X500DistinguishedName.Format(Boolean) メソッド

定義

名前空間:

System.Security.Cryptography.X509Certificates

アセンブリ:

System.Security.Cryptography.dll

ソース:

X500DistinguishedName.cs

X500 の識別名を書式設定して返します。識別名を印刷したり、テキスト ウィンドウやコンソールに出力するときに使用します。

public:
 override System::String ^ Format(bool multiLine);

public override string Format (bool multiLine);

override this.Format : bool -> string

Public Overrides Function Format (multiLine As Boolean) As String

パラメーター

multiLine

Boolean

戻り値の文字列にキャリッジ リターンを含める場合は true を、それ以外の場合は false を指定します。

戻り値

String

X500 識別名を表す、書式設定済みの文字列。

例

X500DistinguishedName クラスを使用するコード例を次に示します。
