Anonymous and Named types ASP.Net

Anonymous

In general anonymous types of declared with var keyword like

var a =10;

var b=20.5;

var c=” sai”;

What we use the data type in C# like int, string, double, etc. are known as “named types”.

Anonymous types are introduced in 2.0 versions of .net framework and C#.

Anonymous types cannot be used as Global variables.

Initialize the data into an anonymous type is mandatory.
