1. Hello Xna for Windows Phone 7

1.1 create an xna project.

Vs will generate the following project.

 

The XnaHelloPhoneContent project contains the resource files (bitmap file, effect file, sprite file) to be used in the project, and the XnaHelloPhone project contains references to the XnaHelloPhoneContent project, you can directly use these resources in the Code. For example, if you want to load font resources, the Code is as follows:

Font = this. Content. Load <SpriteFont> ("SpriteFont1 ");

The parameter in the Load method is the asset name of the font.

 

 

1.2 modify the code.

SpriteBatch = new SpriteBatch (GraphicsDevice );

Font = this. Content. Load <SpriteFont> ("SpriteFont1 ");

}

Protected override void Draw (GameTime gameTime)
{
GraphicsDevice. Clear (Color. Navy );

// TODO: Add your drawing code here
SpriteBatch. Begin ();
SpriteBatch. DrawString (font, this. text,
TextPosition,
