the last (50, 50) (100, 100)

how can prefered c# ?

thanks in advance help

to create texture png file, use texture2d.fromstream() method (msdn).

to draw different sections of texture, use sourcerectangle parameter overload of spritebatch.draw accepts (msdn).

here's example code:

// presumably in update or loadcontent: using(filestream stream = file.openread("uploaded.png")) {     mytexture = texture2d.fromstream(graphicsdevice, stream); }  // in draw: spritebatch.begin(); spritebatch.draw(mytexture, new vector2(111), new rectangle( 0,  0, 50, 50), color.white); spritebatch.draw(mytexture, new vector2(222), new rectangle( 0, 50, 50, 50), color.white); spritebatch.draw(mytexture, new vector2(333), new rectangle(50,  0, 50, 50), color.white); spritebatch.draw(mytexture, new vector2(444), new rectangle(50, 50, 50, 50), color.white); spritebatch.end();
