Upload a picture to the specified folder and then display it in the Pictruebox control on the form

The code is as follows:

private void Btnupload_click (object sender, EventArgs e)

{

Create a dialog box object

OpenFileDialog ofd = new OpenFileDialog ();

Set a title for a dialog box

Ofd. Title = "Please select the uploaded image";

Set a filtered picture format

Ofd. Filter = "picture format |*.jpg";

Set whether to allow multiple selections

Ofd. MultiSelect = false;

If you click the OK button

if (OFD. ShowDialog () = = System.Windows.Forms.DialogResult.OK)

{

Get the full path to the file (including the suffix after the name)

String FilePath = Ofd. FileName;

Display the file path in a text box

Txtimgurl.text = FilePath;

Find the file name "1.jpg" in front of the "\" Location

int position = Filepath.lastindexof ("\ \");

The file name "1.jpg" is truncated from the full path.

String fileName = Filepath.substring (position+1);

Reads the selected file, returns a stream

using (Stream stream = ofd. OpenFile ())

{

Create a stream to write to the resulting file stream (Note: Create a folder named "Images", if you use a relative path, you must create it in the DEGUG directory of this program

If it's an absolute path, put it there, I'm using a relative path.

using (FileStream fs = new FileStream (@ "./images/" + fileName, FileMode.CreateNew))

{

Copy the resulting file stream into the write stream

Stream. CopyTo (FS);

Writes data from the write stream to a file

Fs. Flush ();

}

Pictruebox Display this picture, at this time this picture has been copied a copy in the images folder, it is equivalent to upload

As far as uploading to other places, you can change your mind, this is just the demo process.

Pbshow.imagelocation = @ "./images/" + fileName;

}

Uploads a picture to the specified folder and then displays it in the Pictruebox control on the form
