This sample demonstrates how to iterate through fields in a row using
FieldCount property.
public void FetchResults(ZohoBooksConnection ZohoBooksConnection)
{
ZohoBooksCommand cmd = new ZohoBooksCommand("SELECT * FROM Accounts");
cmd.FetchSize = 100;
cmd.Connection = ZohoBooksConnection;
ZohoBooksConnection.Open();
try
{
ZohoBooksDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
for (int i=0;i<reader.FieldCount;i++)
{
Console.Write("\t"+reader[i]);
}
Console.WriteLine();
}
}
finally
{
ZohoBooksConnection.Close();
}
}
Public Sub FetchResults(ByVal ZohoBooksConnection As ZohoBooksConnection)
Dim cmd As ZohoBooksCommand = New ZohoBooksCommand("SELECT * FROM Accounts")
cmd.FetchSize = 100
cmd.Connection = ZohoBooksConnection
ZohoBooksConnection.Open()
Try
Dim reader As ZohoBooksDataReader = 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
ZohoBooksConnection.Close()
End Try
End Sub
