|
|
Insert(Int32, Object) | Inserts a DataTableMapping object into the DataTableMappingCollection at the specified index. |
|
|
MemberwiseClone() | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
|
|
Remove(DataTableMapping) | Removes the specified DataTableMapping object from the collection. |
|
|
Remove(Object) | Removes the specified DataTableMapping object from the collection. |
|
|
RemoveAt(Int32) | Removes the DataTableMapping object located at the specified index from the collection. |
|

|
|
ITableMappingCollection.Item | Gets or sets the instance of ITableMapping with the specified SourceTable name. |
The following example uses an OleDbDataAdapter to Add DataTableMapping objects to its TableMappings collection, and then displays a list of those mapped source tables. This example assumes that an OleDbDataAdapter has already been created.
public void ShowTableMappings() { // ... // create adapter // ... adapter.TableMappings.Add("Categories","DataCategories"); adapter.TableMappings.Add("Orders","DataOrders"); adapter.TableMappings.Add("Products","DataProducts"); string message = "Table Mappings:\n"; for(int i=0;i < adapter.TableMappings.Count;i++) { message += i.ToString() + " " + adapter.TableMappings[i].ToString() + "\n"; } Console.WriteLine(message); }
