Trying to learn Linq using LinqPad and getting frustated with how to start on it. Let\'s say I want to write a C# Expression and a C# statment where I have a table in SQL server
Check out: http://msdn.microsoft.com/en-us/library/bb397933(v=vs.90).aspx which will give you an introduction to Linq and using lambda expressions.
Then have a look at http://msdn.microsoft.com/en-us/library/bb386927.aspx which will give you the basics, but to answer your specific question:
var products = db.Products.Where(prod => prod.Price > 50);
foreach(var product in products)
{
//do something
}
