c# - How to append another StringBuilder to a StringBuilder

Append another StringBuilder to a StringBuilder
The StringBuilder class represents a mutable String of characters. The StringBuilder class cannot be inherited. The StringBuilder class represents a String-like object whose value is a mutable sequence of characters.

The following .net c# tutorial code demonstrates how we can append another StringBuilder to a StringBuilder instance. That means how we can add another specified StringBuilder object at the end of a StringBuilder instance. In this .net c# tutorial code we will append another StringBuilder object to a StringBuilder instance using the StringBuilder class Append() method.

The StringBuilder Append() method appends the String representation of a specified object to this instance. The StringBuilder Append(StringBuilder) method overload appends the string representation of a specified string builder to this instance.

The StringBuilder Append(System.Text.StringBuilder? value) method overload has a parameter named value. The value parameter is the string builder to append. This method returns a StringBuilder which is a reference to this instance after the append operation is completed.

The Append() method modifies the existing instance of this class. This method does not return a new class instance. Because of this, .net c# developers can call a method or property on the existing reference and they do not have to assign the return value to a StringBuilder object.

So finally, using the StringBuilder class Append(StringBuilder) method overload the .net c# developers can append another StringBuilder to a StringBuilder instance.
