This sample demonstrates how to iterate through fields in a row using
FieldCount property.
public void FetchResults(FreshBooksConnection freshbooksConnection)
{
FreshBooksCommand cmd = new FreshBooksCommand("SELECT * FROM Client");
cmd.FetchSize = 100;
cmd.Connection = freshbooksConnection;
freshbooksConnection.Open();
try
{
FreshBooksDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
for (int i=0;i<reader.FieldCount;i++)
{
Console.Write("\t"+reader[i]);
}
Console.WriteLine();
}
}
finally
{
freshbooksConnection.Close();
}
}
Public Sub FetchResults(ByVal freshbooksConnection As FreshBooksConnection)
Dim cmd As FreshBooksCommand = New FreshBooksCommand("SELECT * FROM Client")
cmd.FetchSize = 100
cmd.Connection = freshbooksConnection
freshbooksConnection.Open()
Try
Dim reader As FreshBooksDataReader = cmd.ExecuteReader()
While reader.Read()
Dim i
For i = 0 To reader.FieldCount - 1
Console.Write(String.Concat(" ", reader(i)))
Next i
Console.WriteLine()
End While
Finally
freshbooksConnection.Close()
End Try
End Sub
