SecurityIdentifier Class
Visual Studio 2010
Represents a security identifier (SID) and provides marshaling and comparison operations for SIDs.

Assembly: mscorlib (in mscorlib.dll)
The SecurityIdentifier type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | SecurityIdentifier(IntPtr) | Initializes a new instance of the SecurityIdentifier class by using an integer that represents the binary form of a security identifier (SID). |
![]() | SecurityIdentifier(String) | Initializes a new instance of the SecurityIdentifier class by using the specified security identifier (SID) in Security Descriptor Definition Language (SDDL) format. |
![]() | SecurityIdentifier(Byte[], Int32) | Initializes a new instance of the SecurityIdentifier class by using a specified binary representation of a security identifier (SID). |
![]() | SecurityIdentifier(WellKnownSidType, SecurityIdentifier) | Initializes a new instance of the SecurityIdentifier class by using the specified well known security identifier (SID) type and domain SID. |
| Name | Description | |
|---|---|---|
![]() | AccountDomainSid | Returns the account domain security identifier (SID) portion from the SID represented by the SecurityIdentifier object if the SID represents a Windows account SID. If the SID does not represent a Windows account SID, this property returns ArgumentNullException. |
![]() | BinaryLength | Returns the length, in bytes, of the security identifier (SID) represented by the SecurityIdentifier object. |
![]() | Value | Returns an uppercase Security Descriptor Definition Language (SDDL) string for the security identifier (SID) represented by this SecurityIdentifier object. (Overrides IdentityReference.Value.) |
| Name | Description | |
|---|---|---|
![]() | CompareTo | Compares the current SecurityIdentifier object with the specified SecurityIdentifier object. |
![]() | Equals(Object) | Returns a value that indicates whether this SecurityIdentifier object is equal to a specified object. (Overrides IdentityReference.Equals(Object).) |
![]() | Equals(SecurityIdentifier) | Indicates whether the specified SecurityIdentifier object is equal to the current SecurityIdentifier object. |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetBinaryForm | Copies the binary representation of the specified security identifier (SID) represented by the SecurityIdentifier class to a byte array. |
![]() | GetHashCode | Serves as a hash function for the current SecurityIdentifier object. The GetHashCode method is suitable for hashing algorithms and data structures like a hash table. (Overrides IdentityReference.GetHashCode().) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IsAccountSid | Returns a value that indicates whether the security identifier (SID) represented by this SecurityIdentifier object is a valid Windows account SID. |
![]() | IsEqualDomainSid | Returns a value that indicates whether the security identifier (SID) represented by this SecurityIdentifier object is from the same domain as the specified SID. |
![]() | IsValidTargetType | Returns a value that indicates whether the specified type is a valid translation type for the SecurityIdentifier class. (Overrides IdentityReference.IsValidTargetType(Type).) |
![]() | IsWellKnown | Returns a value that indicates whether the SecurityIdentifier object matches the specified well known security identifier (SID) type. |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns the security identifier (SID), in Security Descriptor Definition Language (SDDL) format, for the account represented by the SecurityIdentifier object. An example of the SDDL format is S-1-5-9. (Overrides IdentityReference.ToString().) |
![]() | Translate | Translates the account name represented by the SecurityIdentifier object into another IdentityReference-derived type. (Overrides IdentityReference.Translate(Type).) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equality | Compares two SecurityIdentifier objects to determine whether they are equal. They are considered equal if they have the same canonical representation as the one returned by the Value property or if they are both a null reference (Nothing in Visual Basic). |
![]() ![]() | Inequality | Compares two SecurityIdentifier objects to determine whether they are not equal. They are considered not equal if they have different canonical name representations than the one returned by the Value property or if one of the objects is a null reference (Nothing in Visual Basic) and the other is not. |
| Name | Description | |
|---|---|---|
![]() ![]() | MaxBinaryLength | Returns the maximum size, in bytes, of the binary representation of the security identifier. |
![]() ![]() | MinBinaryLength | Returns the minimum size, in bytes, of the binary representation of the security identifier. |
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
