  • Here is sample how to work with output parameters,



    Basically you need to declare parameters in your code and set Direction property of output parameters to ParameterDirection.Output or ParameterDirection.InputOutput

  • Now i want to write the function in BLL in order to receive ouput parameter from procedure execution


    private Merp_CusListTableAdapter _CuslistAdapter = null;

    protected Merp_CusListTableAdapter Adapter




    if (_CuslistAdapter == null)

    _CuslistAdapter = new Merp_CusListTableAdapter();

    return _CuslistAdapter;





    public Int64 CreateCusID(String Cusname)


    long CusID;

    Adapter.CreateCustomerID(Cusname,ref CusID);

    // Int64 CusID = 30000;

    return CusID;



    But it is not run, how can i fix it?

  • Have you created collection of the parameters in your code to pass it to SqlCommand that selects data? After you call Fill method of your DataAdapter, you need to read output parameter to get that data. I believe sample I have posted shows how to do this.
