amrameshreddy.blog.com368 CHAPTER 11 ■ WORKING WITH DATAramrameshreddy.blog.comThe code for the client where the service is invoked is fairly straightforward, as shown inListing 11-22. Because you do not have any persistence storage, the tickers are hard-coded andthe service is then invoked. The result from the service is bound to the data grid on the form.Listing 11-22. Calling the Service and Binding Data Contract to the Gridprivate void buttonGetPortfolio_Click(object sender, EventArgs e){this.Cursor = Cursors.WaitCursor;}//We hard-code an array of a few stocks that we want the service//to return. In the real world, this would be retrieved//from some persistent storestring[] stocks = { "INTU", "MSFT", "GOOG", "IBM" };//Invoke the ServiceStockQuote[] portfolio = theService.GetPortfolio(stocks);//Bind the data contract returned by the service to the grid.BindData(ref dataGridView, portfolio);private void BindData(ref DataGridView dataGrid, object data){BindingSource bindingSource = new BindingSource();bindingSource.DataSource = data;}dataGrid.DataSource = bindingSource;dataGrid.Columns["ExtensionData"].Visible = false;As stated earlier, the client consumes two versions of the service. When you talk to thesimpler version 1 of the service, you can see the result for both the GetPortfolio and GetStockoperations in Figure 11-3 and Figure 11-4, respectively. Only three elements are known by theclient—LastTrade, CompanyName, and TickerSymbol. To implement this old version, include theQuoteService1.cs file in the solution.ramrameshreddyramrameshreddy
