Namespace:
System.Runtime.InteropServices System.Runtime.InteropServices System.Runtime.InteropServices System.Runtime.InteropServices

Fields

ApplicationDirectory ApplicationDirectory ApplicationDirectory ApplicationDirectory 512

Include the application directory in the DLL search path.
AssemblyDirectory AssemblyDirectory AssemblyDirectory 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 LegacyBehavior LegacyBehavior 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 SafeDirectories SafeDirectories SafeDirectories 4096

Include the application directory, the %WinDir%\System32 directory, and user directories in the DLL search path.
System32 System32 System32 System32 2048

Include the %WinDir%\System32 directory in the DLL search path.
UseDllDirectoryForDependencies UseDllDirectoryForDependencies UseDllDirectoryForDependencies UseDllDirectoryForDependencies 256

Search for the dependencies of a DLL in the folder where the DLL is located before searching other folders.
UserDirectories UserDirectories UserDirectories UserDirectories 1024

Include any path that was explicitly added to the process-wide search path by using the Win32 AddDllDirectory function.

Remarks

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