C＃中要数组的整数列表

Question

I have a list of ints called MyList . In javascript, when we call toString on an array of numbers, it converts it into a string with each number separated with commas; I'm looking to do the same with in C#.

I tried calling .ToString () to the list but it's returning the type of the list. I'm thinking of a loop that iterates over the list and add each element to a stringbuilder, along with the comma, and then .ToString() the stringbuilder.

Is that the best way to do it?

Thanks.

Answer 1

使用string.Join ：

string result = string.Join(",", MyList);

Answer 2

You can use the String.Join method to "implode" the array with a separator.

eg:

String.Join(",", MyList);

Answer 3

try use this code :

 List<int> MyList = new List<int>();
            MyList.Add(1);
            MyList.Add(2);
            MyList.Add(3);
            MyList.Add(4);
            MyList.Add(5);
            MyList.Add(6);

            var m = string.Join(",", MyList);

            MessageBox.Show(m.ToString());
