How to convert this scientific notation to decimal?

Question

After search in google, using below code still can not be compiled:

decimal h = Convert.ToDecimal(\"2.09550901805872E-05\");   

decimal h2 = Decima         


        

Answer 1

Since decimal separator ("." in your string) can vary from culture to culture it's safier to use InvariantCulture. Do not forget to allow this decimal separator (NumberStyles.Float)

  decimal h = Decimal.Parse(
    "2.09550901805872E-05", 
     NumberStyles.Float | NumberStyles.AllowExponent,
     CultureInfo.InvariantCulture);

Perharps, more convenient code is when we use NumberStyles.Any:

  decimal h = Decimal.Parse(
    "2.09550901805872E-05", 
     NumberStyles.Any, 
     CultureInfo.InvariantCulture);
