問題5
You are creating a Web application.
The Web application has a Web Form that contains a data grid named DgCustomers. You set the Web Form as asynchronous.
You write the following code segment in the code-behind file of the application.

A. Private Sub EndAsyncOperation(ByVal ar As IAsyncResult) reader = command.EndExecuteReader(ar) DgCustomers.DataSource = reader DgCustomers.DataBind() End Sub

B. Private Sub EndAsyncOperation(ByVal ar As IAsyncResult) reader = command.ExecuteReader(CommandBehavior.CloseConnection) DgCustomers.DataSource = reader DgCustomers.DataBind() End Sub

C. Private Function BeginAsyncOperation(ByVal sender As Object, ByVal e As EventArgs, ByVal cb As AsyncCallback, ByVal extradata As Object) As IAsyncResult connection = New SqlConnection("Data Source=.;Initial Catalog=Contoso;Integrated Security=True; Asynchronous Processing=True") connection.Open() command = New SqlCommand("Select * from Customers", connection) Return command.BeginExecuteReader(cb, extradata, CommandBehavior.CloseConnection) End Function

D. Private Function BeginAsyncOperation(ByVal sender As Object, ByVal e As EventArgs, ByVal cb As AsyncCallback, ByVal extradata As Object) As IAsyncResult connection = New SqlConnection("Data Source=.;Initial Catalog=Contoso;Integrated Security=True;Asynchronous Processing=True") connection.Open() command = New SqlCommand("Select * from Customers", connection) Return cb.BeginInvoke (Nothing, EndAsyncOperation, extradata) End Function
