CodeAccessSecurityAttribute Class

Specifies the base attribute class for code access security.

Namespace: System.Security.Permissions
Assembly: mscorlib (in mscorlib.dll)

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
[AttributeUsageAttribute(AttributeTargets::Assembly|AttributeTargets::Class|AttributeTargets::Struct|AttributeTargets::Constructor|AttributeTargets::Method, AllowMultiple=true, Inherited=false)] 
public ref class CodeAccessSecurityAttribute abstract : public SecurityAttribute
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) */ 
public abstract class CodeAccessSecurityAttribute extends SecurityAttribute
SerializableAttribute

AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) 
public abstract class CodeAccessSecurityAttribute extends SecurityAttribute

This attribute class associates a SecurityAction, for example, Demand, with a custom security attribute.

The types that derive from CodeAccessSecurityAttribute are used to help restrict access to resources or securable operations.

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. Use the corresponding permission class derived from CodeAccessPermission for imperative security.

Notes to Inheritors All permission attributes derived from this class must have only a single constructor that takes a SecurityAction as its only parameter.

The following example shows a permission attribute derived from the CodeAccessSecurityAttribute class.

No code example is currently available or this language may not be supported.
