Use of var keyword in C#

Answer 1

Many time during testing, I find myself having code like this:

var something = myObject.SomeProperty.SomeOtherThing.CallMethod();
Console.WriteLine(something);

Now, sometimes, I'll want to see what the SomeOtherThing itself contains, SomeOtherThing is not the same type that CallMethod() returns. Since I'm using var though, I just change this:

var something = myObject.SomeProperty.SomeOtherThing.CallMethod();

to this:

var something = myObject.SomeProperty.SomeOtherThing;

Without var, I'd have to keep changing the declared type on the left hand side as well. I know it's minor, but it's extremely convenient.
