Question

For example:

            for (i = 0; i < 100; i++)
            {
               string myvar = "";
                // Some logic
            }

Do it make performace or memory leak?

Why i do this, because i don’t want “myvar” accessible outside the for..loop.

It is any performance monitor, i can compare the execute time between two snippet or whole program ?

thanks you.

No, variables are purely for the programmer’s convenience. It doesn’t matter where you declare them. See my answer to this duplicate question for more details.
