Take a string formatted as a 6, 8 or 10 figure OS grid reference (e.g. "TG514131") and create a new OSRef object that represents that grid reference. The first character must be H, N, S, O or T. The second character can be any uppercase character from A through Z excluding I.

public OSRef(
	string gridRef
)

Public Sub New ( 
	gridRef As String
)

public:
OSRef(
	String^ gridRef
)

new : 
        gridRef : string -> OSRef
