定义

尝试以 X.509 SubjectPublicKeyInfo 格式将当前密钥导出到所提供的缓冲区。Attempts to export the current key in the X.509 SubjectPublicKeyInfo format into a provided buffer.

public:
 override bool TryExportSubjectPublicKeyInfo(Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);
public override bool TryExportSubjectPublicKeyInfo (Span<byte> destination, out int bytesWritten);
override this.TryExportSubjectPublicKeyInfo : Span<byte> * int -> bool
Public Overrides Function TryExportSubjectPublicKeyInfo (destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

参数

destination
Span<Byte>

接收 X.509 SubjectPublicKeyInfo 数据的字节范围。The byte span to receive the X.509 SubjectPublicKeyInfo data.

bytesWritten
Int32

此方法返回时,包含一个指示写入 destination 的字节数的值。When this method returns, contains a value that indicates the number of bytes written to destination. 该参数未经初始化即被处理。This parameter is treated as uninitialized.

返回

如果 destination 具有足够的大小以接收输出,则为 true;否则为 falsetrue if destination is big enough to receive the output; otherwise, false.
