Definition

Namespace:

System.Security.Permissions

Assembly:

System.Security.Permissions.dll

Source:

EnvironmentPermissionAttribute.cs

Caution

Code Access Security is not supported or honored by the runtime.

Allows security actions for EnvironmentPermission to be applied to code using declarative security. This class cannot be inherited.

Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

The scope of the declaration that is allowed depends on the SecurityAction that is used.

The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.

Environment variable names are case-insensitive. Multiple environment variable names are specified by separating the names using PathSeparator.

Constructors

EnvironmentPermissionAttribute(SecurityAction)

Initializes a new instance of the EnvironmentPermissionAttribute class with the specified SecurityAction.

Properties

Action	Gets or sets a security action. (Inherited from SecurityAttribute)
All	Sets full access for the environment variables specified by the string value.
Read	Gets or sets read access for the environment variables specified by the string value.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
Unrestricted	Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared. (Inherited from SecurityAttribute)
Write	Gets or sets write access for the environment variables specified by the string value.

Methods

CreatePermission()	Creates and returns a new EnvironmentPermission.
Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
