Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
A DataColumnMapping enables you to use column names in a DataTable that are different from those in the data source. The DataAdapter uses the mapping to match the columns when the tables in the DataSet or data source are updated. For more information, see Setting Up DataTable and DataColumn Mappings.
Example
[Visual Basic, C#, C++] The following example creates a DataColumnMapping object and adds it to a DataColumnMappingCollection. It then tells the user that the mapping was added to the collection and shows the Parent for the mapping.
[Visual Basic] Public Sub AddDataColumnMapping() ' ... ' create myColumnMappings ' ... Dim myNewMapping As New DataColumnMapping("Description", "DataDescription") myColumnMappings.Add(CType(myNewMapping, Object)) MessageBox.Show("column " + myNewMapping.ToString() + " added to " _ + "column mapping collection " + myColumnMappings.ToString()) End Sub [C#] public void AddDataColumnMapping() { // ... // create myColumnMappings // ... DataColumnMapping myNewMapping = new DataColumnMapping("Description","DataDescription"); myColumnMappings.Add((Object) myNewMapping); MessageBox.Show("column " + myNewMapping.ToString() + " added to " + "column mapping collection " + myColumnMappings.ToString()); } [C++] void AddDataColumnMapping() { // ... // create myColumnMappings // ... DataColumnMapping* myNewMapping = new DataColumnMapping(S"Description",S"DataDescription"); myColumnMappings->Add(static_cast<Object*>(myNewMapping)); MessageBox::Show(String::Concat( S"column ", myNewMapping->ToString(), S" added to ", S"column mapping collection ", myColumnMappings->ToString() )); }
