sealed class

This class represents an application's operating environment, which includes details about the operating system, the current user , and other environment variables . This information is provided through static properties and some helper methods .

You can retrieve command-line arguments as a string from CommandLine or as an array of strings using GetCommandLineArgs( ) . Use the GetLogicalDrives( ) method to get an array of strings containing drive names (for example, C:\ ), and use the GetFolderPath( ) method to get the physical location of a special system folder. You can also retrieve environment variables by key name using the GetEnvironmentVariable( ) method and automatically replace environment variables in a string with the ExpandEnvironmentVariables( ) method, as long as they are delimited with the percent sign (%). For example, on a system with the environment variable MAC_ADDR set to 123456789012 , the string MAC_ADDR=%MAC_ADDR% would be converted to MAC_ADDR=123456789012 .
