Hi All,

I have json array data and converted to xml
Sample json data:

public class jsonInput
   {
       public List<SyncActivity> General { get; set; }


       public List<SyncActivity> RA { get; set; }


       public List<SyncActivity> WA { get; set; }
   }

xml converstion below here

string objActivityDetails = JsonConvert.SerializeObject(Activities);
            XmlDocument xmlObject = JsonConvert.DeserializeXmlNode("{\"root\":" + objDetails.ToString() + "}");

after xml converstion i got the output

<root>
 
<RA>

<MemberId>12333354354</MemberId>

<UserId>4t34534534</UserId>

<CreatedBy>45435345</CreatedBy>

<UpdatedBy>0</UpdatedBy>

<UpdatedDate/>

</RA>
<pre><RA>

<MemberId>12333354354</MemberId>

<UserId>4t34534534</UserId>

<CreatedBy>45435345</CreatedBy>

<UpdatedBy>0</UpdatedBy>

<UpdatedDate/>

</RA>

<WA>

<MemberId>12333354354</MemberId>

<UserId>4t34534534</UserId>

<CreatedBy>45435345</CreatedBy>

<UpdatedBy>0</UpdatedBy>

<UpdatedDate/>

</WA>
<pre><WA>

<MemberId>12333354354</MemberId>

<UserId>4t34534534</UserId>

<CreatedBy>45435345</CreatedBy>

<UpdatedBy>0</UpdatedBy>

<UpdatedDate/>

</WA>

But i need below format :

<roo>
<WA MemberId="12333354354" UserId="4t34534534" CreatedBy="45435345" />
<WA MemberId="12333354354" UserId="4t34534534" CreatedBy="45435345" />

<RA MemberId="12333354354" UserId="4t34534534" CreatedBy="45435345" />
<RA MemberId="12333354354" UserId="4t34534534" CreatedBy="45435345" />
</root>

please let me know you're valuable feedback.

Why (attributes and elements are the same)?

I will pass the XML data to SP. I have heavy data to transfer SP

If you want to stick with this inefficient approach, you'll need the JSON property names to be prefixed with the "@" character:

C#

public class SyncActivity
{
    [JsonProperty("@MemberId")]
    public string MemberId { get; set; }
    
    [JsonProperty("@UserId")]
    public string UserId { get; set; }
    
    [JsonProperty("@CreatedBy")]
    public int CreatedBy { get; set; }
    
    [JsonProperty("@UpdatedBy")]
    public int UpdatedBy { get; set; }
    
    [JsonProperty("@UpdatedDate")]
    public DateTime UpdatedDate { get; set; }
}

Converting between JSON and XML[^]

But converting your object to JSON just to convert it back to XML is horribly inefficient. It would be much simpler to convert the object directly to XML:

C#

XDocument document = new XDocument(
    new XElement("root",
        Activities.General.Select(a => new XElement("General",
            new XAttribute("MemberId", a.MemberId),
            new XAttribute("UserId", a.UserId),
            new XAttribute("CreatedBy", a.CreatedBy),
            new XAttribute("UpdatedBy", a.UpdatedBy),
            new XAttribute("UpdatedDate", a.UpdatedDate)
        )),
        Activities.RA.Select(a => new XElement("RA",
            new XAttribute("MemberId", a.MemberId),
            new XAttribute("UserId", a.UserId),
            new XAttribute("CreatedBy", a.CreatedBy),
            new XAttribute("UpdatedBy", a.UpdatedBy),
            new XAttribute("UpdatedDate", a.UpdatedDate)
        )),
        Activities.WA.Select(a => new XElement("WA",
            new XAttribute("MemberId", a.MemberId),
            new XAttribute("UserId", a.UserId),
            new XAttribute("CreatedBy", a.CreatedBy),
            new XAttribute("UpdatedBy", a.UpdatedBy),
            new XAttribute("UpdatedDate", a.UpdatedDate)
        ))
    )
);

This will also give you complete control over the format of the generated XML document.
