System.Text Namespace

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

The System.Text namespace contains classes that represent Unicode character encodings; abstract base classes for converting blocks of characters to and from blocks of bytes; and a helper class that manipulates and formats String objects without creating intermediate instances of String.

The encoding classes are primarily intended to convert between different encodings or code pages and a Unicode encoding. Encoding::Unicode (UTF-16) encoding is used internally by the .NET Framework, and Encoding::UTF8 encoding is often used for storing character data to ensure portability across machines and cultures.

The StringBuilder class is designed for operations that perform extensive manipulations on a single string. Unlike the String class, the StringBuilder class is mutable and provides better performance when concatenating or deleting strings.

For more information about System.Text, see [bf6d9823-4c2d-48af-b280-919c5af66ae9] and the MSDN blog Shawn Steele's Thoughts about Windows and .NET Framework Globalization APIs.
