 >  This type implements the <xref:System.IDisposable> interface. When you have finished using any type that derives from this type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its <xref:System.IO.TextWriter.Dispose%2A> method in a `try`/`catch` block. To dispose of it indirectly, use a language construct such as `using` (in C#) or `Using` (in Visual Basic). For more information, see Dispose and the "Using an Object that Implements IDisposable" section in the <xref:System.IDisposable> interface topic.

 ## Examples  
- The <xref:System.IO.TextWriter> class is an abstract class. Therefore, you do not instantiate it in your code. The <xref:System.IO.StreamWriter> class derives from <xref:System.IO.TextWriter> and provides implementations of the members for writing to a stream. The following example shows how to write two lines that consist of string values to a text file by using the <xref:System.IO.StreamWriter.WriteLineAsync%28System.String%29> method.
