how to solve system.outofmemoryexception in c#

Question

When we upload a video and click into button to convert video into thumbnail image using this code it generate an error 'System.OutOfMemoryException: Out of memory.'

We are using this code

fpUplaodVideo.SaveAs(Server.MapPath("~/UploadFiles/SiteUserID_" + SiteUserID + "/UploadVideo/" + fpUplaodVideo.FileName));

error will occur on this line

System.Drawing.Image img1 = System.Drawing.Image.FromFile(Server.MapPath("~/UploadFiles/SiteUserID_" + SiteUserID + "/UploadVideo/") + fpUplaodVideo.FileName);

Your conversion to a thumbnail image is a bit simplistic, you cannot load a video by simply opening as if it was an image, you will have to do a bit more effort there. Also, asking for an "ASAP" suggestion seems a bit pushy, AKN has the correct answer which explains why you get the error, for converting the video to a thumbnail, I think you will need to do a bit more work — Icepickle, Feb 21 '17 at 06:58

System.Drawing.Image.FromFile will return OutOfMemoryException for below reason

The file does not have a valid image format.
GDI+ does not support the pixel format of the file.

The MSDN documentation for Image.FromFile says this:

OutOfMemoryException

The file does not have a valid image format.

-or-

GDI+ does not support the pixel format of the file.

Granted, this is a bad and nonsensical use of the OutOfMemoryException, but at least it's documented.

As to why this is thrown, it's quite simple - you're trying to load a video file as an image file. The same docs show that the following formats are supported:

BMP

GIF

JPEG

PNG

TIFF

I assume your "UploadVideo" is none of these. In fact, I'm not sure why you assumed that this would produce a thumbnail image. Try looking for a specific library for that. This might be a good start: Thumbnail video C#
