Parameters
- dataset
- The dataset that holds information on a DICOM basic directory.
Type Parameters
- T
- The entity type of the query.
Return Value
A object that provides LINQ based access to a DICOM basic directory.Example
This example will show how to perform serveral different types of LINQ based queries on a DICOM basic directory.
Remarks
This extension method represents a query that returns a collection of zero or more objects of a specific type. A valid DICOMDIR must be present in the dataset parameter before a query can be executed. A DICOMDIR query will be executed in the following scenarios:
- When it is acted upon, such as during a foreach(C#) or For Each (Visual Basic) enumeration.
- When it is assigned to fill a List<T> collection.
The following operations are provided by the DICOMDIR LINQ Provider.
- SelectMany
- String Methods (Contains, StartWith, and EndsWith)
- LINQ Projection
- Subqueries
