Constructors

DBDataPermission() DBDataPermission() DBDataPermission() DBDataPermission()

Initializes a new instance of a DBDataPermission class.

DBDataPermission(DBDataPermission) DBDataPermission(DBDataPermission) DBDataPermission(DBDataPermission) DBDataPermission(DBDataPermission)

Initializes a new instance of a DBDataPermission class using an existing DBDataPermission.

DBDataPermission(DBDataPermissionAttribute) DBDataPermission(DBDataPermissionAttribute) DBDataPermission(DBDataPermissionAttribute) DBDataPermission(DBDataPermissionAttribute)

Initializes a new instance of a DBDataPermission class with the specified DBDataPermissionAttribute.

DBDataPermission(PermissionState) DBDataPermission(PermissionState) DBDataPermission(PermissionState) DBDataPermission(PermissionState)

Initializes a new instance of a DBDataPermission class with the specified PermissionState value.

DBDataPermission(PermissionState, Boolean) DBDataPermission(PermissionState, Boolean) DBDataPermission(PermissionState, Boolean) DBDataPermission(PermissionState, Boolean)

Initializes a new instance of a DBDataPermission class with the specified PermissionState value, and a value indicating whether a blank password is allowed.

Properties

AllowBlankPassword AllowBlankPassword AllowBlankPassword AllowBlankPassword

Gets a value indicating whether a blank password is allowed.

Methods

Add(String, String, KeyRestrictionBehavior) Add(String, String, KeyRestrictionBehavior) Add(String, String, KeyRestrictionBehavior) Add(String, String, KeyRestrictionBehavior)

Adds access for the specified connection string to the existing state of the DBDataPermission.

Assert() Assert() Assert() Assert()

Declares 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)
Clear() Clear() Clear() Clear()

Removes all permissions that were previous added using the Add(String, String, KeyRestrictionBehavior) method.

Copy() Copy() Copy() Copy()

Creates and returns an identical copy of the current permission object.

CreateInstance() CreateInstance() CreateInstance() CreateInstance()

Creates a new instance of the DBDataPermission class.

Demand() Demand() Demand() Demand()

Forces 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)
Deny() Deny() Deny() Deny()

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)
Equals(Object) Equals(Object) Equals(Object) Equals(Object)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.

(Inherited from CodeAccessPermission)
FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement)

Reconstructs a security object with a specified state from an XML encoding.

GetHashCode() GetHashCode() GetHashCode() GetHashCode()

Gets 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)
GetType() GetType() GetType() GetType()

Gets the Type of the current instance.

(Inherited from Object)
Intersect(IPermission) Intersect(IPermission) Intersect(IPermission) Intersect(IPermission)

Returns a new permission object representing the intersection of the current permission object and the specified permission object.

IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission)

Returns a value indicating whether the current permission object is a subset of the specified permission object.

IsUnrestricted() IsUnrestricted() IsUnrestricted() IsUnrestricted()

Returns a value indicating whether the permission can be represented as unrestricted without any knowledge of the permission semantics.

MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
PermitOnly() PermitOnly() PermitOnly() PermitOnly()

Prevents 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)
ToString() ToString() ToString() ToString()

Creates and returns a string representation of the current permission object.

(Inherited from CodeAccessPermission)
ToXml() ToXml() ToXml() ToXml()

Creates an XML encoding of the security object and its current state.

Union(IPermission) Union(IPermission) Union(IPermission) Union(IPermission)

Returns a new permission object that is the union of the current and specified permission objects.
