<summary>Controls access to system and user environment variables. This class cannot be inherited.</summary>
<remarks>
<format type="text/markdown"><]
Environment variable names are designated by one or more case-insensitive name lists separated by semicolons, with separate lists for read and write access to the named variables. Write access includes the ability to create and delete environment variables as well as to change existing values.
> [!NOTE]
> In versions of .NET Framework before .NET Framework 4, you could use the <xref:System.Security.CodeAccessPermission.Deny%2A?displayProperty=nameWithType> method to prevent inadvertent access to system resources by trusted code. <xref:System.Security.CodeAccessPermission.Deny%2A> is now obsolete, and access to resources is now determined solely by the granted permission set for an assembly. To limit access to files, you must run partially trusted code in a sandbox and assign it permissions only to resources that the code is allowed to access. For information about running an application in a sandbox, see [How to: Run Partially Trusted Code in a Sandbox](/dotnet/framework/misc/how-to-run-partially-trusted-code-in-a-sandbox).

## Remarks
Use this method to get the state of the current permission. To get both `Read` and `Write` access states requires two calls to this method.
> [!NOTE]
> The `flag` parameter is limited to the values of <xref:System.Security.Permissions.EnvironmentPermissionAccess>, which represent single types of environment variable access. Those values are <xref:System.Security.Permissions.EnvironmentPermissionAccess.Read> and <xref:System.Security.Permissions.EnvironmentPermissionAccess.Write>. The values acceptable to `flag` do not include <xref:System.Security.Permissions.EnvironmentPermissionAccess.NoAccess> and <xref:System.Security.Permissions.EnvironmentPermissionAccess.AllAccess>, which do not represent single types of environment variable access.
