How to print the contents of an array to a label in c# [duplicate]

问题:

This question already has an answer here:

• Convert array of integers to comma-separated string 5 answers

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);

You can do it using Linq:

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