The following example uses a DataTableMapping to Add several DataColumnMapping objects to its ColumnMappings collection, and then displays a list of those mapped source columns. This example assumes that a DataTableMapping has already been created.
public void ShowColumnMappings() { // ... // create tableMapping // ... tableMapping.ColumnMappings.Add("Category Name","DataCategory"); tableMapping.ColumnMappings.Add("Description","DataDescription"); tableMapping.ColumnMappings.Add("Picture","DataPicture"); Console.WriteLine("Column Mappings"); for(int i=0;i < tableMapping.ColumnMappings.Count;i++) { Console.WriteLine(" {0} {1}", i, tableMapping.ColumnMappings[i].ToString()); } }
