print out arrays of strings in label (visual studio wpf, C#)

Question

how do I make wpf label print out arrays of strings by using only one label text. I try to loop the answer by putting foreach. however it only print the last string of the array.

this is the example:

input : h t t p

string word = input_box.Text;
string[] split = word.Split(new char[] { ',', ' ' });
foreach (string s in split)
{
     if (s.Trim() != " ")
        label1.Content = s;
}

output:

can anyone please help me?

use label1.Content += s; instead of label1.Content = s;

but better would be using a StringBuilder

string word = input_box.Text;
string[] split = word.Split(new char[] { ',', ' ' });
StringBuilder sb = new StringBuilder();
foreach (string s in split)
{
     if (s.Trim() != " ")
         sb.Append(s);
}

label1.Content = sb.ToString();

String.Join(String.Empty, word.Split(new char[] { ',', ' ' }).Where(s => s.Trim() != String.Empty)) ?
