Definition

Visual Basic	Public Function LockBox( _     ByVal typeLock As Type, _     ByVal level As Integer, _     ByVal box As Box, _     ByVal flags As LockFlags, _     ByVal ranks() As Integer _ ) As Array
C#	public Array LockBox(     Type typeLock,     int level,     Box box,     LockFlags flags,     int[] ranks );
C++	public: Array^ LockBox(     Type^ typeLock,     int level,     Box box,     LockFlags flags,     array<int>^ ranks );
JScript	public function LockBox(     typeLock : Type,     level : int,     box : Box,     flags : LockFlags,     ranks : int[] ) : Array;

Parameters

typeLock	System.Type A Type object that indicates the type of data to return. This can be a value type or any type that contains only value types.
level	System.Int32 Value that specifies a level of the texture resource to lock.
box	Microsoft.DirectX.Direct3D.Box A Box structure that indicates the region to lock. Omitting this parameter locks the entire volume level.
flags	Microsoft.DirectX.Direct3D.LockFlags Zero or more locking flags that describe the type of lock to perform. For this method, the valid flags are Discard, NoDirtyUpdate, NoSystemLock, and ReadOnly. For a description of the flags, see LockFlags.
ranks	System.Int32[] Array of one to three Int32 values that indicate the dimensions of the returning Array.

Return Value

System.Array
An Array object that describes the locked region.

Remarks

For performance reasons, dirty regions are recorded only for level 0 of a texture. Dirty regions are automatically recorded when Texture.LockRectangle is called without NoDirtyUpdate or ReadOnly. For more information, see Device.UpdateTexture.

Exceptions

InvalidCallException

The method call is invalid. For example, a method's parameter might contain an invalid value.
