how to get values of object list using for loop in c#

Question

I have a list of object type in c#. Now I want to get values of each element using for loop . I have searched a lot on web but I always found only foreach loop method.

Your question is very vague. Please add some source code to illustrate the problem. — Chris Mantle

my question is i have a list (List<point> li=new List<point>(); where point is a class and it has two attributes xcor and ycor ) now i want fetch the values of these attributes using for loop. In java we can use something like li.get(index).getxcor(); but in c# i haven't find any such method — Shoaib Ahmed

You can loop over a list using for like shown below, although using foreach is generally cleaner

for (var i = 0; i < list.Count; i++) {
    var xcor = list[i].xcor;
    var ycor = list[i].ycor;
}

The equivalent foreach loop would look like this:

foreach (var point in list)
{
   var xcor = point.xcor;
   var ycor = point.ycor
}

This is how you would get each object in a list of objects with a for loop

List<object> list = new List<object>();

 for (int i = 0; i < list.Count; i++)
 {
      SomeMethodThatDoesSomethingWithAnObject(list[i]);
 }

this would just iterate over the collection and pass the loop counter to the method. Did you mean to pass list[i] as the argument? I would also use a foreach over a for loop, however this is just preference.

yes I did. Thanks for catching that. I edited my post.
