How can I save Image files in in my project folder?

Question

In my Windows application, I have a PictureBox and a Button control. I want to load an Image file from user from the button's OnClick event and save that image file in a folder name "proImg" which is in my project. Then I want to show that image in the PictureBox.

I have written this code, but it is not working:

OpenFileDialog opFile = new OpenFileDialog();
opFile.Title = "Select a Image";
opFile.Filter = "jpg files (*.jpg)|*.jpg|All files (*.*)|*.*";
if (opFile.ShowDialog() == DialogResult.OK)
{
    try
    {
        string iName = opFile.FileName;
        string filepath = "~/images/" + opFile.FileName;
        File.Copy(iName,Path.Combine("~\\ProImages\\", Path.GetFileName(iName)));
        picProduct.Image = new Bitmap(opFile.OpenFile());
    }
    catch (Exception exp)
    {
        MessageBox.Show("Unable to open file " + exp.Message);
    }
}
else
{
    opFile.Dispose();
}

It's not able to save the image in the "proImg" folder.

Actually the string iName = opFile.FileName; is not giving you the full path. You must use the SafeFileName instead. I assumed that you want your folder on your exe directory also. Please refer to my modifications:

OpenFileDialog opFile = new OpenFileDialog();
opFile.Title = "Select a Image";
opFile.Filter = "jpg files (*.jpg)|*.jpg|All files (*.*)|*.*";

string appPath = Path.GetDirectoryName(Application.ExecutablePath) + @"\ProImages\"; // <---
if (Directory.Exists(appPath) == false)                                              // <---
{                                                                                    // <---
    Directory.CreateDirectory(appPath);                                              // <---
}                                                                                    // <---

if (opFile.ShowDialog() == DialogResult.OK)
{
    try
    {
        string iName = opFile.SafeFileName;   // <---
        string filepath = opFile.FileName;    // <---
        File.Copy(filepath, appPath + iName); // <---
        picProduct.Image = new Bitmap(opFile.OpenFile());
    }
    catch (Exception exp)
    {
        MessageBox.Show("Unable to open file " + exp.Message);
    }
}
else
{
    opFile.Dispose();
}

You should provide a correct destination Path to File.Copy method. "~\ProImages..." is not a correct path. This example will copy selected picture to folder ProImages inside the project's bin folder :

string iName = opFile.FileName;
File.Copy(iName, Path.Combine(@"ProImages\", Path.GetFileName(iName)));

the path is relative to current executable file's location, except you provide full path (i.e. @"D:\ProImages").

In case you didn't create the folder manually and want the program generate ProImages folder if it doesn't exist yet :

string iName = opFile.FileName;
string folder = @"ProImages\";
var path = Path.Combine(folder, Path.GetFileName(iName))
if (!Directory.Exists(folder))
{
    Directory.CreateDirectory(folder);
}
File.Copy(iName, path);

PS: Notice the use of verbatim (@) to automatically escape backslash (\) characters in string. It is common practice to use verbatim when declaring string that represent path.

Solution 3

Try using picturebox.Image.Save function. In my program it is working PictureBox.Image.Save(Your directory, ImageFormat.Jpeg)

example pictureBox2.Image.Save(@"D:/CameraImge/"+foldername+"/"+ numbering + ".jpg", ImageFormat.Jpeg);

Solution 4

You write code like this.

string appPath = Path.GetDirectoryName(Application.ExecutablePath) +foldername ;
pictureBox1.Image.Save(appPath + @"\" + filename + ".jpg", ImageFormat.Jpeg);

still same type of exception .

[har07]

File.Copy assume the folder is already exist. If it isn't you need to create the folder first. Is that the case, ProImages folder hasn't been created yet?

[Saleh Parsa]

After running please check your /bin folder to see the result.

[Amit Kumar]

but images is not in my ProImages folder. it was in bin/ProImages folder .

[Saleh Parsa]

It is going to a PRoImages folder in your /bin/Debug folder aka (executable file directory)

[Amit Kumar]

what if i want to save this path to database, so that later i can use this path to display image.

[Saleh Parsa]

You may create one more string as string dbPath = appPath + iName; and then store dbPath to your database because it will be contains both directory and file name

using System.Drawing.Imaging;

how to do this in separate button? the other button (btnBrowse) loads the image in the picture box, the other button (btnSave) copies the image to the relative folder.
