Entity must be parameterless?

Entity must be parameterless?

• Kinetic Media

  Thanks Vakram. After I added the parameterless constructor, I get the following error: What is wrong Thanks again.

  System.ApplicationException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> There was an error generating the XML document. ---> The type Entity.eWarehouse was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically. at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at BEInternetAccess.OthersServ.GetWarehouses(String strConn, String strLanguage, Boolean booHasAll) at BLL.Warehouse.GetWarehouses(String strConn, String strWS_URL, String strTypeOfConnection, String strLanguage, Boolean booHasAll) at BLL.Warehouse.GetWarehouses(String strConn, String strWS_URL, String strTypeOfConnection, String strLanguage, Boolean booHasAll) at Techwave.BizEasy.PSL.Core.FormMain.FormInvoiceView.FormInvoiceView_Load(Object sender, EventArgs e)

  The Entity is simple:

  [Serializable()]
  public class eWarehouse
  {
  private string _strWarehouseName ;
  private int _intWarehouseNo;
  private decimal _decQuantity=0;

  public eWarehouse()
  {
  }

  public eWarehouse(int intWarehouseNo, string strWarehouseName, decimal decQuantity)
  {
  this._strWarehouseName = strWarehouseName;
  this._intWarehouseNo = intWarehouseNo;
  }

  public string WarehouseName
  {
  get { return this._strWarehouseName; }
  set { this._strWarehouseName = value; }

  }

  public int WarehouseNo
  {
  
  get { return this._intWarehouseNo; }
  set { this._intWarehouseNo = value; }
  }

  public decimal Quantity
  {

  get { return this._decQuantity; }
  set { this._decQuantity = value; }
  }
  }

  But why

  I hate adding something to my code without understanding it.

  Kennon,

  Could you show some of the client-side code, as well as the signature of the server-side method (webmethod) that you're trying to call

  Here are the related calls:

  Web Service

      [WebMethod]
      public ArrayList GetWarehouses(string strConn, string strLanguage, bool booHasAll)
      {
              return DAL.dWarehouse.GetWarehouses(strConn, strLanguage, booHasAll);
          throw new ApplicationException("Invalid login.");
      }

  Data Access Layer

    public static ArrayList GetWarehouses(string strConn, string strLanguage, bool booHasAll)
    {
     ArrayList alWarehouse = new ArrayList(5);

     DataSet ds = dDefault.GetDataSetDefaultLikes("WarehouseName", strConn);
    

      alWarehouse.Add(new eWarehouse(0, ds.Tables[0].Rows[0]["PropertyValue"] == null "Wh 0" : ds.Tables[0].Rows[0]["PropertyValue"].ToString(), 0));    alWarehouse.Add(new eWarehouse(1, ds.Tables[0].Rows[1]["PropertyValue"] == null "Wh 1" : ds.Tables[0].Rows[1]["PropertyValue"].ToString(), 0));
                  alWarehouse.Add(new eWarehouse(2, ds.Tables[0].Rows[2]["PropertyValue"] == null "Wh 2" : ds.Tables[0].Rows[2]["PropertyValue"].ToString(), 0));
                  alWarehouse.Add(new eWarehouse(3, ds.Tables[0].Rows[3]["PropertyValue"] == null "Wh 3" : ds.Tables[0].Rows[3]["PropertyValue"].ToString(), 0));
                  alWarehouse.Add(new eWarehouse(4, ds.Tables[0].Rows[4]["PropertyValue"] == null "Wh 4" : ds.Tables[0].Rows[4]["PropertyValue"].ToString(), 0));

     

     return alWarehouse;
    }

   

  CLIENT-SIDE
    public static ArrayList GetWarehouses(string strConn, string strWS_URL, string strTypeOfConnection, string strLanguage, bool booHasAll)
    {
       OthersServ proxy = Common.GetProxy(strWS_URL);
  
        ArrayList alWarehouse = new ArrayList(5);

        //-------Coz proxy.GetWarehouses return object[] instead of ArrayList, I just put it back to an ArrayList-------
        foreach (object obj in proxy.GetWarehouses(strConn, strLanguage, booHasAll))
         alWarehouse.Add(obj);

        return alWarehouse;
     }

    }

   public class Common
   {
    public Common()
    {
    }

    internal static OthersServ GetProxy(string strWS_URL)
    {
     OthersServ proxy =new OthersServ();
     proxy.Url = strWS_URL+"\\OthersServ.asmx";
     return proxy;
    }
   }

   

  Many many thanks

  Hi,

  For the purpose of serialization it would also need to have the parameterless contructor defined explicitly. Add the paramterless constructor in addition to your parameterized constructors and it should work fine.
