C # get file basic information

Scenario Description:

You need to get the file information for the specified path and then manipulate the file

First, obtain the file information, form a DataTable information.

    /// <summary>    ///gets the file information in the specified directory/// </summary>    /// <param name= "path" >Absolute Path</param>    /// <returns></returns>     PublicDataTable GetInfo (stringpath) {        stringFileName ="", FileType ="", capacity ="", EditTime ="", dir ="", File =""; DataTable DT=NewDataTable (); Dt. Columns.Add ("FileName"); Dt. Columns.Add ("FileType"); Dt. Columns.Add ("capacity"); Dt. Columns.Add ("EditTime"); Dt. Columns.Add ("dir"); Dt. Columns.Add ("file"); DirectoryInfo di=NewDirectoryInfo (path); foreach(FileSystemInfo FSIinchdi. Getfilesysteminfos ()) {DataRow Nrow=dt.            NewRow (); if(FSI isFileInfo)//if the file{FileInfo fi=(FileInfo) FSI; FileName= fi. Name;//Get file nameFile = fi. FullName;//get the full catalog                if(FI. Extension.length <1)//if the extension is less than one{FileType=""; }                Else{FileType= fi. Extension.remove (0,1);//get file name extension} dir=fi.                Directory.tostring (); Capacity= Pub. Filecountsize (Convert.ToInt32 (FI. Length.tostring ()));//Calculate File SizeEditTime = fi. Lastwritetime.tostring ();//gets the last modified time            }            Else  //if it is a folder{di=(DirectoryInfo) FSI; FileName=di.                Name; Dir=di.                FullName; File=""; FileType="folder"; Capacity=""; EditTime=di.            Lastwritetime.tostring (); } nrow["FileName"] =FileName; nrow["FileType"] =FileType; nrow["capacity"] =capacity; nrow["EditTime"] =EditTime; nrow["dir"] =dir; nrow["file"] =file; Dt.        Rows.Add (Nrow); } dt. Defaultview.sort="edittime desc"; returnDT; }

Second, call the GetInfo method, display the file information, the result is as follows
