    Transfering structure from WebService

    It's well known that IDictionary collections present run-time exceptions if
    you attempt to serialize them across Web service boundaries.

    I need transfer data from this struct:

    private struct OnlineRecordDat a
    {
    public string WITS;
    public float Value;
    ....
    }

    I use this technic to transfer data:

    [WebMethod]
    public List<stringOnli neRecord()
    {
    // data sample
    OnlineRecordDat a[] a = new OnlineRecordDat a[100];
    // populate a[] from database...

    List<stringr = new List<string>();

    for (int i = 0; i <= a.GetUpperBound (0); i++)
    {
    r.Add(a[i].WITS + "=" + a[i].Value.ToString ("E"));
    }
    return r;
    }

    My question is: Is there is some way to write this more efficient code? ...
    I need the best speed

    Thanks in advanced,

      The best solution from a object oriented and portability aspect would be
      to return an array of your class.

      In your code return a.

      Just make OnlineRecordDat a serializable (and possible use private fields
      and public properties).

          Do you mean me that with BinaryFormatter is more efficient?

                  Binary is absolutely faster than SOAP XML.

                  But it would not be a real web service anymore.
