When I need to print "00000", I can use "0"*5 in python. Is there equivalent in C# without looping?
Based on your example I figure you're going to be using these strings to help zero-pad some numbers. If that's the case, it would be easier to use the String.PadLeft()
method to do your padding. You could be using the similar function in python as well, rjust()
.
e.g.,
var str = "5";
var padded = str.PadLeft(8, '0'); // pad the string to 8 characters, filling in '0's
// padded = "00000005"
Otherwise if you need a repeated sequence of strings, you'd want to use the String.Concat()
method in conjunction with the Enumerable.Repeat()
method. Using the string constructor only allows repetition of a single character.
e.g.,
var chr = '0';
var repeatedChr = new String(chr, 8);
// repeatedChr = "00000000";
var str = "ha";
// var repeatedStr = new String(str, 5); // error, no equivalent
var repeated = String.Concat(Enumerable.Repeat(str, 5));
// repeated = "hahahahaha"
One of the String ctor overloads will do this for you:
string zeros = new String('0', 5);
