Appending a string

[Paul Roberts]

Hiya

I have a string with about 300+ characters, how can i insert a line break or
another character every 50 characters for the whole string?

I'm using this code, which works if the string is in multiples of 2, but if
not a get an error of OutOfRange, how can i fix this?
int cursor = 0;
string hello = "1234567890 0";

StringBuilder bs = new StringBuilder() ;

while (cursor < hello.Length)
{
bs.Append (hello.Substrin g(cursor, 2));
bs.Append ("HERE");
cursor += 2;
}

Change your while loop to:

while (cursor < hello.Length)
{
int snippetLength = Math.Min(2, hello.Length - cursor);
bs.Append (hello.Substrin g(cursor, snippetLength)) ;
bs.Append ("HERE");
cursor += snippetLength;
}

Note that that still involves a lot of unnecessary copying - all those
Substring calls.

Instead, use bs.Append (hello, cursor, snippetLength);

Did everyone forget that were only talking about 300+ characters. Use the
short method...don't overkill it.

It depends whether "300+" means "over 300" or "just a bit over 300". If
it's the former, it could be huge. I agree it's generally best to go
with the simple solution - worth bearing the more efficient one in mind
in this case though, possibly making a note in a comment in case the
method ends up being a bottleneck.

Yup... String.Concat is equal to StringBuilder up to 7 strings of 25
characters
length. At 13 strings, StringBuilder is twice as efficient as
String.Concat.

I'll be glad too, and hopfully it may help someone else out to :)

int cursor = 0;
StringBuilder sb = new StringBuilder() ;

while (cursor < longstring.Leng th)
{
int size = Math.Min (50, longstring.Leng th - cursor);
sb.Append (longstring, cursor, size);
sb.Append ("\r\n");
cursor += size;
}

Console.WriteLi ne(sb);
