Current JsonReader item is not an object

Question

First I made an application and then I've started doing test for it ( Know it is not good way ), everything works fine with parsing etc, but after i made few test got an error :

Newtonsoft.Json.JsonReaderException : Error reading JObject from JsonReader. Current JsonReader item is not an object: StartArray. Path '', line 1, position 1.

Error occurs there jObject = JObject.Parse(content); and there arrayList = JArray.Parse(content);

internal JObject DoParse(string content)
{
    JObject jObject = new JObject();
    if (content != null)
    {
        if (content.Contains("Unable"))
        {
            MessageBox.Show("Not found.", "Error");
        }
        else
        {
            jObject = JObject.Parse(content);
        }
    }
    return jObject;
}

internal JArray DoParseOnList(string content)
{
    JArray arrayList = new JArray();
    if (content != null)
    {
        if (content.Contains("Unable"))
        {
            MessageBox.Show("Not found.", "Error");
        }
        else
        {

            arrayList = JArray.Parse(content);
        }
    }
    else { }
    return arrayList;
}

Any ideas what is wrong ? Btw. string content is json which i got from the server. Thanks in advance !

Answer 1

I have similar issue.
The returned JSON is Array/List but not Object.
Instead, I use JArray.Parse and it works.

jArray = JArray.Parse(content);

Answer 2

I ran into a very similar problem. The reason my JObject.Parse(json) would not work for me was because my Json had a beginning "[" and an ending "]". In order to make it work, I had to remove those two characters. I would inspect your Json and make sure that it starts with a { and ends with a }.

For me, I removed the first and last characters.

jsonResult = jsonResult.TrimStart(new char[] { '[' }).TrimEnd(new char[] { ']' });
