c# example - stringbuilder append tab
The following asp.net c# example code demonstrate us how can we add/append a Tab (tabulation) inside
a StringBuilder characters programmatically at run time in an asp.net application. In .net framework's
StringBuilder Class represent a mutable string of characters.
StringBuilder.Append(String) overloaded method allow us to append a copy of the specified string to this StringBuilder instance. Append(String) method require to pass a parameter named 'value' which value data type is System.String. This string value is the string to append to StringBuilder object.
StringBuilder.Append() method return the modified StringBuilder object which is a reference to this instance after the append operation has completed.
To insert a Tab (tabulation) inside a String, we can put a '\t' in the specified position of this string. So, if our StringBuilder object has two words 'Sample' and 'Text', and we want to append a Tab between the two words then we can follow this procedure.
First, we append the word 'Sample' to the StringBuilder object as StringBuilder.Append("Sample"). Next, we append a Tab to StringBuilder object as StringBuilder.Append("\t") and at last we need to add/append the word 'Text' to StringBuilder object. Finally, we will get a StringBuilder object which have a Tab between two words.
In the following example code, we also save the StringBuilder object to a text file in web server file system. The bellow images shows the output of this tutorial.
