How can I replace comma instead of some phrases?-CodePudding

I have a string of characters that starts with a space and has \r\n,I want to delete the first space and delete \r\n then replace it with a comma after the word if there is a space?

My String : "\r\n ram\r\ncomputer\r\n" ....

I want the following mode to change? laptop,computer,ram

CodePudding user response：

As per @valuator answer you can use Trim() to remove trailing spaces. And to address other concerns pointed out in comments, you can use regex replace as below.

string myString = " laptop  computer ram";
var rx= new Regex(@"[\s] ");
myString= rx.Replace(myString.Trim(), ",");

the regex [\s] will match any whitespace characters

Use Trim() to remove the space at the beginning (and/or end) and then Replace() to replace the space between words with commas.
