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

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();
