Examples
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);
}
Public Sub ShowTableMappings()
' ...
' create adapter
' ...
adapter.TableMappings.Add("Categories", "DataCategories")
adapter.TableMappings.Add("Orders", "DataOrders")
adapter.TableMappings.Add("Products", "DataProducts")
Dim message As String = "Table Mappings:" & ControlChars.Cr
Dim i As Integer
For i = 0 To adapter.TableMappings.Count - 1
message &= i.ToString() & " " _
& adapter.TableMappings(i).ToString() & ControlChars.Cr
Next i
Console.WriteLine(message)
End Sub
Constructors
DataTableMappingCollection() |
Initializes a new instance of the DataTableMappingCollection class. This new instance is empty, that is, it does not yet contain any DataTableMapping objects. |
Properties
Count |
Gets the number of DataTableMapping objects in the collection. |
Item[Int32] |
Gets or sets the DataTableMapping object at the specified index. |
Item[String] |
Gets or sets the DataTableMapping object with the specified source table name. |
Methods
Add(Object) |
Adds an Object that is a table mapping to the collection. |
Add(String, String) |
Adds a DataTableMapping object to the collection when given a source table name and a DataSet table name. |
AddRange(Array) |
Copies the elements of the specified Array to the end of the collection. |
AddRange(DataTableMapping[]) |
