Image files, model files, sound files, etc. used in the game should be added to the project in advance.


Add a file that will be a resource. Images and models are basically added to the "Content" project. Right-click the Content project and choose Existing Item.


The Add Existing Item dialog opens. Select the files you want to add and click the Add button.

You can see that the file has been added to the project as shown.


If you don't want to add it from the dialog, you can also add it by dragging and dropping from the explorer. However, please note that in Windows Vista and Windows 7, you cannot drag and drop if the permissions of the launched application are different.

Once you've added the file, create a program to read it. When you add a resource to a project, the Content Pipeline uses the . .xnb file, which is perfect for use in games. To read it, use the "ContentManager" class. The ContentManager class is built into the Game class.

To load a resource (content), use the "ContentManager.Load" method. This time, it is read appropriately and is not used for another purpose. Since the class to be created differs depending on the file format to be loaded, a class is created according to the file by specifying "Texture2D" or "SpriteFont" as the type parameter of the Load method. Also, since the parameter passed in the argument is relative to the content project or the folder specified in "ContentManager.RootDirectory", you must specify the file name (without the extension) including the folder name (the asset name to be precise).

Texture2D texture = this.Content.Load<Texture2D>("Texture");
SpriteFont font = this.Content.Load<SpriteFont>("Font");
Model xModel = this.Content.Load<Model>("XModel");

ContentManager.Load method

Reads an asset created by the content pipeline and creates an instance of the class specified in the type parameter. Also, if you specify an asset that has already been created, it returns a reference to an existing instance.

T No limit Specify the type of asset. Classes that can be specified by default include "Model", "SpriteFont", "Effect", "Texture2D", "Texture", and "TextureCube", but you can also specify serializable classes such as "string", "List<T>", and classes that you have created yourself.
assetName string Specify the name of the asset you want to import. Since it is a relative path from the specified root directory, you need to write the path if there is a folder. Also, note that the asset name is not the same as the file name.
Return Values T Returns an instance (T) of the loaded asset. If you've loaded the same asset before, it only returns references to the same instance as before.

The other tips assume that you are loading the content, so please refer to this page if you are unsure.
