定義

以字串形式回傳此 X.509v3 憑證的關鍵演算法資訊。

public:
 virtual System::String ^ GetKeyAlgorithm();
public virtual string GetKeyAlgorithm();
abstract member GetKeyAlgorithm : unit -> string
override this.GetKeyAlgorithm : unit -> string
Public Overridable Function GetKeyAlgorithm () As String

傳回

這份 X.509 憑證的關鍵演算法資訊以字串形式呈現。

例外狀況

憑證上下文無效。

範例

以下範例使用 GetKeyAlgorithm 此方法取得憑證金鑰演算法的字串格式,並顯示給主控台。

using System;
using System.Security.Cryptography.X509Certificates;

public class X509
{
    public static void Main()
    {
        // The path to the certificate.
        string Certificate =  "Certificate.cer";

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = X509Certificate.CreateFromCertFile(Certificate);

        // Get the value.
        string results = cert.GetKeyAlgorithm();

        // Display the value to the console.
        Console.WriteLine(results);
    }
}
Imports System.Security.Cryptography.X509Certificates




Public Class X509
   
   
   Public Shared Sub Main()
      
      ' The path to the certificate.
      Dim Certificate As String = "Certificate.cer"
      
      ' Load the certificate into an X509Certificate object.
      Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate)
      
      ' Get the value.
      Dim results As String = cert.GetKeyAlgorithm()
      
      ' Display the value to the console.
      Console.WriteLine(results)
   End Sub  
End Class
