如何在变量C＃中分隔double和string [英] How to separate double and string in a variable C#

问题描述

我想我在搜索互联网时还没有看到过这种问题。



有没有办法在存储时分离double和string在单个字符串变量??



例如我有

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

string blabla = "4.2 Minutes";

我想知道的是例如。 4.2将存储在变量数字中，分钟将存储在变量字母中。

可能吗？



我尝试过的事情：



我尝试过使用Regex。

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.

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像这样，它不起作用。

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

推荐答案

如果想要仍然想要使用正则表达式，请尝试以下方法。

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）;

匹配匹配= regex.Match（blabla）;

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

Console.WriteLine（数字）;
Console.WriteLine（字母）;
}
其他
{
Console.WriteLine（不匹配）;
}

", 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"); }

举个例子，上面，执行此操作：

Hi,

To your example, above, do this:

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;
        }
    }
}
