c# example - stringbuilder append newline
The following asp.net c# example code demonstrate us how can we add/append new line to a StringBuilder
object programmatically at run time in an asp.net application. .Net framework's StringBuilder Class represent
a mutable string of characters. String Builder Class has no built in property or method to append new line to it.
StringBuilder Class StringBuilder.Append(String) overloaded method allow us to append a copy of the specified string to this instance. So, we can append a string (sequence of characters) to a StringBuilder object programmatically by using this Append() method.
.Net framework's System.Environment.NewLine property allow us to get the new line string defined for this environment. So, we can insert a new line to a StringBuilder object by using this System.Environment.NewLine property. This property return a string containing "\r\n" for non-Unix platforms or a string containing "\n" for Unix platforms. The return string is the new line separator characters for specified platform.
For example, we can append a new line to a StringBuilder object as StringBuilder.Append(System.Environment.NewLine). This property append a environment specified new line string to the StringBuilder object. Finally, we get a StringBuilder object which generate new line on specified position.
In the following example code, we also save the StringBuilder object to a text file on web server file system. The text file clearly shows the generated new line on it.
