I think I haven't seen this kind of problems yet when i searched the internet.

is there a way to seperate double and string when they are stored in a single string variable??

for example i have

C#

string blabla = "4.2 Minutes";

what I want to know is that for example. 4.2 will be stored in variable "numbers" and Minutes will be stored in variable "Letters".
is that possible?

What I have tried:

I have tried using Regex.

C#

string cutie = "4.5 Minutes";
Regex re = new Regex(@"([a-zA-Z]+)(\d+)");
Match result = re.Match(cutie);
string letters = result.Value;
string numbers = result.Value;

well something like this, tho it doesn't work.

Can you change the format of the string ? Can you assume the string is always in the same format ? Is using RegX a requirement ? Do you want to change the data into a TimeSpan ?

If want still want to use a regex try the following.

String blabla = "4.2 Minutes";

Regex regex = new Regex(@"^(?<NUMVALUE>\d*.\d*)\s*(?<STRVALUE>[A-Z][a-z]*)$", RegexOptions.Singleline);

Match match = regex.Match(blabla);

if(match.Success)
{
    String numbers = match.Groups["NUMVALUE"].Value;
    String letters = match.Groups["STRVALUE"].Value;

    Console.WriteLine(numbers);
    Console.WriteLine(letters);
}
else
{
    Console.WriteLine("Not matched");
}

Hi,

To your example, above, do this:

C#

private bool is_double(string val)
{
    try
    {
        Convert.ToDouble(val);
        return true;
    }
    catch
    {
        return false;
    }
}

private void separate_word()
{
   string text = "4.2 Minutes";
   string[] arr = text.Split(' ');

   string letter, number;

    foreach(string item in arr)
    {
        if(this.is_double(item))
        {
            number = item;
        }
        else
        {
            letter = item;
        }
    }
}

Solution 1

For this specific format, you don't need regex. Just splitting on the space is sufficient:

C#

string blabla = "4.2 Minutes";
string[] split = blabla.Split(' ');
string letters = split[1];
string numbers = split[0];
