(SFML C#) How do I take a portion of an image, and use it as another sprite...?

[Geoffry_the_Deprogrammer]

I apologise if this is difficult to make sense of, but i am having immense difficulty figuring out how to use spritesheets, as I am currently trying to take a portion of the spritesheet and make that the player sprite, however, i cannot figure out how to set a portion of an image as the sprite... thanks for any and all help...
