c# 删除文件与删除文件夹

比如要删除指定的文件名时，如下代码

/// <summary>
/// 删除文件夹以及文件
/// </summary>
/// <param name="directoryPath"> 文件夹路径 </param>
/// <param name="fileName"> 指定的文件名称 </param>
public static void DeleteDirectory(string directoryPath, string fileName)
{

    //删除文件
    for (int i = 0; i < Directory.GetFiles(directoryPath).ToList().Count; i++)
    {
        if (Directory.GetFiles(directoryPath)[i] == fileName)
        {
            File.Delete(fileName);
        }
    }

    //删除文件夹
    for (int i = 0; i < Directory.GetDirectories(directoryPath).ToList().Count; i++)
    {
        if (Directory.GetDirectories(directoryPath)[i] == fileName)
        {
            Directory.Delete(fileName, true);
        }
    }
}

调用方法： DeleteDirectory(@"D:\copyfile\zip", @"D:\copyfile\zip\20180916115334");

或者需要直接删除文件夹

Directory.GetDirectories(pathFile).ToList()
  .ForEach(a => Directory.Delete(a,true));
