Json.Net How to deserialize null as empty string?

I have string property in my class_ for example

        [DataMember]
        [JsonProperty(PropertyName = "email")]
        [StringLength(40, ErrorMessage = "The Mobile value cannot exceed 40 characters. ")]
        public string Email { get; set; }

By some reason during Convert.Deserialize process I need to have empty string in this property instead on null in case this value is not setup in JSON object. How to do it ?

You could use the DefaultValue attribute.

Decorate it as 

[DataMember]
[JsonProperty(PropertyName = "email", DefaultValueHandling = DefaultValueHandling.Populate)]
[StringLength(40, ErrorMessage = "The Mobile value cannot exceed 40 characters. ")]
[DefaultValue("")]
public string Email { get; set; }
