Getting the name of all DataMembers in a DataContract

Question

I am using WCF service

I have a Data Contract:

[DataContract]
[KnownType(typeof(CustomBranches))]
public class CustomBranches
{
    [DataMember]
    public int Id { get; set; }

    [DataMember]
    public string branch_name { get; set; }

    [DataMember]
    public string address_line_1 { get; set; }

    [DataMember]
    public string city_name { get; set; }
}

Is it possible that i can find the name of all the DataMembers in this class CustomBranches

Like "ID" , "branch name" etc

Thanks

What you need to do:

• You don't need to add [KnownType(typeof(CustomBranches))] in your CustomBranches class. A class always knows about itself.
• You need to filter the properties to only get those with the [DataMember] attribute (nillls' code returned all of them)
• The data member properties can also be non-public (it works if the serialization is running in full trust)
• Data members can also be fields (not only properties), so you need to account for them as well.

This is an example of a code which does all of them.

public class StackOverflow_8152252
{
    public static void Test()
    {
        BindingFlags instancePublicAndNot = BindingFlags.Instance |
            BindingFlags.Public |
            BindingFlags.NonPublic;
        var memberNames = typeof(CustomBranches)
            .GetProperties(instancePublicAndNot)
            .OfType<MemberInfo>()
            .Union(typeof(CustomBranches).GetFields(instancePublicAndNot))
            .Where(x => Attribute.IsDefined(x, typeof(DataMemberAttribute)))
            .Select(x => x.Name);
        Console.WriteLine("All data member names");
        foreach (var memberName in memberNames)
        {
            Console.WriteLine("  {0}", memberName);
        }
    }

    [DataContract]
    public class CustomBranches
    {
        [DataMember]
        public int Id { get; set; }

        [DataMember]
        public string branch_name { get; set; }

        [DataMember]
        public string address_line_1 { get; set; }

        [DataMember]
        public string city_name { get; set; }

        public int NonDataMember { get; set; }

        [DataMember]
        public string FieldDataMember;

        [DataMember]
        internal string NonPublicMember { get; set; }
    }
}
