C＃checkBox_CheckedChanged在不同文件中引用

Question

要求：我有一個用C＃編寫的Windows應用程序，我試圖在其中添加一個複選框，如果它被選中，比搜索的文件將複製到基於子目錄的在郵政編碼上。

問題：當我引用來自MainForm.cs addzipdir_checkBox.Equals（真）在不同的頁面SearchProcess.cs我得到的錯誤：「addzipdir_checkBox不會在當前的背景下存在」。什麼是引用checkBox_CheckedChanged發生的正確方法？

這裏有MainForm.cs代碼：

private void addzipdir_checkBox_CheckedChanged(object sender, EventArgs e) 
    { 
     if (addzipdir_checkBox.Equals(true)) 
     { 
      Log("Organize files by zip code."); 
     } 

     if (addzipdir_checkBox.Equals(false)) 
     { 
      Log("Don't Organize files by zip code."); 
     } 
    } 

這裏有SearchProcess.cs產生錯誤代碼：

 if (addzipdir_checkBox.Equals(true)) 
     { 

      // adds the given lead's agentid and zip code to the targetpath string 
      string targetzipdir = m_sc.get_TargetPath() + "\\" + AgentID + "\\" + ZIP; 

      // If the given lead's zip code subdirectory doesn't exist, create it. 
      if (!Directory.Exists(targetzipdir)) 
      { 
       Directory.CreateDirectory(targetzipdir); 
      } 

      targetFileAndPath = m_sc.get_TargetPath() + "\\" + AgentID + "\\" + ZIP + "\\" + fullFileName; 
     } // end if addzipdir_checkBox.Equals(true)

我發現，如果你右擊一個變量，然後單擊「轉到定義」它是一個更容易找到對變量的引用。我右鍵單擊另一個通過MainForm調用的變量，發現它們都是通過SearchCriteria文件調用的。我不得不通過SearchCriteria.cs文件在MainForm.cs文件中引用addzipdir_checkbox值，然後在SearchProcess.cs文件中調用它。

這裏是我的SearchCriteria.cs文件代碼：

public class SearchCriteria 
{ 
    private String Corp; 
    private String OrderNumber; 
    private String Campaign; 
    private String City; 
    private String State; 
    private String Zip; 
    private String SourcePath; 
    private String TargetPath; 
    private bool SearchOR; 
    private bool SearchAND; 
    private bool addzipdirectory_checkBox; 

    public SearchCriteria() 
    { 
    } 

    public SearchCriteria(String Corp, 
          String OrderNumber, 
          String Campaign, 
          String City, 
          String State, 
          String Zip, 
          String SourcePath, 
          String TargetPath, 
          bool SearchOR, 
          bool SearchAND, 
          bool addzipdirectory_checkBox)    
    { 
     this.Corp = Corp; 
     this.OrderNumber = OrderNumber; 
     this.Campaign = Campaign; 
     this.City = City; 
     this.State = State; 
     this.Zip = Zip; 
     this.SourcePath = SourcePath; 
     this.TargetPath = TargetPath; 
     this.SearchOR = SearchOR; 
     this.SearchAND = SearchAND; 
     this.addzipdirectory_checkBox = addzipdirectory_checkBox; 
    } 
    public bool get_addzipdir_checkBox() 
    { 
     return addzipdirectory_checkBox; 
    } 
    public void set_addzipdir_checkBox(bool x) 
    { 
     addzipdirectory_checkBox = x; 
    } 
}    

這裏是我的Searchprocess.cs文件代碼：

  // Copy the file if ANY of the search criteria have been met 
      if (found) 
      { 

       m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"FOUND: Order_No: " + Order_No + 
                     " barcode: " + barcode + 
                     " MailerCode: " + MailerCode + 
                     " AgentID: " + AgentID + 
                     " City: " + City + 
                     " State: " + State + 
                     " ZIP: " + ZIP}); 


       //passes values to TransferFile 
       TransferFile(directory, barcode, AgentID, ZIP); 
      } 
     } // end for that finds each matching record 

    } 

    // find and copy the file to the target directory string ZIP 
    private void TransferFile(string sourceDir, string filename, string AgentID, string ZIP) 
    { 
     string fullFileName = filename + ".pdf"; 
     string fullFileNameAndPath = sourceDir + "\\" + fullFileName; 
     string targetFileAndPath; 

     if (m_sc.get_addzipdir_checkBox()==true) 
     { 

      // adds the given lead's agentid and zip code to the targetpath string 
      string targetzipdir = m_sc.get_TargetPath() + "\\" + AgentID + "\\" + ZIP; 

      // If the given lead's zip code subdirectory doesn't exist, create it. 
      if (!Directory.Exists(targetzipdir)) 
      { 
       Directory.CreateDirectory(targetzipdir); 
      } 

      targetFileAndPath = m_sc.get_TargetPath() + "\\" + AgentID + "\\" + ZIP + "\\" + fullFileName; 
     } // end if addzipdir_checkBox.Equals(true)

• 你需要確保addzipdir_checkBox是公開的。爲此，您需要使用表單編輯器，選擇addzipdir_Checkbox並將屬性網格的「修改器」項目更改爲public或internal。

• 然後，你需要找到一種方式來引用這種形式的情況下，這樣的事情：

  如果（myForm.addzipdir_checkBox.Equals（真））{ ... ... }
