  NameDescription
Protected methodDBDataPermission() Obsolete. Initializes a new instance of a DBDataPermission class.
Protected methodDBDataPermission(DBDataPermission)Initializes a new instance of a DBDataPermission class using an existing DBDataPermission.
Protected methodDBDataPermission(DBDataPermissionAttribute)Initializes a new instance of a DBDataPermission class with the specified DBDataPermissionAttribute.
Protected methodDBDataPermission(PermissionState)Initializes a new instance of a DBDataPermission class with the specified PermissionState value.

  NameDescription
Public methodAddAdds access for the specified connection string to the existing state of the DBDataPermission.
Public methodAssertDeclares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert can create security issues. (Inherited from CodeAccessPermission.)
Protected methodClearRemoves all permissions that were previous added using the Add method.
Public methodCopyCreates and returns an identical copy of the current permission object. (Overrides CodeAccessPermission.Copy().)
Protected methodCreateInstanceCreates a new instance of the DBDataPermission class.
Public methodDemandForces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodDeny Obsolete. Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodEqualsDetermines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodFromXmlReconstructs a security object with a specified state from an XML encoding. (Overrides CodeAccessPermission.FromXml(SecurityElement).)
Public methodGetHashCodeGets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table. (Inherited from CodeAccessPermission.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIntersectReturns a new permission object representing the intersection of the current permission object and the specified permission object. (Overrides CodeAccessPermission.Intersect(IPermission).)
Public methodIsSubsetOfReturns a value indicating whether the current permission object is a subset of the specified permission object. (Overrides CodeAccessPermission.IsSubsetOf(IPermission).)
Public methodIsUnrestrictedReturns a value indicating whether the permission can be represented as unrestricted without any knowledge of the permission semantics.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodPermitOnlyPrevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodToStringCreates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission.)
Public methodToXmlCreates an XML encoding of the security object and its current state. (Overrides CodeAccessPermission.ToXml().)
Public methodUnionReturns a new permission object that is the union of the current and specified permission objects. (Overrides CodeAccessPermission.Union(IPermission).)
