Assembly: Microsoft.VisualStudio.Text.Data (in Microsoft.VisualStudio.Text.Data.dll)

Syntax

C++

ReadOnlyCollection<SnapshotPoint>^ MapToSourceSnapshots(
	int position
)

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.
