使用C＃将其另存为Windows Form App中

Question

I'm using this code for making save as of image in c#

SaveFileDialog svf = new SaveFileDialog();
        svf.Filter = "JPEG files (*.jpeg)|*.jpeg";
        if (DialogResult.OK == svf.ShowDialog())
        {
            this.imgbox.Image.Save(svf.FileName,ImageFormat.Jpeg);
        }

I need to make save now for image without change name or location ( apply save not save as as the above code ) how i can use this code for save now ?

Assuming WinForms, add a field or property to the appropriate control to hold the full path to the file currently opened, and call it currentFileName or something.

When opening a file, assign the path to the variable. Now when the user hits the Save menu, you can use the already stored path to overwrite the opened file. You can add a Save As menu that pops up the SaveFileDialog , and afterwards assigns the result to the variable again - if not cancelled.

When the user invokes the New or Close menu, make sure to clear the stored path.
