资料夹如下,需求为自动删除20天前保存的图片
如下为该方法函数,保留天数可以自定义
public static void CleanFile()
{
string path = $"{SvMaster.DataPath}\\Image";\\文件夹路径
DirectoryInfo dir = new DirectoryInfo(path);
FileSystemInfo[] fsinfos = dir.GetFileSystemInfos();
foreach (FileSystemInfo file in fsinfos)
{
DateTime dt = DateTime.ParseExact(file.ToString(), "yyyy-MM-dd", System.Globalization.CultureInfo.CurrentCulture);\\格式化当天日期
if (dt < DateTime.Now.AddDays(-20))\\判定保存天数
{
string newPath = Path.Combine(path, file.ToString());
Directory.Delete(newPath, true);
}
}
}
调用该方法:CleanFile();
