反序列化XML文件 [英] Deserialize XML File
问题描述
我花了几个小时试图反序列化和XML文件，但仍然失败。我把它归结为以下工作：
I have spent a few hours trying to deserialize and XML file but still fail. I boiled it down to the following which WORKS:
XML文件：
<实体xmlns：xsi ='http：//www.w3.org/ 2001 / XMLSchema-instance'xmlns：xsd ='http：//www.w3.org/2001/XMLSchema'>
<实体>
<名称> a< /名称>
< / Entity>
<实体>
<名称> b< /名称>
< / Entity>
< / Entities>
XML File:
<Entities xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
<Entity>
<Name>a</Name>
</Entity>
<Entity>
<Name>b</Name>
</Entity>
</Entities>
在此我运行生成类的xsd.exe。这个类有点长，所以我不会在这里列出它，但我列出了一个在底部不起作用的那个。无论如何，这是我如何反序列化XML文件：
XmlSerializer ser = new XmlSerializer（typeof（Entities））;
FileStream fs = new FileStream（" Input.xml" ;，FileMode.Open）;
$
实体ents =（实体）ser.Deserialize（fs）;
On this I run xsd.exe which generates a class. That class is kind of long so I won't list it here but I list the one that doesn't work at the bottom. Anyways, here is how I deserialize the XML file:
XmlSerializer ser = new XmlSerializer(typeof(Entities));
FileStream fs = new FileStream("Input.xml", FileMode.Open);
Entities ents = (Entities)ser.Deserialize(fs);
这很好用。但是，我的XML文件有一些扩展名如下：
< Entities xmlns：xsi ='http：//www.w3.org/2001/XMLSchema-instance'xmlns：xsd ='http： //www.w3.org/2001/XMLSchema'>
<实体>
<名称> a< /名称>
<属性>
< Property>
<名称> aa1Name< /名称>
< / Property>
< Property>
<名称> aa2Name< /名称>
< / Property>
< / Properties>
< / Entity>
<实体>
<名称> b< /名称>
< / Entity>
< /实体>
This works fine. However, my XML file has some extension like this:
<Entities xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
<Entity>
<Name>a</Name>
<Properties>
<Property>
<Name>aa1Name</Name>
</Property>
<Property>
<Name>aa2Name</Name>
</Property>
</Properties>
</Entity>
<Entity>
<Name>b</Name>
</Entity>
</Entities>
现在，如果我运行与上面相同的代码，我会收到错误：
$
无法生成临时类（result = 1）。
错误CS0030：无法将类型'[Namespace] .EntitiesEntityPropertiesProperty []'转换为'[Namespace]。 EntitiesEntityPropertiesProperty'
$
错误CS0029：无法将类型'[Namespace] .EntitiesEntityPropertiesProperty'隐式转换为'[Namespace] .EntitiesEntityPropertiesProperty []'
Now if I run the same code as above I get the error:
Unable to generate a temporary class (result=1).
error CS0030: Cannot convert type '[Namespace].EntitiesEntityPropertiesProperty[]' to '[Namespace].EntitiesEntityPropertiesProperty'
error CS0029: Cannot implicitly convert type '[Namespace].EntitiesEntityPropertiesProperty' to '[Namespace].EntitiesEntityPropertiesProperty[]'
为什么这不起作用？我只是在XML文件中添加另一个级别并使用xsd.exe重新生成类
Why does this not work? I am just adding another level to the XML file and regenerate the class with xsd.exe
这是xsd.exe生成的类具有"属性"部分的xml文件：

Here is the class that xsd.exe generated for the xml file that has the Properties section:

推荐答案
尝试不同的方法：将XML文本复制到剪贴板，然后转到Visual Studio，转到某些代码文件，然后从菜单执行：编辑，选择性粘贴，粘贴XML
作为类。
似乎应该用'[]'替换'[] []'。
