在C++中有結構與聯合，因此任務是將此結構轉換爲C＃代碼。我必須轉換2天。我無法正確設置[FieldOffset（0）]屬性。如何將C++聯合轉換爲C＃結構

任何人都可以幫助將此結構轉換爲聯合？謝謝！

編輯這是我轉換到C＃代碼。但它給出錯誤「附加信息：無法從程序集'ProjectName，版本= 1.0.0.0，Culture = neutral，PublicKeyToken = null'加載類型'Common.dataunion'，因爲它包含偏移量爲0的對象字段未正確對齊或被非對象字段重疊「。

public struct dataunion 
     {  
      [FieldOffset(0)] 
      public request_set_integrity REQUEST_INTEGRITY; 
      [FieldOffset(0)] 
      public _request_update REQUEST_UPDATE; 
      [FieldOffset(0)] 
      public response_dna RESPONSE_DNA; 
      [FieldOffset(0)] 
      public request_setinfo REQUEST_SETINFO; 
      [FieldOffset(0)] 
      public byte[] m_reason; 
      [FieldOffset(0)] 
      public response_realtime RESPONSE_REALTIME; 
      [FieldOffset(0)] 
      public response_status RESPONSE_STATUS; 
      [FieldOffset(0)] 
      public response_version RESPONSE_VERSION; 
      [FieldOffset(320)] 
      public byte[] m_dbname; 
      [FieldOffset(320)] 
      public byte[] m_policyname; 
      [FieldOffset(0)] 
      public request_set REQUEST_SET; 
      [FieldOffset(0)] 
      public response_compare RESPONSE_COMP; 
     } 
     [StructLayout(LayoutKind.Sequential)] 
     public struct comData 
     {  
      public ushort m_type;   
      public byte m_response_result;   
      public dataunion data;  
     }

代碼中沒有'FieldOffset'。請提供一個[MCVE] –

@KyleKhalaf我更新了一些源代碼的問題 – mamur

您可以閱讀更多關於此here。我相信那裏的信息是可以理解的，我不需要在這裏複製它。祝你好運！

我跟着上面的鏈接並編輯了我的代碼，但它仍然給出錯誤 – mamur
