Sort float numbers List from small to large

December 13, 2021

I want to sort float numbers List from small to large. I tried to use the array.Sort () method but it doesn’t work.
Below is my code.

 List<float> array = new List<float>();
      array.Add(x);
      listBox1.Items.Add(x);

>Solution :

Just Sort():

List<float> array = new List<float>();

array.Add(x);

array.Sort();

When array (quite a strange name for List<float>) is sorted, we can insert x somewhere in the middle of listBox1.Items. Asuming that listBox1.Items contains ordered float items only, we can put

// Here's we have WinForms ListBox
int at = listBox1.Items.Count;

for (int i = 0; i < listBox1.Items.Count; ++i) {
  if (x < (float) (listBox1.Items[i])) {
    at = i;

    break;
  }
}

listBox1.Items.Insert(at, x);
