从科学记数法字符串转换为C＃中的float

Question

使用C＃将科学记数法字符串（如“1.234567E-06”）转换为浮点变量的正确方法是什么？

Answer 1

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

Answer 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.
