]

Follows the classes:

public class Rootobject
    {
        public Class1[] Property1 { get; set; }
    }

    public class Class1
    {
        public string id { get; set; }
        public string agencyNumber { get; set; }
        public string accountNumber { get; set; }
        public Holder holder { get; set; }
        public string status { get; set; }
        public DateTime createdAt { get; set; }
        public string accountCheckNumber { get; set; }
        public _Links _links { get; set; }
        public string bankName { get; set; }
        public string type { get; set; }
        public string agencyCheckNumber { get; set; }
        public string bankNumber { get; set; }
    }

    public class Holder
    {
        public bool thirdParty { get; set; }
        public Taxdocument taxDocument { get; set; }
        public string fullname { get; set; }
    }

    public class Taxdocument
    {
        public string number { get; set; }
        public string type { get; set; }
    }

    public class _Links
    {
        public Self self { get; set; }
    }

    public class Self
    {
        public string href { get; set; }
    }

Follow the logic to deserialize:

var result = JsonConvert.DeserializeObject<Rootobject[]>(json);

Each array has its own property Property1 and this property is always null.

How can I fix this ?

    The informed json appears to be an object array Classe1. Try the following: var result = JsonConvert.DeserializeObject<Classe1[]>(json);

As stated in the commentary of Roberto the Json is a Array, however, should not have this public Class1[] Property1 { get; set; }, leave your class like this:

public class TaxDocument
{
    public string number { get; set; }
    public string type { get; set; }
}

public class Holder
{
    public bool thirdParty { get; set; }
    public TaxDocument taxDocument { get; set; }
    public string fullname { get; set; }
}

public class Self
{
    public string href { get; set; }
}

public class Links
{
    public Self self { get; set; }
}

public class RootObject
{
    public string id { get; set; }
    public string agencyNumber { get; set; }
    public string accountNumber { get; set; }
    public Holder holder { get; set; }
    public string status { get; set; }
    public DateTime createdAt { get; set; }
    public string accountCheckNumber { get; set; }
    public Links _links { get; set; }
    public string bankName { get; set; }
    public string type { get; set; }
    public string agencyCheckNumber { get; set; }
    public string bankNumber { get; set; }
}

And to do the Deserialize:

var result = JsonConvert.DeserializeObject<List<Rootobject>>(json);

You can use the website http://json2csharp.com/ to generate the respective classes of a Json

Reading tip: What is the difference between keys "{ }" and brackets "[ ]"?

  • I used the "Paste special as json" menu option, that’s where it failed :/
