override this.TryExportRSAPublicKey : Span<byte> * int -> bool

Public Overridable Function TryExportRSAPublicKey (destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

Parameters

destination: Span<Byte>

The byte span to receive the PKCS#1 RSAPublicKey data.

bytesWritten: Int32

When this method returns, contains a value that indicates the number of bytes written to destination. This parameter is treated as uninitialized.

Returns

Boolean

true if destination is big enough to receive the output; otherwise, false.
