| Translate<TElement>(DbDataReader) |
Translates a DbDataReader that contains rows of entity data to objects of the requested entity type. |
| Translate<TEntity>(DbDataReader, String, MergeOption) |
Translates a DbDataReader that contains rows of entity data to objects of the requested entity type, in a specific entity set, and with the specified merge option. |
Translate<TElement>(DbDataReader)
Translates a DbDataReader that contains rows of entity data to objects of the requested entity type.
public:
generic <typename TElement>
System::Data::Objects::ObjectResult<TElement> ^ Translate(System::Data::Common::DbDataReader ^ reader);public System.Data.Objects.ObjectResult<TElement> Translate<TElement> (System.Data.Common.DbDataReader reader);member this.Translate : System.Data.Common.DbDataReader -> System.Data.Objects.ObjectResult<'Element>Public Function Translate(Of TElement) (reader As DbDataReader) As ObjectResult(Of TElement)Type Parameters
- TElement
The entity type of the data in the DbDataReader.
Parameters
- reader
- DbDataReader
The DbDataReader that contains entity data to translate into entity objects.
Returns
An enumeration of objects of type TResult.
Exceptions
When reader is null.
Remarks
The Translate method is used to translate entity data from a DbDataReader into objects of the requested type. This process is performed automatically when an ObjectQuery<T> is executed to return entity data. The Translate method enables you to execute a standard ADO.NET query against a data source and translate the returned data rows into entity objects.
The supplied DbDataReader must contain data that maps to the requested entity type.

Translate<TEntity>(DbDataReader, String, MergeOption)
Translates a DbDataReader that contains rows of entity data to objects of the requested entity type, in a specific entity set, and with the specified merge option.
public:
generic <typename TEntity>

- TEntity
The entity type of the data in the DbDataReader.
Parameters
- reader
- DbDataReader
The DbDataReader that contains entity data to translate into entity objects.
- entitySetName
- String
The entity set of the TEntity type.
- mergeOption
- MergeOption
The MergeOption to use when translated objects are added to the object context. The default is AppendOnly.
Returns
An enumeration of objects of type TResult.
Exceptions
When reader is null.
When the supplied mergeOption is not a valid MergeOption value.
When the supplied entitySetName is not a valid entity set for the TResult type.
