Examples

The following example searches for a DataColumnMapping within the collection. If the mapping exists in the collection, it is removed. If the mapping does not exist within the collection, it is added to the collection and its index is displayed. The example assumes that a DataColumnMappingCollection collection and a DataColumnMapping object have been created.

public void ChangedMyMind() 
{
    // ...
    // create mappings and mapping
    // ...
    if (mappings.Contains((Object) mapping))
        mappings.Remove((Object) mapping);
    else 
    {
        mappings.Add((Object) mapping);
        Console.WriteLine("Index of new mapping: "
            + mappings.IndexOf((Object) mapping));
    }
}
Public Sub ChangedMyMind()
    ' ...
    ' create mappings and mapping
    ' ...
    If mappings.Contains(CType(mapping, Object)) Then
        mappings.Remove(CType(mapping, Object))
    Else
        mappings.Add(CType(mapping, Object))
        Console.WriteLine("Index of new mapping: " + _
           mappings.IndexOf(CType(mapping, Object)).ToString())
