需要从反斜杠分隔的变量中提取数据

Question

I have a variable that I need to extract data from separated by a back slash. My variable data would be

A\123\FRONT\BACK\49585856

I need to extract the second piece based on the back slashes

Thanks in advance!

I haven't tried anything yet since I am having trouble finding documention

Answer 1

as @rufus said

string x = @"A\123\FRONT\BACK\49585856";

string[] b = x.Split('\\');

Console.WriteLine(b[2]);

Answer 2

The method you need is Split

Split is used to break a delimited string into substrings. You can use either a character array or a string array to specify zero or more delimiting characters or strings. If no delimiting characters are specified, the string is split at white-space characters.

using System;

public class SplitExample
{
    public static void Main(string[] args)
    {
        const char separator = '\\';
        string data = @"A\123\FRONT\BACK\49585856";
        
        string[] myVariables = data.Split(separator);
        
        Console.WriteLine(myVariables[1]); // myVariables[1] = 123
    }
}

Altought if you always need only the second element:

The Split method is not always the best way to break a delimited string into substrings. If you don't want to extract all of the substrings of a delimited string, or if you want to parse a string based on a pattern instead of a set of delimiter characters, consider using regular expressions, or combine one of the search methods that returns the index of a character with the Substring method.
