I am using RestSharp to deserialize a XML file where some of the nodes are like this:
<element value="something" />
The elementes with an attribute called 'value' will not deserialize. Any ideas on how to get RestShap to deserialize this?
The object used to deserialize is like:
public class Object
{
public string Value { get; set; }
}
Please note, the XML is returned from a web service so I do not have the option of changing the attribute name to something different.
Okay, I have found a solution. I think this is somewhat an edge case.
I renamed the variable
public string Value {get;set;}
to
public string value {get;set;}
And now it deserializes perfectly. Guess the Uppercase Value is for the value contained in a XML element only.

Trying convert json to XML with JsonConvert.DeserializeXmlNode(Json.ToString()) and its works but not expected,
First Exapmle:
JSON :
"Emailid": ""
Converted XML :
<Emailid></Emailid>
First example working as expected
Second Example:
JSON :
"ProposalDate": {
"Name": "Proposal Date",
"Value": "06/05/2019"
}
Converted XML :
<ProposalDate>
<Name>Proposal Date</Name>
<Value>06/05/2019</Value>
</ProposalDate>
Expected XML for second example:
<ProposalDate Name="Proposal Date" Value="06/05/2019" />
but for second example want ProposalDate tag with Name and Value property.
What should i do ?
You could deserialize JSON to a class first, apply [XmlAttribute] to the class properties and then serialize the class to XML. See the XmlAttributeAttribute Class documentation.
Your class would look something like this:
public class ProposalDate
{
[XmlAttribute]
public string Name { get; set; }
[XmlAttribute]
public string Value { get; set; }
}
Deserializing JSON to object and serializing object to XML are well documented, and examples easily found.
How I can deserialize json in this case :
(json string I receive from server(in reality the string more and more complex) and can only change it(it's not well as I think) or customize parsing(deserializing) this string, but how do it I don't understand.....)
string json = "[{\"a\":384,\"type\":undefined,\"name\":\"A\"}, {\"a\":385,\"type\":2,\"name\":\"B\"}]";
var t = ser.Deserialize<List<CustClass>>(json);
"type":undefined - raise Exception " Invalid JSON primitive: undefined"
public class CustClass
{
public int a{ get; set; }
public string Name { get; set; }
}
I've try using JavaScriptConverter and JavaScriptTypeResolver but not solve the issue
may be json.net can help me? ....
You should be trying to avoid having things undefined if they are going to be serialized and deserialized. Set default values. Make sure that instead of undefined it passes in an empty string or default value.
If necessary, then I'd suggest checking first, you can do simple for loops through objects, but the easier, more efficient answer, is to not add excess.
How is your JSON being generated? It's complaining because undefined is not allowed as a JSON value. The value null is allowed in JSON, but you need to ensure it won't cause problems when deserialized into a CustClass object.
Just a contrived example but I have some classes that I want to control the names of when serialized.
[XmlRoot("item")]
public class ItemWrapper
{
[XmlArray("parts")]
public List<PartWrapper> Parts { get; set; }
}
[XmlRoot("part")]
public class PartWrapper
{
[XmlAttribute("name")]
public string Name { get; set; }
}
Now when I serialize an ItemWrapper that has some Parts, I was expecting each of the PartWrapper items to be serialized using the root name ("part") but it instead uses the type's name (what it would use by default if the XmlRootAttribute wasn't specified).
<item>
<parts>
<PartWrapper name="foo" />
<PartWrapper name="bar" />
</parts>
</item>
Now I know to fix this to get what I want is to add the XmlArrayItemAttribute to the Parts property to specify the name of each of the items but I feel it's redundant. I just wanted to use the name of the type's root as I specified.
[XmlRoot("item")]
public class Item
{
[XmlArray("parts")]
[XmlArrayItem("part", Type=typeof(PartWrapper))]
public List<PartWrapper> Parts { get; set; }
}
Is there a way that I can tell the serializer that I want to use the root name for the collection items? If so, how?
Why wouldn't it just use the root name? Any good reason why it shouldn't?
It was my understanding that the XmlRootAttribute allowed you to name the element exactly like an XmlElementAttribute does, only it had to be applied to the class. I guess I'm mistaken.
From the documentation, it seems that XmlRootAttribute is used only when that element is the root (which is why it works for "item" in your case):
Controls XML serialization of the attribute target as an XML root element
- MSDN
It seems to me like perhaps you want XmlTypeAttribute for things that are not root.
The XML I am getting is provided by an outside source so I don't have the ability to easily reformat it. I would like to use xml attributes on my entities instead of having to write a linq query that knows how the XML and entity is formatted. Here is an example:
<?xml version="1.0"?>
<TERMS>
<TERM>
<ID>2013-2</ID>
<DESC>Spring 2013</DESC>
</TERM>
<TERM>
<ID>2013-3</ID>
<DESC>Summer 2013 Jun&Jul</DESC>
</TERM>
</TERMS>
I know the the XMLSerializer expects ArrayOfTerm instead of TERMS for example, but that I can tweak my entity to use a different element name with the xml attributes such as this:
public class TermData
{
[XmlArray("TERMS")]
[XmlArrayItem("TERM")]
public List<Term> terms;
}
public class Term
{
[XmlElement("ID")]
public string id;
[XmlElement("DESC")]
public string desc;
}
and I am deserializing the data like so:
TermData data;
XmlSerializer serializer = new XmlSerializer(typeof(TermData));
using (StringReader reader = new StringReader(xml))
{
data = (TermData)serializer.Deserialize(reader);
}
return View(data.terms);
The problem I am facing is that TERMS is the root and the array itself. If the XML were to have a root element that was not the array, I could edit my TermData class like so and it would deserialize correctly (already tested).
[XmlRoot("ROOT")]
public class TermData
{
[XmlArray("TERMS")]
[XmlArrayItem("TERM")]
public List<Term> terms;
}
Note that using TERMS as the XMLRoot does not work. Right now, my code is throwing
InvalidOperationException: There is an error in XML document (2,2).
InnerException: "<TERMS xmlns=" was not expected.
This would lead me to believe that the XML is not formatted correctly, but from my understanding the example I gave is perfectly valid XML.
This would all be trivial if I could edit the source xml, but there could be tons of other responses like this and I need to be able to flex for whatever I might get. What I'm trying to confirm is whether or not the XMLSerializer can support this type of XML structure. I've tested just about everything and can't get it deserialize without editing the XML. It would also be convenient if I didn't have to define a wrapper class (TermData) to hold the list, but this seems to only work if the xml follows the naming conventions for the serializer (ArrayOfTerm, etc).
Maybe you can try :
[XmlRoot("TERMS")]
public class TermData
{
public TermData()
{
terms = new List<Term>();
}
[XmlElement("TERM")]
public List<Term> terms{get;set;}
}
public class Term
{
[XmlElement("ID")]
public string id{get;set;}
[XmlElement("DESC")]
public string desc{get;set;}
}
Hope this will help,
I have the following class that I want to serialize to an XML file
public class HDLCParameters
{
[XmlElement("ClientMACAddress")]
public string ClientMACAddress { get; set; }
}
this is serialized like this:
<HDLCParameters>
<ClientMACAddress>0x10</ClientMACAddress>
</HDLCParameters>
but i need it like this:
<HDLCParameters>
<ClientMACAddress value="0x10" />
</HDLCParameters>
Do i need to create a ClientMACAddress class with a "value" field? isn't there a way to set an element and an attribute with its value?
thanks
Create the ClientMACAddress class, give it a value field, and specify that it's an attribute (XmlAttributeAttribute)
