How to round a double value to a selected number of decimals in .NET?

I use an acceleration sensor to calculate the current accelerations and it returns the double value.

However I would like to compare the current acceleration with value 9.8. Before doing that i have to round the value received from the sensor so the question is: How to round a double value to a selected number of decimals in .NET?
