Array2DTGetElementReference Method

Gets the reference to the element at the specified indices. Parameter order is the same as in case of a regular two-dimensional array.

Namespace: KGySoft.Collections
Assembly: KGySoft.CoreLibraries (in KGySoft.CoreLibraries.dll) Version: 10.0.0

C#

public ref T GetElementReference(
	int y,
	int x
)

VB

Public Function GetElementReference ( 
	y As Integer,
	x As Integer
) As T

C++

public:
T% GetElementReference(
	int y, 
	int x
)

F#

member GetElementReference : 
        y : int * 
        x : int -> 'T

Parameters

y Int32: The Y-coordinate (row index) of the item to get the reference for.
x Int32: The X-coordinate (column index) of the item to get the reference for.

Return Value

T
The reference to the element at the specified coordinates.

Remarks

Though this method does not validate the coordinates separately, it does not allow indexing beyond the Length of the underlying Buffer. To omit also the length check, allowing to get the reference to any element in the whole UnderlyingArray, use the GetElementReferenceUnchecked method instead.

Note

This method returns a value by reference. If this library is used by an older compiler that does not support such members, use the indexer instead.

Exceptions

IndexOutOfRangeException	The specified indices refer to an item outside the bounds of the underlying Buffer.
VerificationException	.NET Framework only: you execute this method in a partially trusted AppDomain that does not allow executing unverifiable code.
