Question

I have the following string:

string value = "123.456L";

What is the best way to parse this string into a string and a double:

double number = 123.456;
string measure = "L"

Instead of the L, we could also have something else, like oz, m/s, liter, kilograms, etc

Answer 1

Assuming that the units of measure are always expressed as a single character at the back of the string, you can do this:

string value = "123.456L";
var pos = value.LastIndexOfAny("0123456789".ToCharArray());
double number = double.Parse(value.Substring(0, pos+1));
string measure = value.Substring(pos+1);
