Documents Error: Can not find DataMember

1

Can not find DataMember, this maybe an error.

public class QueryPerson : QueryBase<Person>
{
    [DataMember("first_name")]
    public string FirstName { get; set; }
}

Seriously? This is exactly what I’m talking about (and just minutes later too!), have you actually searched for DataMember? It shows up as the first Google result. Reference the System.Runtime.Serialization .NET assembly.

Hi
My DataMemeber can not accept parameters, I has resharp so i get this error easy, I think maybe you implement a new data memeber… and then i ask question here…

namespace System.Runtime.Serialization
{
  [AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, AllowMultiple = false, Inherited = false)]

    {

      }
      [__DynamicallyInvokable] set
      {
        this.name = value;
        this.isNameSetExplicit = true;
      }
    }

    internal bool IsNameSetExplicit

[DataMember(Name=“first_name”)]

Hi, I write 7 years C++ and do not know C# very well, forgive me answer too naive questions.

But it’s still a documents error…

So use the Name property:

[DataMember(Name = "first_name")]

Sigh.
