Examples
The following example searches for an OdbcParameter with a given ParameterName within an OdbcParameterCollection. If the parameter exists, the example displays the name and index of the parameter. If the parameter does not exist, the example displays an error. This example assumes that an OdbcParameterCollection has already been created.
public void SearchParameters()
{
// ...
// create OdbcParameterCollection parameterCollection
// ...
if (!parameterCollection.Contains("Description"))
Console.WriteLine("ERROR: no such parameter in the collection");
else
Console.WriteLine("Name: " + parameterCollection["Description"].ToString() +
"Index: " + parameterCollection.IndexOf("Description").ToString());
}
Public Sub SearchParameters()
' ...
' create OdbcParameterCollection parameterCollection
' ...
If Not parameterCollection.Contains("Description") Then
Console.WriteLine("ERROR: no such parameter in the collection")
Else
Console.WriteLine("Name: " & parameterCollection("Description").ToString() & _
"Index: " & parameterCollection.IndexOf("Description").ToString())
End If
