如何用非数字分隔符分割字符串？

Question

I want to split a string in C# . It should split on the basis of a text in the string.Like i have a string "41sugar1100" , i want to split on the base of text in it that is "sugar" .How can i do this ?

NOTE: Without passing "sugar" directly as a delimiter .Because text can be change in next iteration.Means wherever it finds text in the string, it should split on the basis of that text.

Answer 1

Use Regex.Split :

string input = "44sugar1100";
string pattern = "[a-zA-Z]+";            // Split on any group of letters

string[] substrings = Regex.Split(input, pattern);
foreach (string match in substrings)
{
    Console.WriteLine("'{0}'", match);
}

Answer 2

char[] array = "41sugar1100".ToCharArray();
StringBuilder sb = new StringBuilder();

// Append letters and special char '#' when original char is a number to split later
foreach (char c in array)
    sb.Append(Char.IsNumber(c) ? c : '#');

// Split on special char '#' and remove empty string items
string[] items = sb.ToString().Split('#').Where(s => s != string.Empty).ToArray();

foreach (string item in items)
    Console.WriteLine(item);

// Output:  
// 41  
// 1100

****Use char[] array for split a string from string****

 string s = "44sugar1100";
        char[] c = new char[] { 's', 'u', 'g', 'a', 'r' };
        string[] s1 = s.Split(c,StringSplitOptions.RemoveEmptyEntries);
        string s2 = s1.ToString();

Answer 4

Regex regex = new Regex(@"(?<firstNumber>\d+)(?<word>[^\d]+)+(?<secondNumber>\d+)", RegexOptions.CultureInvariant);

string s = "41sugar1100";
Match match = regex.Match(s);

        if (match.Success)
        {
            string firstNumber = match.Groups["firstNumber"].Value;
            string word = match.Groups["word"].Value;
            string secondNumber = match.Groups["secondNumber"].Value;
        }

Answer 5

I would take the string and put it into a char array then int.tryparse each char in the array for example...

string myString = "44sugar1100";
int num=0; //for storage
string newString="";//for rebuilding
foreach(char ch in myString)
{
    if(int.TryParse(ch, out num)
    {
    newString+=num.toString();
    }
}

Answer 6

string text = "41sugar1100";
string[] array = text.Split('sugar');
