The binary + operator performs string concatenation when one or both operands are of type string. If an operand of string concatenation is null, an empty string is substituted. Otherwise, any non-string argument is converted to its string representation by invoking the virtual ToString method inherited from type object.

由此可知 C#的加号运算子预设就支援字串串加的功能，只要一群字串串接的物件中只要有一个以上的物件型别是「字串」的话，就会全部变成「字串相加」，只要遇到「非字串」的物件，预设会使用继承至 object 物件的 ToString 方法进行转型，让所有物件都变成「字串」后进行相加动作。
