Question

Does anyone know what the refresh rate of the accelerometer in the wiimote is? Is there a way to find out using Visual C#?

Answer 1

Every 5.02 ms (~200Hz) according to this page (which has loads of great info on it, mostly in links to other articles).

Data from with tk.wii object is 8-bit data reported every 5.02 milliseconds on average (with a 4.90 median and 5.86 in one test). The data is represented as a 0.0-1.0 value the tilt of the controller occupying 21% of that range – tilt values for the X-and Y-axis range from 0.396 to 0.608 with sharp accelerations using the entire range.

It may depend not only upon the device's capabilities, but your connection to it.

Answer 2

100 Hz, according to this pdf.
