In C#, there is no 'var' type. 'var' is just a keyword that tells the compiler to 'analyse whatever comes next to find out the type'. This is done during compilation, not runtime. The variables you speak of are actually typed as anonymous types that the compiler automatically generates during compilation.

If all you are doing is enumerating it, there is no need to convert it to a list: var selected = from s in studentCollection select s; foreach (Student s in selected) { s.Show(); } If you do need it as a list, the ToList() method from Linq will convert it to one for you.

C# (engelska: C-sharp, försvenskning: C-kors) är ett objektorienterat programspråk utvecklat av Microsoft som en del av .NET-plattformen. Språkets utveckling leds av Anders Hejlsberg som rekryterats från Borland där han skapat TurboPascal och varit chefsarkitekt för Delphi. Starting with C# 7.0, the is and switch statements support pattern matching. The is keyword supports the following patterns: Type pattern, which tests whether an expression can be converted to a specified type and, if it can be, casts the variable to a variable of that type. using System; namespace MyLinkedList { class Program { static void Main(string[] args) { var node1 = new Node(); node1.Value = 10; var node2 = new Node(); node2.Value = "some text"; var node3 = new Node
