Assembly: Microsoft.VisualStudio.Text.Data (in Microsoft.VisualStudio.Text.Data.dll)
Syntax
'宣言
Function MapToSourceSnapshots ( _
position As Integer _
) As ReadOnlyCollection(Of SnapshotPoint)
ReadOnlyCollection<SnapshotPoint> MapToSourceSnapshots(
int position
)
ReadOnlyCollection<SnapshotPoint>^ MapToSourceSnapshots(
int position
)
abstract MapToSourceSnapshots :
position:int -> ReadOnlyCollection<SnapshotPoint>
function MapToSourceSnapshots(
position : int
) : ReadOnlyCollection<SnapshotPoint>
Parameters
- position
Type: System.Int32
The position in the projection snapshot.
Return Value
Type: System.Collections.ObjectModel.ReadOnlyCollection<SnapshotPoint>
A read-only collection of snapshot points to which the position maps. This collection contains one snapshot point unless the position lies on a source span seam, in which case it can contain two or more points.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | position is less than zero or greater than or equal to the length of the snapshot. |
Remarks
In general, a source span seam occurs at the end of a source span of nonzero length and the beginning of a source span of nonzero length, and coincides with zero or more source spans of zero length. Every span on a seam has a point in the result collection.
