Question

I am communicating with a measurement isntrument and it returns the data in a single string. The output is like:

string result = "-3.546714E-10A,+0.000000E+00,+5.120000E+02\n";

So what I am interested to get in this string is first and second part. First part is Current in Ampere, and second is TimeStamp (measurement time).

I am trying this code but it does not work:

temp = result.Split(',');

tipair = new Results.TIPair();
tipair.Current = float.Parse(temp[0]);
tipair.Time = float.Parse(temp[1]);

Ideally I want it to be -3.546714E-10 for current and 0 for time (time be any positive number).

UPDATE: I tried to do like below but I get very bad numbers (much bigger than they should be!)

temp = result.Split(',');

tipair = new Results.TIPair();
tipair.Current = float.Parse(temp[0].Substring(0, temp[0].Length - 1));
tipair.Time = float.Parse(temp[1]);

Answer 1

You can parse current using Double.Parse() and valid Number Styles:

string result = "-3.546714E-10A,+0.000000E+00,+5.120000E+02\n";
var parts = result.Split(',');

double current = double.Parse(parts[0].Remove(parts[0].Length - 1),
                        NumberStyles.AllowExponent | NumberStyles.Number);
double time = double.Parse(parts[1],
                        NumberStyles.AllowExponent | NumberStyles.Number);

MSDN, NumberStyles Enumeration:

AllowExponent Indicates that the numeric string can be in exponential notation. The AllowExponent flag allows the parsed string
to contain an exponent that begins with the “E” or “e” character and
that is followed by an optional positive or negative sign and an
integer. In other words, it successfully parses strings in the form
nnnExx, nnnE+xx, and nnnE-xx. It does not allow a decimal separator or
sign in the significand or mantissa; to allow these elements in the
string to be parsed, use the AllowDecimalPoint and AllowLeadingSign
flags, or use a composite style that includes these individual flags.
