' ...
' create SqlCeCommand cmd
' ...
Dim myParam As SqlCeParameter = cmd.Parameters.Add("@Description", SqlDbType.NVarChar)
If Not cmd.Parameters.Contains(myParam) Then
    MessageBox.Show("ERROR: no such parameter in the collection")
Else
    MessageBox.Show("match on parameter #" & cmd.Parameters.IndexOf(myParam).ToString())
End If
// ...
// create SqlCeCommand cmd
// ...
SqlCeParameter myParam = cmd.Parameters.Add("@Description", SqlDbType.NVarChar);
if (!cmd.Parameters.Contains(myParam))
    MessageBox.Show("ERROR: no such parameter in the collection");
else
    MessageBox.Show("match on parameter #" +
        cmd.Parameters.IndexOf(myParam).ToString());
