Question

I would like to know the differences between these two ways of declaring variables.

Type 1

private string procedure_add = "";
private string procedure_update = "";
private string procedure_delete = "";

Type 2

private string procedure_add = "", procedure_update = "", procedure_delete = "";

Does this give the same effect?. Is the memory consumption the same?

Answer 1

There is no any difference. it’s all about the accessibility. the way how the code looks.
suppose if you have 10000+ line of code, while editing you may get stumped by identifying the “,” in declaration .

1. if you have one or two variable, then declare it in a single line
2. writing each declaration in separate line will look code cleaner, and better to debug.

this method which i prefer to use.

private string yourVar = String.Empty;
