It should always be considered that a string cannot be really "expanded", since basically it contains the characters used in the string in the form of an array, and arrays cannot expand. What really happens when concatinating strings is a new string is created which contains the partial strings, and if you for example do it like string a += string b, the old string a will be deleted. So this is a very costly thing in terms of time and memory consuming (even if the memory will be freed afterwards in this case). Same thing with arrays (in visual basic there is the awful "redim" function which also does not resize an existing array but allocates new memory and moves the array content to a new location).
This is crucial when you work with large string constructions like sql statements where a lot of partial strings form the final sql statement.
Better consider using special generic containers in this case which only once produce a string when all parts have been stored in the container.
In C# there is a StringBuilder class for this reason.
This string behaviour is true in each and every programming language.

Itnt din bad video a rhi ha
