I have two format of JSON which I want to Deserialize to one class. I know we can't apply two [JsonProperty] attribute to one property.

Can you please suggest me a way to achieve this?

string json1 = @"
    {
        'field1': '123456789012345',
        'specifications': {
            'name1': 'HFE'
        }
    }";

string json2 = @"
    {
        'field1': '123456789012345',
        'specifications': {
            'name2': 'HFE'
        }
    }";

public class Specifications
{
    [JsonProperty("name1")]
    public string CodeModel { get; set; }
}

public class ClassToDeserialize
{
    [JsonProperty("field1")]
    public string Vin { get; set; }

    [JsonProperty("specification")]
    public Specifications Specifications { get; set; }        
}

I want name1 and name2 both to be deserialize to name1 property of specification class.

A simple solution which does not require a converter: just add a second, private property to your class, mark it with [JsonProperty("name2")], and have it set the first property:

public class Specifications
{
    [JsonProperty("name1")]
    public string CodeModel { get; set; }

    [JsonProperty("name2")]
    private string CodeModel2 { set { CodeModel = value; } }
}
