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)

public sealed class DataColumnMapping : MarshalByRefObject, 
	IColumnMapping, ICloneable

The DataColumnMapping type exposes the following members.

Public methodSupported by the XNA FrameworkDataColumnMapping()Initializes a new instance of the DataColumnMapping class.
Public methodSupported by the XNA FrameworkDataColumnMapping(String, String)Initializes a new instance of the DataColumnMapping class with the specified source column name and DataSet column name to map to.

Public propertySupported by the XNA FrameworkDataSetColumnGets or sets the name of the column within the DataSet to map to.
Public propertySupported by the XNA FrameworkSourceColumnGets or sets the name of the column within the data source to map from. The name is case-sensitive.

Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodSupported by the XNA FrameworkEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetDataColumnBySchemaAction(DataTable, Type, MissingSchemaAction)Gets a DataColumn from the given DataTable using the MissingSchemaAction and the DataSetColumn property.
Public methodStatic memberSupported by the XNA FrameworkGetDataColumnBySchemaAction(String, String, DataTable, Type, MissingSchemaAction)A static version of GetDataColumnBySchemaAction that can be called without instantiating a DataColumnMapping object.
Public methodSupported by the XNA FrameworkGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodSupported by the XNA FrameworkGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodSupported by the XNA FrameworkToStringConverts the current SourceColumn name to a string. (Overrides Object.ToString().)

Explicit interface implemetationPrivate methodSupported by the XNA FrameworkICloneable.CloneCreates a new object that is a copy of the current instance.

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.

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());
