将JSON反序列化为C＃对象：如何处理缺失的属性

Question

I have a problem, my JSON object does not contain all the properties which are available in C# object (DataMember).

Is there any way I can ignore missing properties while deserializing JSON

/// <summary>
        /// Deserializes a stream that contains a json text into an object.
        /// </summary>
        /// <typeparam name="T">The type of the object to be deserialized into.</typeparam>
        /// <param name="stream">The stream that contains the json text representation of the object.</param>
        /// <returns>A deserialized object.</returns>
        public static T DeserializeJson<T>(Stream stream) where T : class 
        {
            DataContractJsonSerializerSettings settings = new DataContractJsonSerializerSettings();
            settings.UseSimpleDictionaryFormat = true;

            DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(T), settings);
            return jsonSerializer.ReadObject(stream) as T;
        }

You can specify IsRequired property for DataMemberAttribute . If you set it to false , deserialisation won't throw exception if this member is missing in your json.

    [DataMember( IsRequired = false )]
    public bool ManualSessionClose { get; set; }
