Convert array of integers to comma-separated string (5 answers)

Closed 5 years ago.

I want to display the contents of the Array from a label with a comma between each number. num1 - num6 are integer variables converted from textboxes. So Far I have done this.

int[] number = new int [6] {num1, num2, num3, num4, num5, num6};

Array.Sort(number);

lblAnswer3.Text = number.ToString();

The output of this code is: System.Int32[]

I would like the output to be: num1, num2, num3, num4, num5, num6 in ascending order.

回答1:

You can easily concat IEnumerables and arrays with string.Join:

lblAnswer3.Text = string.Join(", ", number);

回答2:

You can do it using Linq:

lblAnswer3.Text = number.OrderBy(x => x).Select(x => x.ToString()).Aggregate((a, b) => a + ", " + b);
