Getting a value from ArrayList c#

Question

Hi I'm not to sure how to do this but here's the code that I've got

// splits 1 to 3
int check;
for (int i = 0; i < 100; i++)
{
    check = alM1((rand.next(20))+1);//error
    if (!(alM3.Contains(check)))
        alM3.Add(check);
    if (alM3.Length == 10)
        break;
}
// removes 3 from 1
for (int i = 0; i < 10; i++)
{
    if (alM1.Contains(alM3(i)))  //error
        alM1.Remove(alM3(i));    //error
}

The error message says ArrayList is a variable but it is used like a method. How can I write it so it produces what I want. Thank in advance T

to access array list entries you have to use al[i], not al(i) — x4rf41

check = alM1((rand.next(20))+1);//error - There are too more closing brackets — Vasiliy

To access entries of the list you need to use square bracket notation. For example:

check = alM1[(rand.next(20))+1];

and:

if (alM1.Contains(alM3[i]))
