Creating a bitmap in C#

Does anyone have some examples or links to something that would point me in the direction of creating .bmps from a console app? All we're trying to do is create a bitmap with a string that the user gives. Seems like this should be easy enough, just need something to look at since I'm new to all this :)

Code:

---

using System;
using System.Drawing;
using System.Drawing.Imaging;

Bitmap bm = new Bitmap(300, 100, PixelFormat.Format24bppRgb);
Graphics g = Graphics.FromImage(bm);
// do drawing to the bitmap

bm.Save("img.bmp");
