Int32.TryParse() returns zero on failure - success or failure?

Question

I read this from msdn about Int32.TryParse()

When this method returns, contains the 32-bit signed integer value equivalent to the num

Answer 1

No, TryParse returns true or false to indicate success. The value of the out parameter is used for the parsed value, or 0 on failure. So:

int value;
if (Int32.TryParse(someText, out value))
{
    // Parse successful. value can be any integer
}
else
{
    // Parse failed. value will be 0.
}

So if you pass in "0", it will execute the first block, whereas if you pass in "bad number" it will execute the second block.
