Is it possable to make a variable in a function persistant without declairing it outside of the function?

It's amazing to see how much work some people will go through just to avoid a little bit of work.

C# has no equivalent to the "static" keyword applicable
to local variables in a function (but C and C++ do).

I beg to differ, yes the compiler/linker will allocate a function-local static variable outside the function (to keep it alive when the function returns),
but its scope is limited to the function itself, making it inaccessible to
other functions (encapsulation), which is not what you get by declaring
a (static or other) variable outside the function.

string name = "Smith, John";
string lastname = name.Substring(0, name.IndexOf(',')).Trim();
string firstname = name.Substring(name.IndexOf(',') + 1).Trim();
