repeat character   

Hi:
vs2008 c#
Having a string myvar = "*";

I need to repeat this myvar 100 times when is used at run time...

string myline = myvar + myvar+ myvar....(100 times)

What the easiest way to acomplish this.

am trying to avoid the for loop

Well, then,

   myline = 
"****************************************************************************************************";

should do, right? :-)

There's nothing wrong with a for loop, you just need to avoid excessive 
string creation and memory allocation. You can accomplish that with 
StringBuilder:

   StringBuilder b = new StringBuilder(myvar.Length * 100);
   for (int i = 0; i != 100; ++i) {
     b.Append(myvar);
   }
   string myline = b.ToString();

If "myvar" will always be a single character, you can use the 
StringBuilder.Append() override that's especially for this.

Re: repeat character   

is it a string or a char?

For example, one option is:

    string s = new string('*', 100);

if it is genuinely a string (and might be multiple characters), then 
something like:

    static string Repeat(string input, int count)
    {
        StringBuilder sb = new StringBuilder(input.Length * count);
        for (int i = 0; i < count; i++)
        {
            sb.Append(input);
        }
        return sb.ToString();
    }

Re: repeat character   

String myline = String('*', 100);

Lots of useful constructors for String.

RE: repeat character   

Either:
myvar = myvar.PadLeft(100, myvar[0]);
or:
myvar = String('*',100);
***remember to use single quotes on that as it takes a char not a string***

Multiple answers and so far, all can be correct, so I thought I'd throw in 
another case...

If the string or "character" is just a space (which in your example, it 
showed an asterisk [*], but I'm throwing in a space just for show):

string myvar = string.Empty.PadRight(100);

- OR - a normal character (note, char is not string):

string myvar = string.Empty.PadRight(100, '*');

Personally, I would use the constructor for string that takes a character 
and count (already posted by someone else, but duplicated here):

string myvar = new string('*', 100);


There ;)  HTH,

RE: repeat character   

thanks to all...
I like 
string s = new string('*', 100);

the s  will be filled with 100 '*' at run time
 (the char is known only at run time)
