繼續如果文件不存在

Question

我有以下代碼：

public static void readtext(string pathtoText) 
{ 

    if (File.Exists(pathtoText)) 
    { 
     string[] lines = System.IO.File.ReadAllLines(pathtoText); 

     // Display the file contents by using a foreach loop. 
     foreach (string line in lines) 
     { 
      clearPath(line); 
     } 
    } 
    else 
    { 
     Console.WriteLine("{0} doesn't exist, or isn't a valid text file", pathtoText); 
    } 
} 

public static void clearPath(string path) 
{ 

    if(Directory.Exists(path)) 
    { 
     int directoryCount = Directory.GetDirectories(path).Length; 

     if(directoryCount > 0) 
     { 
      Console.WriteLine("{0} has Subdirectories to Remove", path); 
      DirectoryInfo di = new DirectoryInfo(path); 

      foreach (DirectoryInfo dir in di.GetDirectories()) 
      { 
       dir.Delete(true); 
      } 
     } 
     else 
     { 
      Console.WriteLine("{0} has no directories to remove", path); 
     } 

     int fileCount = Directory.GetFiles(path).Length; 

     if (fileCount > 0) 
     { 
      Console.WriteLine("{0} has files to Remove", path); 

      System.IO.DirectoryInfo di = new DirectoryInfo(path); 

      foreach (FileInfo file in di.GetFiles()) 
      { 
       try 
       { 
        file.Delete(); 
       } 
       catch(System.IO.IOException) 
       { 
        Console.WriteLine("Please Close the following File {0}", file.Name); 
       } 
      } 
     } 
    } 
    else 
    { 
     Console.WriteLine("Path Doesn't Exist {0}", path); 
    } 
} 

我的功能從文本文件中讀取目錄，並將它傳遞給它的ClearPath檢查，如果目錄存在，如果是這樣，清除它。我的問題是，如果一個目錄不存在，它會停止程序（它不會移動到下一個目錄來檢查它是否存在並且乾淨，每個循環剛剛停止）。

即使特定目錄不存在，我如何才能將它下載到下一個目錄？

您的文件中可能有空行嗎？

你可以嘗試這樣的事情：

foreach (string line in lines) 
{ 
    if (!String.IsNullOrWhiteSpace(line)) 
    { 
     clearPath(line.trim()); 
    } 
}
