将视频文件保存在特定文件夹中：Windows Form Application C＃

Question

Hey guys uhm well as you can see i'm having trouble saving a video file because some answers in some threads here doesn't suggest that a video file should be saved in a database because it will only prolong the process, so the point here is that i'm trying to save a video file from a specific folder. im not that used to "savefiledialog" function yet but i'm doing reseaches about it,

i just need to know if it is possible to create the same video file and save it as a new copy with a different name using savefiledialog.

Here's the sample of my form pre

thanks for your response guys if there's one

You can use System.IO.File.Copy to copy file from a source to destination. For example:

var sourceFile=@"d:\video.avi";
var saveFileDialog = new SaveFileDialog();
//You can offer a default name
saveFileDialog.FileName = "video-copy.avi";
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
    System.IO.File.Copy(sourceFile, saveFileDialog.FileName);
}

If destination file exists, you will receive an exception. You can check for file existence using System.IO.File.Exists or you can overwrite the destination file using System.IO.File.Copy(source, destination, true) .
