A String manipulation Question for .NET

Question

How can i remove just first comma + space from below if its there else do nothing.

string comments = ", 38, ";

Answer 1

if( comments.StartsWith(", ") && comments.Length > 2 ) {
  comments = comments.Substring(2);
}

Answer 2

The best way would be to use the String.TrimStart(...) method.

string comments = ", 38, ";
string commentsOK = "38, ";

string trimmedComments = comments.TrimStart(',', ' ');
string trimmedCommentsOK = commentsOK.TrimStart(',', ' ');

After this both trimmedComments and trimmedCommentsOK would have the value "38, ".
