public static bool IsValid (byte value);

static member IsValid : byte -> bool

Public Shared Function IsValid (value As Byte) As Boolean

Parameters

value

Byte

The value to inspect.

Returns

Boolean

true if value is ASCII, false otherwise.

IsValid(Char)

Source:

Ascii.cs

Determines whether the provided value is ASCII char.

public:
 static bool IsValid(char value);

static member IsValid : char -> bool

Public Shared Function IsValid (value As Char) As Boolean

Parameters

value

Char

The value to inspect.

Returns

Boolean

true if value is ASCII, false otherwise.

IsValid(ReadOnlySpan<Byte>)

Source:

Ascii.cs

Determines whether the provided value contains only ASCII bytes.

public:
 static bool IsValid(ReadOnlySpan<System::Byte> value);
