How to Find the Greatest and lowest value in listbox

问题

I am new in c#,

I am using these to find the greatest and lowest value .

        int[] numbers = new[] { 1,2,3,4,5 };
        int min = numbers.Min();
        int max = numbers.Max();

I want to find the greatest and lowest value from list box by something like this

        int[] numbers = new[] { listbox1.items };
        int min = numbers.Min();
        int max = numbers.Max();

There would be great appreciation if someone could help me.

Thanks In Advance.

try this:

var numbers = listBox1.Items.Cast<object>().Select(obj => Convert.ToInt32(obj));
int min = numbers.Min();
int max = numbers.Max();
