string FilePath = ConfigurationReader.FileLocation;   //Getting path value from web.config            
    XmlSerializer serializer = new XmlSerializer(typeof(Devices)); //typeof(object)
            MemoryStream memStream = new MemoryStream();
            serializer.Serialize(memStream, lstDevices);//lstdevices : I take result as a list.
            FileStream file = new FileStream(folderName + "\\Data.xml", FileMode.Create, FileAccess.ReadWrite); //foldername:Specify the path to store the xml file
            memStream.WriteTo(file);
            file.Close();

您可以创建结果并将其作为xml文件存储在所需的位置。

要序列化一个对象，请执行:

 using (StreamWriter myWriter = new StreamWriter(path, false))
 {
     XmlSerializer mySerializer = new XmlSerializer(typeof(your_object_type));
     mySerializer.Serialize(myWriter, objectToSerialize);
 }

还要记住，要使XmlSerializer工作，需要一个无参数构造函数。

我修改了我的返回一个字符串，而不是像下面这样使用一个ref变量。

public static string Serialize<T>(this T value)
{
    if (value == null)
    {
        return string.Empty;
    }
    try
    {
        var xmlserializer = new XmlSerializer(typeof(T));
        var stringWriter = new StringWriter();
        using (var writer = XmlWriter.Create(stringWriter))
        {
            xmlserializer.Serialize(writer, value);
            return stringWriter.ToString();
        }
    }
    catch (Exception ex)
    {
        throw new Exception("An error occurred", ex);
    }
}

它的用法是这样的:

var xmlString = obj.Serialize();

必须使用XmlSerializer进行XML序列化。下面是一个示例代码片段。

 XmlSerializer xsSubmit = new XmlSerializer(typeof(MyObject));
 var subReq = new MyObject();
 var xml = "";

 using(var sww = new StringWriter())
 {
     using(XmlWriter writer = XmlWriter.Create(sww))
     {
         xsSubmit.Serialize(writer, subReq);
         xml = sww.ToString(); // Your XML
     }
 }

根据泛型类的@kiquenet请求:

public class MySerializer<T> where T : class
{
    public static string Serialize(T obj)
    {
        XmlSerializer xsSubmit = new XmlSerializer(typeof(T));
        using (var sww = new StringWriter())
        {
            using (XmlTextWriter writer = new XmlTextWriter(sww) { Formatting = Formatting.Indented })
            {
                xsSubmit.Serialize(writer, obj);
                return sww.ToString();
            }
        }
    }
}

用法:

string xmlMessage = MySerializer<MyClass>.Serialize(myObj);

这里有一个关于如何做到这一点的很好的教程

基本上应该使用System.Xml.Serialization.XmlSerializer类来做到这一点。

我将从本·格里普卡的回答开始:

public void Save(string FileName)
{
    using (var writer = new System.IO.StreamWriter(FileName))
    {
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();
    }
}

I used this code earlier. But reality showed that this solution is a bit problematic. Usually most of programmers just serialize setting on save and deserialize settings on load. This is an optimistic scenario. Once the serialization failed, because of some reason, the file is partly written, XML file is not complete and it is invalid. In consequence XML deserialization does not work and your application may crash on start. If the file is not huge, I suggest first serialize object to MemoryStream then write the stream to the File. This case is especially important if there is some complicated custom serialization. You can never test all cases.

public void Save(string fileName)
{
    //first serialize the object to memory stream,
    //in case of exception, the original file is not corrupted
    using (MemoryStream ms = new MemoryStream())
    {
        var writer = new System.IO.StreamWriter(ms);    
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();

        //if the serialization succeed, rewrite the file.
        File.WriteAllBytes(fileName, ms.ToArray());
    }
}

现实场景中的反序列化应该与损坏的序列化文件算在一起，它有时会发生。负载函数由Ben Gripka提供。

public static [ObjectType] Load(string fileName)
{
    using (var stream = System.IO.File.OpenRead(fileName))
    {
        var serializer = new XmlSerializer(typeof([ObjectType]));
        return serializer.Deserialize(stream) as [ObjectType];        
    }    
}

它可能会被一些复苏场景所包裹。它适用于设置文件或其他文件，可以删除的情况下出现问题。

public static [ObjectType] LoadWithRecovery(string fileName)
{
    try
    {
        return Load(fileName);
    }
    catch(Excetion)
    {
        File.Delete(fileName); //delete corrupted settings file
        return GetFactorySettings();
    }
}
