Specifies the paths that are used to search for DLLs that provide functions for platform invokes.
Assembly: mscorlib (in mscorlib.dll)
Initializes a new instance of theclass, specifying the paths to use when searching for the targets of platform invokes.
This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)
Returns the hash code for this instance.(Inherited from Attribute.)
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
Returns a string that represents the current object.(Inherited from Object.)
|_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)|
Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)
|_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)|
Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)
Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)
|_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)|
Provides access to properties and methods exposed by an object.(Inherited from Attribute.)
When applied to an assembly, this attribute specifies the paths that are used by default to search for any DLL that provides a function for a platform invoke, in any code in the assembly. When applied to an individual platform invoke, this attribute overrides the default search paths that were specified for the assembly.
This attribute is ignored for any platform invoke that specifies an absolute path.
Use this attribute to prevent the Win32 LoadLibraryEx function from searching the current working directory. This helps protect your application from attacks in which malicious software places a DLL in the current working directory, so that when a platform invoke calls the Win32 LoadLibraryEx function, the function's default search order finds the malicious DLL instead of the system DLL it was intended to find.
The common language runtime handles the call to the LoadLibraryExfunction according to the following algorithm:
If the attribute is applied to an individual platform invoke, use the values specified by that instance of the attribute.
Otherwise, if the attribute is applied to the assembly that contains the platform invoke, use the values specified by that instance of the attribute.
Otherwise, search the assembly directory and then call the LoadLibraryEx function with the LOAD_WITH_ALTERED_SEARCH_PATH flag.
