I am using the following code block to extract data from image through OCR:

C#

MODI.Document tifDoc = new Document();
                            tifDoc.Create(Server.MapPath("~/Upload/") + fname.Split('.')[0] + ".tif");
                            tifDoc.OCR(MiLANGUAGES.miLANG_SYSDEFAULT, false, false);
                            tifDoc.Save();
                            MODI.Image tifImg = (MODI.Image)tifDoc.Images[0];
                            content += tifImg.Layout.Text;
                            tifDoc.Close(false);
                            tifDoc = null;
                            tifImg = null;
                            GC.Collect();
                            GC.WaitForPendingFinalizers();

But when i try to delete the tiff image, it throws an exception that The process cannot access the file because it is being used by another process . What do I do?

The code does not make sence to me in regards to the question you pose. Why save the file if you want to delete it? Could you elaborate?

I want to delete the file because i dont to store it on my server. I just want to keep the extracted text.

use Using keyword to dispose MODI.Document. if Document class inherits IDisposable.

Member 8491154 13-Aug-12 0:29am

can you please elaborate on your code?

http://msdn.microsoft.com/en-us/library/yh598w02%28v=vs.80%29.aspx please check this MSDN article for how you can dispose your object with using keyword.

MODI.Document class doesn't inherit IDisposable.

check if tifDoc.Flush() or tifDoc.Dispose() exit. if so then use try..catch..finally block and add dispose code in finally block.

These methods don't exists. Only Close(bool) method exists. But it is not allowing the files to be deleted.

There is no method as dispose for MODI.Document

I mean that which instance was created to use you have to dispose or destroy that items other wise you are unable to remove or delete because system is using that item.

Member 8491154 17-Aug-12 8:53am

I know this. I have destroyed it by setting null in its value. But, still it is not destroyed.
