Question

我想删除一个文件夹，该文件夹中的所有文件和文件夹，我使用下面的代码，我得到的错误Folder is not empty，什么什么建议我可以？

try 
{ 
    var dir = new DirectoryInfo(@FolderPath); 
    dir.Attributes = dir.Attributes & ~FileAttributes.ReadOnly; 
    dir.Delete(); 
    dataGridView1.Rows.RemoveAt(dataGridView1.SelectedRows[i].Index); 
} 
catch (IOException ex) 
{ 
    MessageBox.Show(ex.Message); 
} 

Answer 1

dir.Delete(true); // true => recursive delete 

Answer 2

阅读手册：

Directory.Delete Method (String, Boolean)

Directory.Delete(folderPath, true); 

Answer 3

的Directory.Delete方法具有递归布尔参数，它应该做的事情，你需要

Answer 4

犯错，那只是请拨打Directory.Delete(path, true);？

Answer 5

尝试：

System.IO.Directory.Delete(path,true) 

这将递归删除所有文件和文件夹下的“路径”假设你有权限这样做。

Answer 6

你应该使用：

dir.Delete(true); 

用于递归删除该文件夹中的内容了。请参阅MSDN DirectoryInfo.Delete() overloads。

Answer 7

public void Empty(System.IO.DirectoryInfo directory) 
{ 
    try 
    { 
     logger.DebugFormat("Empty directory {0}", directory.FullName); 
     foreach (System.IO.FileInfo file in directory.GetFiles()) file.Delete(); 
     foreach (System.IO.DirectoryInfo subDirectory in directory.GetDirectories()) subDirectory.Delete(true); 
    } 
    catch (Exception ex) 
    { 
     ex.Data.Add("directory", Convert.ToString(directory.FullName, CultureInfo.InvariantCulture)); 

     throw new Exception(string.Format(CultureInfo.InvariantCulture,"Method:{0}", ex.TargetSite), ex); 
    } 
}

试试这个。

namespace EraseJunkFiles 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      DirectoryInfo yourRootDir = new DirectoryInfo(@"C:\somedirectory\"); 
      foreach (DirectoryInfo dir in yourRootDir.GetDirectories()) 
        DeleteDirectory(dir.FullName, true); 
     } 
     public static void DeleteDirectory(string directoryName, bool checkDirectiryExist) 
     { 
      if (Directory.Exists(directoryName)) 
       Directory.Delete(directoryName, true); 
      else if (checkDirectiryExist) 
       throw new SystemException("Directory you want to delete is not exist"); 
     } 
    } 
}
