Definition

Namespace:

System.Buffers.Text

Assembly:

Microsoft.Bcl.Memory.dll

Package:

Microsoft.Bcl.Memory v9.0.0-rc.2.24473.5

Decodes the span of unicode ASCII chars represented as Base64Url into binary data.

public:
 static bool TryDecodeFromChars(ReadOnlySpan<char> source, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);

public static bool TryDecodeFromChars (ReadOnlySpan<char> source, Span<byte> destination, out int bytesWritten);

static member TryDecodeFromChars : ReadOnlySpan<char> * Span<byte> * int -> bool

Public Shared Function TryDecodeFromChars (source As ReadOnlySpan(Of Char), destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

Parameters

source

ReadOnlySpan<Char>

The input span which contains ASCII chars in Base64Url that needs to be decoded.

destination

Span<Byte>

The output span which contains the result of the operation, i.e. the decoded binary data.

bytesWritten

Int32

When this method returns, contains the number of bytes written into the output span. This can be used to slice the output for subsequent calls, if necessary. This parameter is treated as uninitialized.

Returns

Boolean

true if bytes decoded successfully; false if destination is too small.

Exceptions

FormatException

source contains an invalid Base64Url character,

more than two padding characters, or a non white space character among the padding characters.
