Examples

The following example searches for a SqlCeParameter with a given ParameterName within a SqlCeParameterCollection. If the parameter exists, the example displays the index of the parameter. If the parameter does not exist, the example displays an error. This example assumes that a SqlCeCommand has already been created.

' ...
' create SqlCeCommand cmd
' ...
If Not cmd.Parameters.Contains("Description") Then
    MessageBox.Show("ERROR: no such parameter in the collection")
Else
    MessageBox.Show("match on parameter #" & cmd.Parameters.IndexOf("Description").ToString())
End If

// ...
// create SqlCeCommand cmd
// ...
if (!cmd.Parameters.Contains("Description"))
    MessageBox.Show("ERROR: no such parameter in the collection");
else
    MessageBox.Show("match on parameter #" +
        cmd.Parameters.IndexOf("Description").ToString());
