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

Also consider using
还可以考虑使用
Double.TryParse("1.234567E-06", System.Globalization.NumberStyles.Float, out MyFloat);
This will ensure that MyFloatis 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..Catchblock and set MyFloatto a value of your choosing when an exception is detected.
MyFloat如果由于某种原因无法执行转换，这将确保将其设置为值 0。或者您可以将Double.Parse()示例包装在一个Try..Catch块中，并MyFloat在检测到异常时设置为您选择的值。
