DataMember could not be found

Question

As I have done my research regarding this problem of mine, I still have no luck in solving my error of Error 1 The type or namespace name 'DataMember' could not be found (are you missing a using directive or an assembly reference?)

I have come across a solution stating that I should reference System.Runtime.Serialization but still I am having no luck even when add reference to it.

Here is my code:

using System;
using System.Linq;
using System.Collections.Generic;
using System.Text;
using System.Runtime.Serialization;
using System.Xml.Serialization;

namespace WebServApp
{
    [Serializable]
    public class Employee
    {
        [DataMember]
        public int EmpNo { get; set; }
        [DataMember]
        public string EmpName { get; set; }
        [DataMember]
        public int DeptNo { get; set; }
        [DataMember]
        public int Salary { get; set; }
    }
}

and this is the tutorial that I am actually trying to follow: http://www.dotnetcurry.com/ShowArticle.aspx?ID=472

Can anyone help me with this error?

Solution 1

I have solved the problem. I just removed the System.Runtime.Serialization in the references in the project explorer and addded it by browsing then it worked. Weird.

Solution 2

Remove System.Runtime.Serialization from code, then add from menu > Project > Add reference ..> . Then again add into code. it works.

Yes, you wrote [Serializable] instead of DataContract . Org:[DataContract(Name = "Employee", Namespace = "")] public class Employee { [DataMember] public int EmpNo { get; set; } [DataMember] public string EmpName { get; set; } [DataMember] public int DeptNo { get; set; } [DataMember] public int Salary { get; set; } }. Sometimes copy and paste is your friend.

Nope. The [Serializable] wasnt the problem. I just did what I did on my answer above. When it worked, I actually removed the [Serializble] in the code but it still worked.

Once you're in the Reference Manager, you'll find System.Runtime.Serialization under the Assemblies > Framework tab.
