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