Passing extra argument to string.Format() function in C#
c#
Solution
Looking in Reflector, it will allocate a little more memory for building the string, but there's no massive repercussion for passing in an extra object.
There's also the "side effect" that, if you accidentally included a `{n}` in your format string where `n` was too large, and then added some spare arguments, you'd no longer get an exception but get a string with unexpected items in.
Problem
Is there any side effect of passing and extra argument to `string.Format` function in C#? I was looking at the `string.Format` function documentation at MSDN ( http://msdn.microsoft.com/en-us/library/b1csw23d.aspx) but unable to find an answer. Eg:- ``` string str = string.Format("Hello_{0}", 255, 555); ``` Now, as you can see that according to format string, we are suppose to pass only one argument after it but I have passed two. EDIT: I have tried it on my end and everything looks fine to me. Since I am new to C# and from C background, I just want to make sure that it will not cause any problem in later run.
