c# - Finding file size to decide on size cutoff for loading? -

-

i writing 32 bit app , 4gb, files process can huge upto 3.5 gb, size should consider before loading file processing?

i mean, c# .net suppose have limited ram framework, should cutoff file (though depends on how memory application takes, arrive @ ballpark figure) ? ( dont have file of magnitude, want handle before memory error)

i suppose, need actual file size file size on disk ? , possible find without opening file?

you can use fileinfo.length property.

but instead consider using stream classes (see *reader classes in system.io), allow read parts of file, analyse , discard. in way don't care size of file @ all.
