![]() | GetType() | |
![]() | IndexOf(Object) | Gets the location of the specified DataTableMapping object within the collection. |
![]() | IndexOf(String) | Gets the location of the DataTableMapping object with the specified source table name. |
![]() | IndexOfDataSetTable(String) | Gets the location of the DataTableMapping object with the specified DataSet table name. |
![]() | InitializeLifetimeService() | Obtains a lifetime service object to control the lifetime policy for this instance.(Inherited from MarshalByRefObject.) |
![]() | Insert(Int32, DataTableMapping) | Inserts a DataTableMapping object into the DataTableMappingCollection at the specified index. |
![]() | Insert(Int32, Object) | Inserts a DataTableMapping object into the DataTableMappingCollection at the specified index. |
![]() | 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. |
![]() | RemoveAt(String) | Removes the DataTableMapping object with the specified source table name from the collection. |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | ITableMappingCollection.Add(String, String) | Adds a table mapping to the collection. |
![]() ![]() | ITableMappingCollection.GetByDataSetTable(String) | Gets the TableMapping object with the specified DataSet table name. |
![]() ![]() | ICollection.IsSynchronized | Gets a value indicating whether access to the ICollection is synchronized (thread safe). |
![]() ![]() | ICollection.SyncRoot | Gets an object that can be used to synchronize access to the ICollection. |

The following example uses an OleDbDataAdapter to AddDataTableMapping 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); }
