The source code for the published Reference Source is pushed through a filter that removes objectionable content from the source. Verboten words are one, Microsoft programmers use profanity in their comments. So are the names of devs, Microsoft wants to hide their identity. Such a word or name is substituted by dashes. In this case … Read more
I think that using StringBuilder in F# is perfectly fine – the fact that sb.Append returns the current instance of StringBuilder means that it can be easily used with the fold function. Even though this is still imperative (the object is mutated), it fits reasonably well with the functional style when you do not expose … Read more
Look like it is a multi thread issue. I locked the thread to prevent multi access to the stringBuilder at the same time. public void AddString(string s) { lock(this.LockObject) { StringBuilder.AppendLine(s); } }
Several of the methods on StringBuilder like Append IIRC, return the StringBuilder so you can call more StringBuilder methods. However the way PowerShell works is that it outputs all results (return values in the case of .NET method calls). In this case, cast the result to [void] to ignore the return value e.g.: [void]$sb.Append($c) Note … Read more
The default capacity of StringBuilder is 16 characters (I used .NET Reflector to find out).
As you mention, you should not use StringBuilder instead of a simple string concatenation expression such as a + ” = ” + b. The latter is faster to type, easier to read, and the compiler will use a StringBuilder internally anyway so there is no performance advantage by rewriting it. However StringBuilder is useful … Read more
If you also want to remove lines that only contain whitespace, use resultString = Regex.Replace(subjectString, @”^\s+$[\r\n]*”, string.Empty, RegexOptions.Multiline); ^\s+$ will remove everything from the first blank line to the last (in a contiguous block of empty lines), including lines that only contain tabs or spaces. [\r\n]* will then remove the last CRLF (or just LF … Read more
Would MemoryStream work for you? The interface might not be quite as convenient, but it offers a simple way to append bytes, and when you are done you can get the contents as a byte[] by calling ToArray(). A more StringBuilder-like interface could probably be achieved by making an extension method. Update Extension methods could … Read more
I know the question is old and has been marked as answered, but I thought I’d add this here in case anyone else comes across this as it’s the first hit on Google for StringBuilder.AppendLine() not working. I had the same problem and it turned out to be an Outlook issue. Outlook re-formats text based … Read more
It’s impossible to say, not knowing the size of string1 and string2. With the call to AppendFormat, it will preallocate the buffer just once given the length of the format string and the strings that will be inserted and then concatenate everything and insert it into the buffer. For very large strings, this will be … Read more
