String question

[ma]

Hello,
I want to create a string with the exact size of say X that each char be
'.'. How can I do this? I tried the following and it did not work:

int x=10;
string tmp="";
tmp.padright(x,'.');

Regards

Strings are immutable, meaning, once you have an instance of it, you
can't change the contents (you actually can, but you have to bend over
backwards to do it).

Rather, all the methods on the string class which appear to modify it
actually return a new instance, so you would do this:

int x = 10;
string tmp = "";
tmp = tmp.PadRight(x, '.');

Of course, in this instance, it would be easier to construct the string
with the characters from the get-go:

int x = 10;
string tmp = new string('.', 10);

string is immutable, so the new value is always the /result/ of the
call - i.e.
string padded = tmp.PadRight('.',x);

Alternatively, if you know the original string is empty:
string padded = new string('.',x);

Hi,

One of the constructors do just that:

string s = new String( '.', 10);
