Question

In short: Trying to write a wcf service for a winform-app that invokes a stored procedure on a webserver.
So far no problem – my service exposes the method “execStp(string nameOfStoredProcedure, stpParamList parameterList)”

 [OperationContract]
        int execStp(string stpName, srsWcfLib.Utilities.stpParamList paramList);

where stpParamList is another class holding of a third class stpParams (which basically holds a name/value pair of an SqlParameter

To add parameters to the list, I wrote a method in the second class

public void addParameter(string ParamName, object ParamValue)
        {
            this._Parameters.Add(new stpParam(ParamName, ParamValue));
        } 
List<stpParam> _Parameters = new List<stpParam>();

    [DataMember]
    public List<stpParam> Parameters
    {
        get { return _Parameters; }
        set { _Parameters = value; }
    }

When instantiating the List-class in the win-app

stpParamList stpParams = new stpParamList();

I can access stpParams.Parameters, but NOT stpParams.addParameter (name, value);

What am I missing (obviously)…?

Thank you,
Reinhard

WCF only brings over the properties to the client, not the functions. I forget the term they use, but it is basically just a property/field dump that gets sent through.

To solve this, reference the same Entity library in the client, and under “configure WCF Service” check “reuse reference” for that library.
