Follow 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 Property1 property and this property is always null.

How can I resolve this?

c# json array

As stated in the comment Roberto Json is Array , however, no should 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 make Deserialize :

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