Methods

AsMemory<T>(T[,,], Int32)	Creates a new instance of the Memory<T> struct wrapping a layer in a 3D array.
AsMemory<T>(T[,,])	Creates a new Memory<T> over an input 3D T array.
AsMemory<T>(T[,])	Creates a new Memory<T> over an input 2D T array.
AsMemory2D<T>(T[,,], Int32)	Creates a new instance of the Memory2D<T> struct wrapping a layer in a 3D array.
AsMemory2D<T>(T[,], Int32, Int32, Int32, Int32)	Creates a new Memory2D<T> over an input 2D T array.
AsMemory2D<T>(T[,])	Creates a new Memory2D<T> over an input 2D T array.
AsSpan<T>(T[,,], Int32)	Creates a new instance of the Span<T> struct wrapping a layer in a 3D array.
AsSpan<T>(T[,,])	Creates a new Span<T> over an input 3D T array.
AsSpan<T>(T[,])	Creates a new Span<T> over an input 2D T array.
AsSpan2D<T>(T[,,], Int32)	Creates a new instance of the Span2D<T> struct wrapping a layer in a 3D array.
AsSpan2D<T>(T[,], Int32, Int32, Int32, Int32)	Creates a new Span2D<T> over an input 2D T array.
AsSpan2D<T>(T[,])	Creates a new Span2D<T> over an input 2D T array.
Count<T>(T[,,], T)	Counts the number of occurrences of a given value into a target 3D T array instance.
Count<T>(T[,], T)	Counts the number of occurrences of a given value into a target 2D T array instance.
Count<T>(T[], T)	Counts the number of occurrences of a given value into a target T array instance.
DangerousGetReference<T>(T[,,])	Returns a reference to the first element within a given 3D T array, with no bounds checks.
DangerousGetReference<T>(T[,])	Returns a reference to the first element within a given 2D T array, with no bounds checks.
DangerousGetReference<T>(T[])	Returns a reference to the first element within a given T array, with no bounds checks.
DangerousGetReferenceAt<T>(T[,,], Int32, Int32, Int32)	Returns a reference to an element at a specified coordinate within a given 3D T array, with no bounds checks.
DangerousGetReferenceAt<T>(T[,], Int32, Int32)	Returns a reference to an element at a specified coordinate within a given 2D T array, with no bounds checks.
DangerousGetReferenceAt<T>(T[], Int32)	Returns a reference to an element at a specified index within a given T array, with no bounds checks.
Enumerate<T>(T[])	Enumerates the items in the input T array instance, as pairs of reference/index values. This extension should be used directly within a foreach loop: int[] numbers = new[] { 1, 2, 3, 4, 5, 6, 7 }; foreach (var item in numbers.Enumerate()) { // Access the index and value of each item here... int index = item.Index; ref int value = ref item.Value; } The compiler will take care of properly setting up the foreach loop with the type returned from this method.
GetColumn<T>(T[,], Int32)	Returns a RefEnumerable<T> that returns the items from a given column in a given 2D T array instance. This extension should be used directly within a foreach loop: int[,] matrix = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; foreach (ref int number in matrix.GetColumn(1)) { // Access the current number by reference here... } The compiler will take care of properly setting up the foreach loop with the type returned from this method.
GetDjb2HashCode<T>(T[,,])	Gets a content hash from the input 3D T array instance using the Djb2 algorithm. For more info, see the documentation for GetDjb2HashCode<T>(ReadOnlySpan<T>).
GetDjb2HashCode<T>(T[,])	Gets a content hash from the input 2D T array instance using the Djb2 algorithm. For more info, see the documentation for GetDjb2HashCode<T>(ReadOnlySpan<T>).
GetDjb2HashCode<T>(T[])	Gets a content hash from the input T array instance using the Djb2 algorithm. For more info, see the documentation for GetDjb2HashCode<T>(ReadOnlySpan<T>).
GetRow<T>(T[,], Int32)	Returns a RefEnumerable<T> over a row in a given 2D T array instance.
GetRowMemory<T>(T[,], Int32)	Returns a Memory<T> over a row in a given 2D T array instance.
GetRowSpan<T>(T[,], Int32)	Returns a Span<T> over a row in a given 2D T array instance.
IsCovariant<T>(T[,,])	Checks whether or not a given T array is covariant.
IsCovariant<T>(T[,])	Checks whether or not a given T array is covariant.
IsCovariant<T>(T[])	Checks whether or not a given T array is covariant.
Tokenize<T>(T[], T)	Tokenizes the values in the input T array instance using a specified separator. This extension should be used directly within a foreach loop: char[] text = "Hello, world!".ToCharArray(); foreach (var token in text.Tokenize(',')) { // Access the tokens here... } The compiler will take care of properly setting up the foreach loop with the type returned from this method.
