To construct a new instance of the specified type There is no other way, short of reflection (this includes using system.activator, to construct a new object of a generic type. Note that if you declared it var a = new { } And var o = new object();, then there is one difference, former is assignable only to another similar anonymous object, while latter being object, it can be assigned to anything. You should use new when you wish an object to remain in existence until you delete it If you do not use new then the object will be destroyed when it goes out of scope.
According to this reference for operator new Global dynamic storage operator functions are special in the standard library All three versions of operator new are declared in the global namespac. In the specific case of throw, throw new() is a shorthand for throw new exception() As you can see, there are quite a few places where it can be used (whenever the type to be created can be inferred) to make code shorter The place where i like it the most is for fields/properties
So what do you call just the new part of it The new keyword does exactly what it says on the tin, it creates a brand new object, irrespective of whether one already exists It creates a new object and stuffs the reference to that object inside the variable it has been given, overwriting any previous value (object) the variable held. String array = new string[10]{} //the line you mentioned above was wrong because you are defining an array of length 10 ([10]), then defining an array of length 0 ({}), and trying to set them to the same array reference (array) in one statement.
