将用逗号分隔的数据点字符串转换为List <int> 在C＃中

Question

How to get List<int> value from string value separated by comma like below

string s={ 23,234,0,12,43,6,34,45,7 }

In this case:

      string[] s = data.Split(',');

      List<int32> li = new List<int32>();

        foreach (String sout in s)
        {
            li.Add(Convert.ToInt32(sout));
        }

but getting error like "Input string was not in a correct format." @ "Input string was not in a correct format."

Answer 1

Try this

string s="23,234,0,12,43,6,34,45,7";

string[] s = data.Split(',');

List<int32> li = new List<int32>();
        foreach (String sout in s)
        {
            int i;
            if (Int32.TryParse(sout, out i))
                li.Add(i);
        }

Answer 2

var myString = "23,234,0,12,43,6,34,45,7";
string[] myStrings = myString.Split(',');
var myList = new List<string>();
myList = myStrings.ToList();
var myListInt = new List<int>();
myListInt = myList.Select(s => Convert.ToInt32(s)).ToList();

Or even you can use Regex

var myString = "23,234,0,12,43,6,34,45,7";
var matches = Regex.Matches(myString, @"[^,]+");

You can iterate matches in the foreach statement.

Answer 3

This works like a charm...

var str = "23,234,0,12,43,6,34,45,7";
List<Int32> integers = new List<String>(str.Split(',')).ConvertAll(s => Convert.ToInt32(s));

Pls mark it as answer if it helps..
