The GeoHash type exposes the following members.

Properties

	Name	Description
	Adjacent	returns the 8 adjacent hashes for this one. They are in the following order: N, NE, E, SE, S, SW, W, NW
	BoundingBox	Get BoundingBox for this GeoHash
	BoundingBoxCenterPoint	return the center of this s bounding box. this is rarely the same point that was used to build the hash.
	CharacterPrecision	Returns the number of characters that represent this hash.
	EasternNeighbour	Nearest GeoHash Neighbor to the East
	LongValue	Int64 representation of this GeoHash
	NorthernNeighbour	Nearest GeoHash Neighbor to the North
	Point	returns the that was originally used to set up this. If it was built from a base32-, this is the center point of the bounding box.
	SignificantBits	how many significant bits are there in this ?
	SouthernNeighbour	Nearest GeoHash Neighbor to the South
	WesternNeighbour	Nearest GeoHash Neighbor to the West

Methods

	Name	Description
	CompareTo
	Contains	find out if the given point lies within this hashes bounding box. Note: this operation checks the bounding boxes coordinates, i.e. does not use the s special abilities.s
	EnclosesCircleAroundPoint	?
	Equals	Determines whether the specified object is equal to the current object. (Overrides ObjectEquals(Object).)
	FromBinaryString	Recreates a GeoHash from a string of 0's and 1's
	FromGeohashString	build a new from a base32-encoded . This will also set up the hashes bounding box and other values, so it can also be used with functions like within().
	FromLongValue	Creates a GeoHash from a long value
	FromOrd
	GeoHashStringWithCharacterPrecision	This method uses the given number of characters as the desired precision value. The hash can only be 64bits long, thus a maximum precision of 12 characters can be achieved.
	GetHashCode	Serves as the default hash function. (Overrides ObjectGetHashCode.)
	Next	?
	Next(Int32)	?
	Ord	?
	Prev	?
	StepsBetween	Counts the number of geohashes contained between the two (ie how many times next() is called to increment from one to two) This value depends on the number of significant bits.
	ToBase32	get the base32 string for this . this method only makes sense, if this hash has a multiple of 5 significant bits.
	ToBinaryString	Get binary String representation of this GeoHash
	ToString	Returns a string that represents the current object. (Overrides ObjectToString.)
	withBitPrecision	create a new with the given number of bits accuracy. This at the same time defines this hash's bounding box.
	WithBitPrecision	create a new with the given number of bits accuracy. This at the same time defines this hash's bounding box.
	WithCharacterPrecision	This method uses the given number of characters as the desired precision value. The hash can only be 64bits long, thus a maximum precision of 12 characters can be achieved.
	Within	returns true if this is within the given geohash bounding box.
