The ExpressionTransformationWrapper type exposes the following members.
Methods
Name | Description | |
---|---|---|
AsExpressionTransformation |
Gets a copy of the underlying ExpressionTransformation.
| |
Connect | Connects to the input reader.
A DataRowReader can then be retrieved from the DataTransformationConnection.
(Inherited from DataTransformation.) | |
ConnectCore | Connects to the input reader. A DataRowReader
can then be retrieved from the DataTransformationConnection.
