list<int> c = new List<int>();

for (int i = 0; i < a.count; i++)
{
    for (int j = 0; j < b.count; j++)
    {
        if (a[i] == b[j])
        {
            c.add(a[i]);

You could use the Intersect method:

var c = a.Intersect(b);

This return all values both in a and b. However, position of the item in the list isn't taken into account.
