The only thing comparable in C # is using , which imports the namespaces defined in the assemblies referenced by the project. You cannot βincludeβ a file in the sense that you are deleting content directly in your code.
For example, if your project references the System.Xml assembly, the following code will allow you to access all the classes in this namespace without fully defining their names:
using System.Xml;
This will allow you to use the System.Xml.XmlDocument type, for example, specifying it as an XmlDocument instead of its fully System.Xml.XmlDocument type name System.Xml.XmlDocument .
