DllImportSearchPath Enum

Definition

Assemblies:: System.Runtime.InteropServices.dll, mscorlib.dll, netstandard.dll

Specifies the paths that are used to search for DLLs that provide functions for platform invokes.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Public Enum DllImportSearchPath

ApplicationDirectory	512	Include the application directory in the DLL search path.
AssemblyDirectory	2	When searching for assembly dependencies, include the directory that contains the assembly itself, and search that directory first. This value is used by the .NET Framework, before the paths are passed to the Win32 LoadLibraryEx function.
LegacyBehavior	0	Search the application directory, and then call the Win32 LoadLibraryEx function with the `LOAD_WITH_ALTERED_SEARCH_PATH` flag. This value is ignored if any other value is specified. Operating systems that do not support the DefaultDllImportSearchPathsAttribute attribute use this value, and ignore other values.
SafeDirectories	4096	Include the application directory, the `%WinDir%\System32` directory, and user directories in the DLL search path.
System32	2048	Include the `%WinDir%\System32` directory in the DLL search path.
UseDllDirectoryForDependencies	256	Search for the dependencies of a DLL in the folder where the DLL is located before searching other folders.
UserDirectories	1024	Include any path that was explicitly added to the process-wide search path by using the Win32 `AddDllDirectory` function.

Use the DefaultDllImportSearchPathsAttribute attribute to apply a set of paths to an entire assembly or to an individual platform invoke.
