You don't. When the method returns, the copy has completed. The time remaining is 0, and the progress is 100%.

Behind the scenes, it uses the native CopyFile[^] function, which doesn't provide any way to see the progress of the copy operation.

then how can i get the progress??
Is there any other way to copy files in c#??

Yes, you can read and write fixed blocks to copy the file, thus allowing you to calculate progress.

Sorry I don't have one; try studying the documentation for reading and writing files, and developing your own sample.

I just told you I don't have any. You could always make the effort to do a bit of searching for yourself.

I just looked at your previous question on the same subject (update progress percentage in c# console[^]), where this was already explained to you. Please do not repost the same question, you are just wasting our time and your own.

You cannot show any progress just because there are no any hooks into File.Copy. If you need to report progress of file copy (but I doubt that), you need your own version of file copy.

I also answered your question before: update progress percentage in c# console[^].

I don't understand how would you fail to understand it. You could ask some follow-up questions if you needed clarification. I'll gladly answer.
