The following example searches for an instance of the derived class, DataColumnMapping, with the given source column name within a DataColumnMappingCollection collection. If the DataColumnMapping exists, the example displays the name and the index of the mapping. If the mapping does not exist, the example displays an error. This example assumes that a DataColumnMappingCollection collection has been created.

public void FindDataColumnMapping() 
{
    // ... 
    // create columnMappings 
    // ... 
    if (!columnMappings.Contains("Description"))
        Console.WriteLine("Error: no such table in collection.");
    else
    {
        Console.WriteLine("Name {0}", 
            columnMappings["Description"].ToString());
        Console.WriteLine("Index: {0}", 
            columnMappings.IndexOf("Description").ToString());
    }
}
