Need help converting c # foreach loop to lambda

Question

Is it possible to implement the following loop using IQueryable, IEnumerable, or lambda expressions using linq

private bool functionName(int r, int c)
{
    foreach (S s in sList)
    {
        if (s.L.R == r && s.L.C == c)
        {
            return true;
        }
    }

    return false;
}

if so how?

Answer 1

Try:

private bool functionName(int r, int c)
{
    return sList.Any(s => s.L.R == r && s.L.C == c);
}

Any extension method in Linq is applied to the IEnumerable sequence (which may be an example) and returns true if any of the elements in the sequence returns true for the given predicate (in this case, the lambda function s => s.L.R == r && s.L.C == c).

Answer 2

sort of:

return sList.Any(s => s.L.R == r && s.L.C == c);

Answer 3

(s.L.R??), , , , 100 :

return sList.Any(s => s.L.R == r && s.L.C == c);

/e: , , , . .

Answer 4

private bool functionName(int r,int c)
{
  var ret = from s in sList where s.L.R==r&&s.L.C==c select s;
  return ret.Count()>0;
}
