删除包含许多子文件夹和子文件夹包含更多的文件夹

Question

我想删除一个文件夹（包含文件和子文件夹），它是包含许多文件和许多子文件夹等等的子文件夹。我用谷歌搜索但无法成功。这是我的代码。

private void TemporaryFiles_Load(object sender, EventArgs e)
        {
            bool b = IsAdministrator();
            if (b != true)
            {
                MessageBox.Show("You Should Login as Admininstartor to run this Software at it's fullest.");
            }
            string TargetFolder = @"C:\Users\user\AppData\Local\Temp";
            DeleteFolderAndFile(new DirectoryInfo(TargetFolder));
    }

static public void DeleteFolderFile(DirectoryInfo directoryInfo)
        { 
            try
            {
                foreach (FileInfo file in directoryInfo.GetFiles())
                {
                    try
                    {
                        file.Delete();
                    }
                    catch
                    {
                        //Do Nothing
                    }
                }
                foreach (DirectoryInfo Folder in directoryInfo.GetDirectories())
                {
                    try
                    {
                        Folder.Delete(true);
                    }
                    catch
                    {
                        //Do Nothing
                    }
                }
                foreach (DirectoryInfo subfolder in directoryInfo.GetDirectories())
                {
                    try
                    {
                        DeleteFolderAndFile(subfolder);
                    }
                    catch
                    {
                        //Do Nothing
                    }
                }
            }
            catch
            { 
                //Do Nothing
            }

        }

问题是只有主文件夹未被删除。

您应该使用带有布尔参数 true 的 DirectoryInfo 删除方法来递归删除。在父/目标文件夹上调用一次。

    DirectoryInfo dir = new DirectoryInfo(TargetFolder);

dir.Delete(true);
