.NET按照创建时间获取文件夹文件

文件创建时间比较    /// <summary>
    /// 文件创建时间比较
    /// </summary>
    public class FileComparer : IComparer
    {
        int IComparer.Compare(object Obj1, object Obj2)
        {
            FileInfo Fi1 = Obj1 as FileInfo;
            FileInfo Fi2 = Obj2 as FileInfo;
            return Fi1.CreationTime.CompareTo(Fi2.CreationTime);
        }
    }

调用实例

DirectoryInfo DirCollege = new DirectoryInfo(PublicInfo.ZipUploadFilePath);
