How to get image file name inside a folder with jpeg extension and rename it?

There is a folder with an image and every month we change the image in the folder with different names. I need to get the image filename and then rename it to a default image filename to be loaded into a picture box automatically once form runs.
string fileName = Path.GetFileName(#"\\192.168.1.100\pic\a.jpeg");
label1.Text = fileName;
I tried this code but the path contains the image name. What if we change the image inside the folder with different name? It will cause error. I need to get automatically the image name with a specific extension, jpeg for example. And then rename it to a.jpeg. Every image pasted to the folder will have a default name which is a.jpeg.

You can get files with a certain extension using
string[] files = System.IO.Directory.GetFiles(path, "*.jpeg");
and for renaming you can use
System.IO.File.Move("oldfilename", "newfilename");

Find the Directory of folder in root from a aspx page which is inside a folder in asp.net

I have a aspx page to upload image to a folder.The aspx page is inside a folder called admin.
If i keep the aspx page in the root directory i am able to upload file in the Image folder since both are in the root directory.
But when i do the same keeping the aspx page inside a folder,it shows Could not find a part of the path 'C:\Users\...
So how do i provide path such that i am able to upload image in a folder from a page which is also inside a folder.
Here goes my code:
if( fu_subcat.PostedFile.ContentLength>0 )
{
fn =Path.GetFileName(fu_subcat.PostedFile.FileName);
fu_subcat.SaveAs(Server.MapPath("imag/" + fn));
}
EDIT
It is mapping the path as:
Could not find a part of the path 'C:\Users\lenovo\Documents\Visual Studio 2010\WebSites\emarket\Admin\imag
But i have the folder inside emarket as emarket\imag not emarket\Admin\imag

Best to keep the image in a separate content folder, and then reference the image in a relative path, using the tilda e.g ~"content/image"

Using ~ will get you to the virtual root of your application, so Server.MapPath("~/imag/...") should do it.

This happens because when you call that code from
/Admin/page.aspx
Server.MapPath returns a path which is relative to /Admin/ - so the final path would be /Admin/imag/... To set path from the root you should add a / in front of the path.
Must be
fu_subcat.SaveAs(Server.MapPath("/imag/" + fn));
Notice / in front of the string.
Alternatively you can also add a ~ tilde
fu_subcat.SaveAs(Server.MapPath("~/imag/" + fn));
which points to a root of the current ASP.net application. This will be useful if you application is running in a virtual directory and as a part of global application.

Loading PictureBox Image from resource file with path (Part 3)

I understand that this question has been asked (and answered) before. However, none of the solutions are working for me.
Below is a screen capture of all the relevant pieces of the puzzle:
Screen capture http://dinosaur-island.com/PlantPictureBoxScreenCap.jpg
As you can see there are numerous bitmaps of plants loaded as resources into the Images folder. There is a form with a picturebox named "PlantPicture". There is string, which I know has a good path (because I've checked it in the debugger):
PicPath = PicPath+".bmp";
Screen capture http://dinosaur-island.com/PlantDebugger.jpg
I've tried numerous ways of loading, casting, etc., etc.

The path should be something like: "Images\a.bmp". (Note the lack of a leading slash, and the slashes being back slashes.)
And then:
pictureBox1.Image = Image.FromFile(#"Images\a.bmp");
I just tried it to make sure, and it works. This is besides the other answer that you got - to "copy always".

Ok...so first you need to import the image into your project.
1) Select the PictureBox in the Form Design View
2) Open PictureBox Tasks
(it's the little arrow printed to right on the edge of the PictureBox)
3) Click on "Choose image..."
4) Select the second option "Project resource file:"
(this option will create a folder called "Resources" which you can access with Properties.Resources)
5) Click on "Import..." and select your image from your computer
(now a copy of the image will be saved in "Resources" folder created at step 4)
6) Click on "OK"
Now the image is in your project and you can use it with the Properties command. Just type this code when you want to change the picture in the PictureBox:
pictureBox1.Image = Properties.Resources.MyImage;
Note:
MyImage represent the name of the image...
After typing "Properties.Resources.", all imported image files are displayed...

It depends on your file path. For me, the current directory was [project]\bin\Debug, so I had to move to the parent folder twice.
Image image = Image.FromFile(#"..\..\Pictures\"+text+".png");
this.pictureBox1.Image = image;
To find your current directory, you can make a dummy label called label2 and write this:
this.label2.Text = System.IO.Directory.GetCurrentDirectory();

The accepted answer has major drawback!
If you loaded your image that way your PictureBox will lock the image,so if you try to do any future operations on that image,you will get error message image used in another application!
This article show solution in VB
and This is C# implementation
FileStream fs = new System.IO.FileStream(#"Images\a.bmp", FileMode.Open, FileAccess.Read);
pictureBox1.Image = Image.FromStream(fs);
fs.Close();

Setting "Copy to Output Directory" to "Copy always" or "Copy if newer" may help for you.
Your PicPath is a relative path that is converted into an absolute path at some time while loading the image.
Most probably you will see that there are no images on the specified location if you use Path.GetFullPath(PicPath) in Debug.

FileNotFoundException why trying to open an image

I have an image in one of my project folders:
Lets say its in:
~/App_Themes/Default/images/SomeImage.png
I want to load this image into a System.Drawing.Image, how do I do that?
If I try using the FromFile method of the Image class:
Image img = Image.FromFile("~/App_Themes/Default/images/SomeImage.png", true);
I get a FileNotFoundException.
I have read some suggesting to store the image into the Server but that's not an option. Is there any way to load this into the Image?

You seem to be using a relative path instead of a file path to locate the image. Try this:
var path = #"~/App_Themes/Default/images/SomeImage.png";
using (Image img = Image.FromFile(Server.MapPath(path)))
{
do some stuff
}

I had a similar problem. The problem for me was that I accidentally added Image folder inside of App_Code folder. I did not updated the code accordingly and therefore I was getting exception.
As soon I removed the Image folder out of App_Code folder, the problem was resolved.
Of course I could have updated also the path in the code.

How to properly use image resource in WPF application

What is the best way to store static images (like toolbox icons) in a WPF app?
Right now I have Images directory and use them like this:
<dxb:BarButtonItem x:Name="rbSignOut" Content="Sign out" Glyph="Images/Icons/close-16x16.png" LargeGlyph="Images/Icons/close-32x32.png" />
I think it's not the best practice because when I move XAML file in to a subfolder, I need to change all paths. Also, it just does not seems right to store paths in code. So how do I do it properly?

Instead of your path, which is relative to the XAML file:
Glyph="Images/Icons/close-16x16.png"
Use a path which is relevant to the application root (using a leading forward slash)
Glyph="/Images/Icons/close-16x16.png"
No matter where your XAML file is, your image will always be referenced from the root. As long as you don't move your images, you'll always be fine.

Use a ResourceDictionary together with your images. You can add it to the generic.xaml ResourceDictionary so you'll only have to change one path if you move it and you can use the images in every xaml file.

Just Right-Click and change your image's "Build action" to "Content" and use like this
<Image Source="/WPFApplication1;component/Images/Image.png" />
I felt it as the best approach to use Images,Video etc as the Files are not embedded into the assembly.
