如何将ac＃逗号分隔值字符串转换为列表？

Question

I'm using C# ASP.NET 4 and SQL Server 2008 R2

I'm getting an object scalar from sql server which is a string containing comma separated values of the form:

7, 12, ... 1, 65

I would like to convert this object into a list?

I thought of the direction:

List<int> myList = new List<int>(new int[] (List)mySqlClass.mySqlQueryReturningAnObject("SELECT CLAUSE");

but this is not going to work.

How do I convert this object into a list?

Full answer:

This answer in use is according to the selected answer (before the update)

List<int> myList = new List<int>(mySqlClass.mySqlQueryReturningAnObject("SELECT CLAUSE").ToString().Split(',').Select(x => Convert.ToInt32(x)).ToList());

Answer 1

var intValues = line.Split(',').Select(x => Convert.ToInt32(x)).ToList();

Update

To ensure your code would be able to process strings like 1,2,3,,,4,5,6 you can use overload of String.Split method

var intValues = line.Split(new[] {','}, StringSplitOptions.RemoveEmptyEntries)
                    .Select(x => Convert.ToInt32(x))
                    .ToList();

Answer 2

Use the .Split() method on the string. It will return an array of strings.

string yourResult = "1,2,3,4,5";
string[] resultsArray = yourResult.Split(new[] {','}, StringSplitOptions.RemoveEmptyEntries);

Answer 3

Did you try String.Split ?

You can split your string with a line as simple as this:

var myString="1,2,4,5,6";
var numberList=myString.Split(',');

Answer 4

You can use simple Array.ConvertAll instuction, like this:

string str = "1,2,3,4,5,7,8,9";
int[]resultInArray = Array.ConvertAll( str.Split(','), item => int.Parse(item));

Answer 5

        private void TestParse()
        {
            string commaseparatedstring = "3, 5,6,19";

            int parsedvalue = 0;

            List<int> valuesint =
                commaseparatedstring.Split(',').Select(elem => int.TryParse(elem, out parsedvalue) ? parsedvalue : 0).ToList(); 

        }

Answer 6

You could try assigning the result to a variable.

Then convert it into a string (if its not already one)

Then do a string split on the comma and assigning the results to a list.
