Marshal.PtrToStructure Method (IntPtr, Object)

Marshals data from an unmanaged block of memory to a managed object.

Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

[ComVisibleAttribute(true)] 
public static void PtrToStructure (
	IntPtr ptr,
	Object structure
)
/** @attribute ComVisibleAttribute(true) */ 
public static void PtrToStructure (
	IntPtr ptr, 
	Object structure
)
ComVisibleAttribute(true) 
public static function PtrToStructure (
	ptr : IntPtr, 
	structure : Object
)

Parameters

ptr

A pointer to an unmanaged block of memory.

structure

The object to which the data is to be copied. This must be an instance of a formatted class.

Exception typeCondition

ArgumentException

Structure layout is not sequential or explicit.

-or-

Structure is a boxed value type.

PtrToStructure is often necessary in COM interop and platform invoke when structure parameters are represented as an System.IntPtr value. You cannot use this overload method with value types.

NoteNote

This method uses SecurityAction.LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute.UnmanagedCode permission. If your code can be called from partially trusted code, do not pass user input to Marshal class methods without validation. For important limitations on using the LinkDemand member, see Demand vs. LinkDemand.
