Intersection(SnapshotSpan)

Computes the intersection with the given SnapshotSpan, or null if there is no intersection.

public:
 Nullable<Microsoft::VisualStudio::Text::SnapshotSpan> Intersection(Microsoft::VisualStudio::Text::SnapshotSpan snapshotSpan);

public Microsoft.VisualStudio.Text.SnapshotSpan? Intersection (Microsoft.VisualStudio.Text.SnapshotSpan snapshotSpan);

member this.Intersection : Microsoft.VisualStudio.Text.SnapshotSpan -> Nullable<Microsoft.VisualStudio.Text.SnapshotSpan>

Public Function Intersection (snapshotSpan As SnapshotSpan) As Nullable(Of SnapshotSpan)

Parameters

snapshotSpan

SnapshotSpan

The span to check.

Returns

Nullable<SnapshotSpan>

The intersection of the spans, or null if the intersection is empty.

Exceptions

ArgumentException

snapshotSpan does not refer to the same snapshot.

Remarks

Two spans intersect if they have positions in common, or if the end of one span coincides with the start of the other span, and neither is empty.

Intersection(Span)

Computes the intersection with the given span, or null if there is no intersection.

public:
 Nullable<Microsoft::VisualStudio::Text::SnapshotSpan> Intersection(Microsoft::VisualStudio::Text::Span simpleSpan);

public Microsoft.VisualStudio.Text.SnapshotSpan? Intersection (Microsoft.VisualStudio.Text.Span simpleSpan);

member this.Intersection : Microsoft.VisualStudio.Text.Span -> Nullable<Microsoft.VisualStudio.Text.SnapshotSpan>

Public Function Intersection (simpleSpan As Span) As Nullable(Of SnapshotSpan)

Parameters

simpleSpan

Span

The span to check.

Returns

Nullable<SnapshotSpan>

The intersection of the spans, or null if the intersection is empty.
