how to get all the products that start with J in Linq? ps Simple

Question

Trying to get my head into Linq to Objects and for the life of me it escapes me...I want to get a list of all the products where the _name starts with J.

            Product prod;


            for (int i = 0; i < 10;i++ ) {
                prod = new Product();
                prod._Name = "J" + i.ToString();
                prod._Surname = "F" + i.ToString();


            }

Update

            Product prod;
            List<Product> productList = new List<Product>();


            for (int i = 0; i < 10;i++ ) {
                prod = new Product();
                prod._Name = "J" + i.ToString();
                prod._Surname = "F" + i.ToString();

                productList.Add(prod);
            }

            var query = productList.Where(p=> p._Name.StartsWith("J"));

Thanks Jon

Answer 1

Well you haven't given a collection of any kind in your code sample, but assuming you have a collection called products you want something like:

var query = products.Where(prod => prod._Name.StartsWith("J"));

That will give an IEnumerable<Product>. If you want a List<Product> just add a call to ToList() to the end:

var query = products.Where(prod => prod._Name.StartsWith("J"))
                    .ToList();

If you want to get rid of this error, juste move the Product proc; in your loop :

for (int i = 0; i < 10;i++ ) {
    Product prod = new Product();
    ...
