Syntax

'Declaration
Public Function FromDsc(Of T) ( _
    fileSetName As String _
) As IQueryable(Of T)

public IQueryable<T> FromDsc<T> (

J# supports the use of generic APIs, but not the declaration of new ones.

JScript does not support generic types or methods.

T
The type of the records in the file set that you want to open. For example, the LineRecord structure, if your file set consists of lines of text.

Parameters

fileSetName
A String that specifies the name of the DSC file set that you want to open.

Return Value

An IQueryable object that represents the data in the file set and that is associated with the LINQ to HPC query provider.

Remarks

This method provides you with the data from a DSC file set in the form of a queryable type that you can use as the data source in an LINQ to HPC query.

Platform Note: This method was introduced in Windows HPC Server 2008 R2 with Service Pack 2 (SP2) and is not supported in previous versions.
