Question

我正在尝试删除该文件夹以及该文件夹中的所有文件和文件夹，我正在使用下面的代码并收到错误Folder is not empty，有关我可以做什么的建议吗？

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

尝试：

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

这将以递归方式删除“path”下的所有文件和文件夹，假设您有权这样做。

Answer 4

呃，怎么样只是打电话给Directory.Delete(path, true);？

Answer 5

Directory.Delete方法有一个递归的布尔参数，它应该做你需要的

Answer 6

您应该使用：

dir.Delete(true);

也可以递归删除该文件夹的内容。请参阅MSDN DirectoryInfo.Delete() overloads。

Answer 7

试试这个。

True

Answer 8

对于那些遇到DirectoryNotFoundException的人，请添加以下检查：

if (Directory.Exists(path)) Directory.Delete(path, true);

Answer 9

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);
    }
}

Answer 10

尝试一下：

foreach (string files in Directory.GetFiles(SourcePath))
{
   FileInfo fileInfo = new FileInfo(files);
   fileInfo.Delete(); //delete the files first. 
}
Directory.Delete(SourcePath);// delete the directory as it is empty now.

C＃删除该文件夹以及该文件夹中的所有文件和文件夹
