 bool TryExportCertificatePems(Span<char> destination, [Runtime::InteropServices::Out] int % charsWritten);

public bool TryExportCertificatePems (Span<char> destination, out int charsWritten);

member this.TryExportCertificatePems : Span<char> * int -> bool

Public Function TryExportCertificatePems (destination As Span(Of Char), ByRef charsWritten As Integer) As Boolean

参数

destination

Span<Char>

接收 PEM 编码证书的缓冲区。

charsWritten

Int32

此方法返回时，写入到 destination的字符总数。

返回

Boolean

注解

A PEM-encoded X.509 certificate collection will contain certificates where each certificate begins with -----BEGIN CERTIFICATE----- and ends with -----END CERTIFICATE-----, with the base64 encoded DER contents of the certificate between the PEM boundaries. Each certificate is separated by a single line-feed character.

          Certificates are encoded according to the IETF RFC 7468 "strict" encoding rules.
