Convert from scientific notation string to float in C#

问题

What's the proper way to convert from a scientific notation string such as "1.234567E-06" to a floating point variable using C#?

回答1:

Double.Parse("1.234567E-06", System.Globalization.NumberStyles.Float);

回答2:

Also consider using

Double.TryParse("1.234567E-06", System.Globalization.NumberStyles.Float, out MyFloat);

This will ensure that MyFloat is set to value 0 if, for whatever reason, the conversion could not be performed. Or you could wrap the Double.Parse() example in a Try..Catch block and set MyFloat to a value of your choosing when an exception is detected.
