Why var is used before linq query

Hi,

This is not necessary.....
The var keyword was introduced in C# 3.0. It is an implicit type and the type is determined by the C# compiler. There is no performance penalty when using var. The C# compiler assigns types to the variable when it assigns the value.

It makes programs shorter and easier to read. In short the var keyword is an implicit way of defining data types. It is an indirect way of defining the variable type. The "var" keyword defines the data type statically (at compile time) and not at runtime.

also some time we use it with LINQ and anonymous types that help us reduce the code (reduce effort to create a new class).

hope this will help you.

var rows = from obj in objCollection
                where obj.Member == condition
                select obj;
