DataColumnMapping Class
Contains a generic column mapping for an object that inherits from DataAdapter. This class cannot be inherited.
Namespace: System.Data.Common
Assembly: System.Data (in System.Data.dll)
The DataColumnMapping type exposes the following members.
| Name | Description | |
|---|---|---|
 | DataColumnMapping() | Initializes a new instance of the DataColumnMapping class. |
| DataColumnMapping(String, String) | Initializes a new instance of the DataColumnMapping class with the specified source column name and DataSet column name to map to. |
| Name | Description | |
|---|---|---|
| DataSetColumn | Gets or sets the name of the column within the DataSet to map to. |
| SourceColumn | Gets or sets the name of the column within the data source to map from. The name is case-sensitive. |
| Name | Description | |
|---|---|---|
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetDataColumnBySchemaAction(DataTable, Type, MissingSchemaAction) | Gets a DataColumn from the given DataTable using the MissingSchemaAction and the DataSetColumn property. |
| GetDataColumnBySchemaAction(String, String, DataTable, Type, MissingSchemaAction) | A static version of GetDataColumnBySchemaAction that can be called without instantiating a DataColumnMapping object. |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| ToString | Converts the current SourceColumn name to a string. (Overrides Object.ToString().) |
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 DataAdapter DataTable and DataColumn Mappings (ADO.NET).
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.
public void AddDataColumnMapping() { // ... // create columnMappings // ... DataColumnMapping mapping = new DataColumnMapping("Description","DataDescription"); columnMappings.Add((Object) mapping); Console.WriteLine("Column {0} added to column mapping collection {1}.", mapping.ToString(), columnMappings.ToString()); }
