Replace image with new image

when i try to delete the image i get this error i tried to dispose of the picture box but that doesn't seem to work.
System.IO.IOException: 'The process cannot access the file
'C:\Users*******\Documents\Visual Studio
2019\Project****************\dbo\DBImages\Bolgheri Sassicaia.jpg'
because it is being used by another process.'
the image i load from this folder, i want to delete it and then add another picture with the same name.
pretty much i want to update the image.
This is where i load the image to the picture box
if (imagepathtext.TextLength > 0)
{
image1 = Image.FromFile(imagepathtext.Text);
drinkImageView.Image = image1;
}
This is where i try to replace the image.
private void UpdatebtnClick(object sender, EventArgs e)
{
if (imagepath.TextLength > 9)
{
DialogResult result = MessageBox.Show("Are you also trying to
update image?", "Confirmation", MessageBoxButtons.YesNo);
if (result == DialogResult.Yes)
{
image1.Dispose();
System.IO.File.Delete(imagepathtext.Text);
}
}
}

You have to dispose image1 object to close file handle. This is actual object keeping handle to your file.
Before this call
System.IO.File.Delete(imagepathtext.Text);
make sure to dispose image1 object
image1.Dispose();

So i figured it out after long trials and error.
We have to dispose of the image before loading the new image.
like so
private void BrowseImage_Click(object sender, EventArgs e)
{
DrinkView.Image.Dispose();
var imagePath = image.BROWSEIMAGE();
if (imagePath.Length > 10)
{
DrinkView.Image = new Bitmap(imagePath);
imagepath.Text = imagePath;
}
}

PictureBox loses its image on navigating to different application

I started developing Windows Forms Applications recently. I'm working with PictureBox and I'm facing an issue with it. It is losing the image as shown in below pictures when I navigate out or if I minimize it and open it back. Any help is greatly appreciated.
private void button1_Click(object sender, EventArgs e) {
try {
using (FileStream fs = new FileStream("C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg", FileMode.Open, FileAccess.Read)) {
using (Image original = Image.FromStream(fs)) {
Bitmap image1 = (Bitmap)original;
pictureBox1.Image = image1;
pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.Refresh();
}
}
}
catch (System.IO.FileNotFoundException) {
MessageBox.Show("There was an error opening the bitmap." +
"Please check the path.");
}
}
Forms Application before Navigating
Forms Application after Navigating to another app or minimizing it

This is because you are disposing the image
using (Image original = ....
{
Bitmap image1 = (Bitmap)original;
// ...
}
image1 is the same object as original, just cast to Bitmap, and gets disposed right after being painted on the screen (with Refresh method).
To fix the problem, use the following instead
Bitmap image1 = new Bitmap(original);
// ...

Previewing images in a listBox using pictureBox

I am using Winforms to create a 2D Map Editor.
I want to be able to preview an image of my assets that are stored in listBox using a pictureBox.
My current code for doing so is thus.
private void listBox_Assets_SelectedIndexChanged(object sender, EventArgs e)
{
pictureBox1.Image = Image.FromFile(((FileInfo)listBox_Assets.SelectedItem).FullName);
}
But when I select an asset I get this error.
Unable to cast object of type 'System.String' to type 'System.IO.FileInfo'.
I have searched high and low for a solution but can't find an answer to this error, any help would be greatly appreciated.

You use the file name from the listbox like this, and protect the code with a check for the file.
private void listBox_Assets_SelectedIndexChanged(object sender, EventArgs e)
{
string file = IO.Path.Combine("the directory", listBox_Assets.SelectedItem);
if (IO.File.Exists(file))
pictureBox1.Image = Image.FromFile(file);
}

How to overlay two images in C#

So ive tried following a load of different tutorials on Stack and the internet on how to do this, but i'm getting nowhere.
this is the closest ive gotten:
private void button1_Click(object sender, EventArgs e)
{
Image image1 = Image.FromFile("S:\\Software\\C#\\Project\\WindowsFormsApplication1\\1.png");
Image image2 = Image.FromFile("S:\\Software\\C#\\Project\\WindowsFormsApplication1\\2.png");
using (Graphics g = Graphics.FromImage(image1))
{
g.DrawImageUnscaled(image2, 0, 0);
}
}
And when i click my button, it executes the code but literally nothing happens, why is this?

You have to do something with your image object afterwards. You have at least two possibilities:
Either save it back to a file using the Image.Save method, e.g.
image1.Save("S:\\Test.jpg");
or place a PictureBox on your Form and put it in there
PictureBox1.Image = image1;
...to place it in a new Window:
Form imgForm = new Form();
imgForm.BackgroundImage = image1;
imgForm.Show();

Setting a picture from my Resources programmatically to a PictureBox

How can I set a picture to a PictureBox in code?
The code below gives me the error:
Cannot implicitly convert Bitmap to
String.
private void ptbLocalidadAdd_MouseEnter(object sender, EventArgs e)
{
ptbLocalidadAdd.ImageLocation = Properties.Resources.addg;
}

If the resource is a bitmap, this should work:
ptbLocalidadAdd.Image = Properties.Resources.addg;
