{
    public string Port { get; set; };

    // some other data if needed
 
    public COMSettings() { }
    public COMSettings(string port)
    {
        Port = port;
    }
}

型
用法很简单--读取并格式化xml，然后只使用端口值。

using System.Xml.Serialization;

...

// somewhere in your app
var xmlSerializer = new XmlSerializer(typeof(COMSettings));

using (var fs = new FileStream("settings.xml", FileMode.OpenOrCreate));

var settings = xmlSerializer.Deserialize(fs) as COMSettings;

// usage
var command = $"command filename.py {settings.Port}";
