Methods

AsBytes<T>(Span<T>)	Casts a Span<T> of one primitive type T to Span<T> of bytes.
AsSpan2D<T>(Span<T>, Int32, Int32, Int32, Int32)	Returns a Span2D<T> instance wrapping the underlying data for the given Span<T> instance.
AsSpan2D<T>(Span<T>, Int32, Int32)	Returns a Span2D<T> instance wrapping the underlying data for the given Span<T> instance.
Cast<TFrom,TTo>(Span<TFrom>)	Casts a Span<T> of one primitive type TFrom to another primitive type TTo.
CopyTo<T>(Span<T>, RefEnumerable<T>)	Copies the contents of a given Span<T> into destination RefEnumerable<T> instance.
Count<T>(Span<T>, T)	Counts the number of occurrences of a given value into a target Span<T> instance.
DangerousGetReference<T>(Span<T>)	Returns a reference to the first element within a given Span<T>, with no bounds checks.
DangerousGetReferenceAt<T>(Span<T>, Int32)	Returns a reference to an element at a specified index within a given Span<T>, with no bounds checks.
DangerousGetReferenceAt<T>(Span<T>, IntPtr)	Returns a reference to an element at a specified index within a given Span<T>, with no bounds checks.
Enumerate<T>(Span<T>)	Enumerates the items in the input Span<T> instance, as pairs of reference/index values. This extension should be used directly within a foreach loop: Span<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.
GetDjb2HashCode<T>(Span<T>)	Gets a content hash from the input Span<T> instance using the Djb2 algorithm. For more info, see the documentation for GetDjb2HashCode<T>(ReadOnlySpan<T>).
IndexOf<T>(Span<T>, T)	Gets the index of an element of a given Span<T> from its reference.
Tokenize<T>(Span<T>, T)	Tokenizes the values in the input Span<T> instance using a specified separator. This extension should be used directly within a foreach loop: Span<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.
TryCopyTo<T>(Span<T>, RefEnumerable<T>)	Attempts to copy the contents of a given Span<T> into destination RefEnumerable<T> instance.
