将对象转换为 XML 字符串 [英] Convert an object to an XML string

问题描述

我有一个名为 WebserviceType 的类，我是从 XSD 文件的工具 xsd.exe 中得到的.

现在我想将 WebServiceType 对象的实例反序列化为字符串.我该怎么做?

MethodCheckType 对象有一个 WebServiceType 数组作为参数.

我的第一次尝试就像我序列化它一样:使用 XmlSerializer 和一个 StringWriter(在序列化时我使用了 StringReader).

这是我序列化WebServiceType对象的方法:

XmlSerializer serializer = new XmlSerializer(typeof(MethodCheckType));MethodCheckType 输出 = null;StringReader 阅读器 = null;//捕获全局异常，记录并抛出尝试{reader = new StringReader(path);输出 = (MethodCheckType)serializer.Deserialize(reader);}捕获(异常){扔;}最后{读者.处置();}返回输出.WebService;

<小时>

也许我可以用不同的话来说:我有这个 MethodCheckType 对象的一个​​实例，另一方面，我有我序列化这个对象的 XML 文档.现在我想将此实例转换为字符串形式的 XML 文档.在此之后，我必须证明两个字符串(XML 文档)是否相同.我必须这样做，因为我对第一种方法进行了单元测试，在该方法中我将 XML 文档读入 StringReader 并将其序列化为 MethodCheckType 对象.

解决方案

这里是两种方式的转换方法.this = 你的类的实例

公共字符串 ToXML(){using(var stringwriter = new System.IO.StringWriter()){var serializer = new XmlSerializer(this.GetType());serializer.Serialize(stringwriter, this);返回 stringwriter.ToString();}}公共静态 YourClass LoadFromXMLString(string xmlText){使用(var stringReader = new System.IO.StringReader(xmlText)){var serializer = new XmlSerializer(typeof(YourClass));返回 serializer.Deserialize(stringReader) 作为 YourClass ；}}

I have got a class named WebserviceType I got from the tool xsd.exe from an XSD file.

Now I want to deserialize an instance of an WebServiceType object to a string. How can I do this?

The MethodCheckType object has as params a WebServiceType array.

My first try was like I serialized it: with a XmlSerializer and a StringWriter (while serializing I used a StringReader).

This is the method in which I serialize the WebServiceType object:

XmlSerializer serializer = new XmlSerializer(typeof(MethodCheckType));
        MethodCheckType output = null;
        StringReader reader = null;

        // catch global exception, logg it and throw it
        try
        {
            reader = new StringReader(path);
            output = (MethodCheckType)serializer.Deserialize(reader);
        }
        catch (Exception)
        {
            throw;
        }
        finally
        {
            reader.Dispose();
        }

        return output.WebService;

Edit:

Maybe I could say it in different words: I have got an instance of this MethodCheckType object an on the other hand I have got the XML document from which I serialized this object. Now I want to convert this instance into a XML document in form of a string. After this I have to proof if both strings (of XML documents) are the same. This I have to do, because I make unit tests of the first method in which I read an XML document into a StringReader and serialize it into a MethodCheckType object.

解决方案

Here are conversion method for both ways. this = instance of your class

public string ToXML()
    {
        using(var stringwriter = new System.IO.StringWriter())
        { 
            var serializer = new XmlSerializer(this.GetType());
            serializer.Serialize(stringwriter, this);
            return stringwriter.ToString();
        }
    }

 public static YourClass LoadFromXMLString(string xmlText)
    {
        using(var stringReader = new System.IO.StringReader(xmlText))
        {
            var serializer = new XmlSerializer(typeof(YourClass ));
            return serializer.Deserialize(stringReader) as YourClass ;
        }
    }
