delphi - 从 Delphi XE 访问 Delphi Prism 类库

Question

我需要在 Delphi XE 中访问此 Delphi Prism 类库中的“Auth”方法:

    namespace ClassLibrary1;

    interface

    uses
      System,
      System.IO,
      System.Security.Cryptography,
      System.Runtime.InteropServices,
      System.Text;

    type
      ConsoleApp = public class
      private
        class method hashMe(input: string): string;
        class method Encrypt(clearText: string; Password: string; Salt: array of byte; iteration: Integer): string;
        class method Encrypt(clearData: array of byte; Key: array of byte; IV: array of byte): array of byte;
        class method Encrypt(clearData: array of byte; Password: string; Salt: array of byte; iteration: integer): array of byte;
        class method Decrypt(cipherText: string; Password: string; Salt: array of byte; iterations: Integer): string;
        class method Decrypt(cipherData: array of byte; Password: string; Salt: array of byte; iterations: integer): array of byte;
        class method Decrypt(cipherData: array of byte; Key: array of byte; IV: array of byte): array of byte;
      protected
      public
        [UnmanagedExport('Auth')]
        class method Auth(userName: String; userPassword: String): String;
      end;

    implementation
[...]

这对于 CrossTalk 来说非常容易，但是 CrossTalk 非常昂贵，并且此代码适用于一个宠物项目。有什么简单的方法可以做到这一点吗？

TIA

Answer 1

function Auth(userName: PAnsiChar; userPassword: PAnsiChar): PAnsiChar; stdcall; external 'ClassLibrary1.dll' 

但是在非托管/win32 代码中返回 PAnsiChar 并不是一个好主意。谁来释放字符串？
