How to convert a specified node to an array when json.net XML is converted to JSON format

Usingusing  Newtonsoft.json;   " Application/json "  = xdocument.load (path); Response.Write (Jsonconvert.serializexnode (Xdoc));

XML fragment:

<specialty namecn="Electrical Measurement"> <step> <signer staffid="800706"namecn=""><! [cdata[]]></signer> </step> <step> <signer staffid="090477"namecn=""><! [cdata[]]></signer> </step> </specialty> <specialty namecn="Energy Saving"> <step> <signer staffid="800608"namecn=""><! [cdata[]]></signer> <signer staffid="800808"namecn=""><! [cdata[]]></signer> </step> <step> <signer staffid="800602"namecn=""><! [cdata[]]></signer> <signer staffid="800803"namecn=""><! [cdata[]]></signer> </step> </specialty>

Output JSON results:

{  "@nameCN":"Electrical Measurement",  "Step": [    {      "signer": {        "@staffID":"800706",        "@nameCN":"",        "#cdata-section":       }    },    {      "signer": {        "@staffID":"090477",        "@nameCN":"",        "#cdata-section":       }    } ]},{  "@nameCN":"Energy Saving",  "Step": [    {      "signer": [        {          "@staffID":"800608",          "@nameCN":"",          "#cdata-section":         },        {          "@staffID":"800808",          "@nameCN":"",          "#cdata-section":         }      ] },    {      "signer": [        {          "@staffID":"800602",          "@nameCN":"",          "#cdata-section":         },        {          "@staffID":"800803",          "@nameCN":"",          "#cdata-section":         }      ] }  ]}

The above results are marked in red is the difference,step under a plurality of signer nodes, the output signer is an array ,

only 1 signer node output signer is not an array , how to output a number when there is only one signer node
