Question

我有一些文件夹，这些文件夹有一些文本文件，我需要删除这些文件，但我的代码出错！

                    var dateFolder = Directory.GetDirectories(@"data\stdate").Select(Path.GetDirectoryName).ToArray();
                    foreach (var dateFile in dateFolder)
                    {
                        var stDates =
                            Directory.GetFiles(@"data\stdate\" + dateFile + "date").Select(Path.GetFileName).ToArray();

                        foreach (var date in stDates)
                        {
                            File.Delete(@"data\stdate\" + dateFile + "date\\" + date);
                        }
                        Directory.Delete(@"data\stdate\" + dateFile + "date");
                    }

Answer 1

    System.IO.DirectoryInfo di = new DirectoryInfo(@"data\stdate");

         //This for delete all file in "data\stdate"
        foreach (FileInfo file in di.GetFiles())
        {
            file.Delete();
        }
        //***************************For delete file in folder

        //This for delete all Subfolder and his files in "data\stdate"
        foreach (DirectoryInfo dir in di.GetDirectories())
        {
            dir.Delete(true);
        }
        //*************************
        //This for delete the parent folder "stdate"
        di.Delete();

Answer 2

试试这个：

Directory.Delete("Path", true); //true: It will delete directory by given path, also folders and files in it.

Answer 3

我删除了原始文件夹，然后再次创建它！

public interface AsyncResponse {

    void onSuccess(Object result);
    void onError();

}

Answer 4

我建议你使用系统环境变量，见这里：

https://en.wikipedia.org/wiki/Environment_variable

原因是，就像您发现的那样：有时可执行文件没有在您编译程序时所期望的目录中运行。

EX：

    String query = "%SystemDrive%";
    str = Environment.ExpandEnvironmentVariables(query);

    Delete(str, true);

这样就保证了可预测的路径而不是相对路径。
