How can I get and set pixel data in XNA?

Question

I have a 2D texture where I want to get the color of the specified pixel. Do something with it and add a new color to another 2D texture.

I will need to do this with all texture pixels. How can i do this.

No pixel shaders, please. It should be in C #
