X509Certificate.GetHashCode 方法

定義

將 X.509v3 憑證的雜湊程式碼傳回為整數。Returns the hash code for the X.509v3 certificate as an integer.

public:
 override int GetHashCode();
public override int GetHashCode ();
override this.GetHashCode : unit -> int
Public Overrides Function GetHashCode () As Integer

傳回

做為整數的 X.509 憑證雜湊碼。The hash code for the X.509 certificate as an integer.

範例

下列範例會使用 GetHashCode 方法來傳回憑證雜湊碼的整數標記法,並將它顯示在主控台中。The following example uses the GetHashCode method to return an integer representation of a certificate's hash code and displays it to the console.

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int 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.
   int results = cert->GetHashCode();
   
   // Display the value to the console.
   Console::WriteLine( results );
}


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.
        int results = cert.GetHashCode();
       
        // 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 Integer = cert.GetHashCode()
      
      ' Display the value to the console.
      Console.WriteLine(results)
   End Sub 
End Class 

備註

如果 x.509 憑證雜湊是超過4個位元組的陣列,則第四個位元組之後的任何位元組都不會出現在這個整數表示中。If the X.509 certificate hash is an array of more than 4 bytes, any byte after the fourth byte is not seen in this integer representation.
