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

Syntax

声明
Public Structure Span

public struct Span

public value class Span

[<Sealed>]
type Span =  struct end

JScript supports the use of structures, but not the declaration of new ones.

The Span type exposes the following members.

Constructors

	Name	Description
	Span	Initializes a new instance of a Span with the given start point and length.

Properties

	Name	Description
	End	Gets the end of the span.
	IsEmpty	Determines whether or not this span is empty.
	Length	Gets the length of the span, which is always non-negative.
	Start	Gets the starting index of the span.

Methods

	Name	Description
	Contains(Int32)	Determines whether the position lies within the span.
	Contains(Span)	Determines whether the specified span falls completely within this span.
	Equals	Determines whether two spans are the same. (Overrides ValueType.Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	FromBounds	Initializes a new instance of a Span with the given start and end positions.
	GetHashCode	Provides a hash function for the type. (Overrides ValueType.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Intersection	Gets the intersection with the given span, or null if there is no intersection.
	IntersectsWith	Determines whether span intersects this span.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Overlap	Gets the overlap with the specified span.
	OverlapsWith	Determines whether the specified span overlaps this span.
	ToString	Provides a string representation of the span. (Overrides ValueType.ToString().)

	Equality	Determines whether two spans are the same.
	Inequality	Determines whether two spans are different.

Remarks

This structure represents an immutable integer interval that describes a range of values, from Start to End. It is closed on the left and open on the right: [Start .. End). In the context of an ITextSnapshot it represents a span of text, but the span structure itself is independent of any particular text buffer or snapshot.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
