System.Text Namespaces

.NET Framework 4.6 and 4.5

The System.Text namespaces contain types for character encoding and string manipulation. A child namespace enables you to process text using regular expressions.

Namespace Description
System.Text The System.Text namespace contains classes that represent ASCII and 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.
System.Text.RegularExpressions The System.Text.RegularExpressions namespace contains classes that provide access to the .NET Framework regular expression engine. The namespace provides regular expression functionality that may be used from any platform or language that runs within the Microsoft .NET Framework. In addition to the types contained in this namespace, the System.Configuration.RegexStringValidator class enables you to determine whether a particular string conforms to a regular expression pattern.
