Решение

Даценд, благодарю, помогли.

Появился еще один вопросик мелкий, решил не создавать тему.
У меня есть формы FormLevel1 и Helper.
При создании формы FormLevel1 в событии shown() форма Helper вызывается как ShowDialog.

Нужно передавать в label1 формы Helper определенный текст из формы FormLevel1.
Как это сделать?
По простому, как из одной формы, изменить текст label’а другой формы?

Resources, where to put them, and how to reference them in C#

I’ve worked with C# and other programming languages for a while now, and am ashamed to say I’m unfamiliar with the standard on where to put resources such as program icons, and how to reference them within my code.

Specifically, for a C# Windows Forms Application, where would it be appropriate to put my icon resources, and what is the path for referencing them once I get them in the correct place?

Thanks very much for any assistance.

You can add a Resources.resx file to your project and add resources like images, strings, files to it. Then you can reference these resources through an automatically-generated Resources class. By default, Visual Studio will create a Resources.resx file in the Properties directory. Any resources you add to the resources file will be added to the Resources directory by default.

For completion I wanted to expound on some of the answers listed.

Embed in Resources.resx

Resources.resx should have been created when your WinForms project was created. You can view it under Properties in the Solution Explorer .

Double click Resources.resx to open the designer. You can copy from Windows Explorer and paste in the VS resources designer. This tool is smart enough to figure out what type of resource it is, and you can see in the screen shot below that similar resource types are grouped together under the menu bar’s drop down list.

From this point you can follow the accepted answer and manually assign the resource to a control’s property.

Embed in form via designer

Using the designer, you can embed a resource in a form’s .resx . Select the control in the designer and open the Properties window ( F4 is default shortcut key). Find the appropraite property, such as Icon for a form. Click the ellipses button to bring up the Open File dialog. Browse to the resource (if you embedded it in the Resources.resx it will actually be in the Resources folder — which would have been created when you added your first resource to Resources.resx — and you should use the first method above), and select the correct resource.

In the image below you can see the «scrape.ico» file being set as the Main form’s Icon .

This example would end up generating a line in the Main form’s designer like this.

Storing WPF Image Resources

For a WPF application which will need 10 — 20 small icons and images for illustrative purposes, is storing these in the assembly as embedded resources the right way to go?

If so, how do I specify in XAML that an Image control should load the image from an embedded resource?

If you will use the image in multiple places, then it’s worth loading the image data only once into memory and then sharing it between all Image elements.

To do this, create a BitmapSource as a resource somewhere:

Then, in your code, use something like:

In my case, I found that I had to set the Image.png file to have a build action of Resource rather than just Content . This causes the image to be carried within your compiled assembly.

I found to be the best practice of using images, videos, etc. is:

• Change your files «Build action» to «Content». Be sure to check Copy to build directory.
  • Found on the «Right-Click» menu at the Solution Explorer window.
• Image Source in the following format:
  • «/«YourAssemblyName»;component/«YourPath»/«YourImage.png»«

Example

• Files are not embedded into the assembly.
  • The Resource Manager will raise some memory overflow problems with too many resources (at build time).
• Can be called between assemblies.

Load image from resources area of project in C#

I have an image in my project stored at Resources/myimage.jpg. How can I dynamically load this image into Bitmap object?

Are you using Windows Forms? If you’ve added the image using the Properties/Resources UI, you get access to the image from generated code, so you can simply do this:

You can get a reference to the image the following way:

If you want to make a copy of the image, you’ll need to do the following:

Don’t forget to dispose of bmp when you’re done with it. If you don’t know the name of the resource image at compile-time, you can use a resource manager:

The benefit of the ResourceManager is that you can use it where Resources.myImage would normally be out of scope, or where you want to dynamically access resources. Additionally, this works for sounds, config files, etc.

You need to load it from resource stream.

If you want to know all resource names in your assembly, go with:

Way easier than most all of the proposed answers

The best thing is to add them as Image Resources in the Resources settings in the Project. Then you can get the image directly by doing Resources.myimage. This will get the image via a generated C# property.

If you just set the image as Embedded Resource you can get it with:

Where MyTypeFromSameAssemblyAsResource is any type that you have in your assembly.

Code I use in several of my projects. It assumes that you store images in resource only as bitmaps not icons

Use below one. I have tested this with Windows form’s Grid view cell.

Name of «Resource_Image», you can find from the project.

Under the project’s name, you can find Properties . Expand it. There you can see Resources.resx file. Open it. Apply your file name as «Resource_Image».

With and ImageBox named «ImagePreview FormStrings.MyImageNames contains a regular get/set string cast method, which are linked to a scrollbox type list. The images have the same names as the linked names on the list, except for the .bmp endings. All bitmaps are dragged into the resources.resx

In my case — I was using Icons in my resource, but I needed to add them dynamically as Images to some ToolStripMenuItem (s). So in the method that I created (which is where the code snippet below comes from), I had to convert the icon resources to bitmaps before I could return them for addition to my MenuItem .

Something else to be aware of, if your image/icon has spaces (» «) in its name when you add them to your resource, VS will automatically replace those spaces with «_»(s). Because, spaces are not a valid character when naming your resource. Which is why I’m using the Replace() method in my referenced code. You can likely just ignore that line.

Using Image.FromStream is better because you don’t need to know the format of the image (bmp, png, . ).

JDS’s answer worked best. C# example loading image:

• Include the image as Resource (Project tree->Resources, right click to add the desirable file ImageName.png)
• Embedded Resource (Project tree->Resources->ImageName.png, right click select properties)
• .png file format (.bmp .jpg should also be OK)

Note the followings:

• The resource image file is «ImageName.png», file extension should be omitted.
• ProjectName may perhaps be more adequately understood as «Assembly name», which is to be the respective text entry on the Project->Properties page.

The example code line is run successfully using VisualStudio 2015 Community.

С помощью PictureBox элемента управления Windows Forms можно загружать и отображать изображение в форме во время разработки, присвоив Image свойству допустимое изображение. With the Windows Forms PictureBox control, you can load and display a picture on a form at design time by setting the Image property to a valid picture. В следующей таблице приведены допустимые типы файлов. The following table shows the acceptable file types.

Тип Type	Расширение имени файла File name extension
Bitmap Bitmap	BMP .bmp
Значок Icon	ICO .ico
GIF GIF	.gif .gif
Метафайл Metafile	. WMF .wmf
JPEG JPEG	.jpg .jpg
