Assembly::GetManifestResourceStream Method (Type^, String^)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Loads the specified manifest resource, scoped by the namespace of the specified type, from this assembly.

Namespace:   System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

virtual Stream^ GetManifestResourceStream(
	Type^ type,
	String^ name


Type: System::Type^

The type whose namespace is used to scope the manifest resource name.

Type: System::String^

The case-sensitive name of the manifest resource being requested.

Return Value

Type: System.IO::Stream^

The manifest resource; or null if no resources were specified during compilation or if the resource is not visible to the caller.

Exception Condition

The name parameter is null.


The name parameter is an empty string ("").


A file that was found could not be loaded.


name was not found.


name is not a valid assembly.


Resource length is greater than Int64::MaxValue.

For example, if the full name specified for type is "MyNameSpace.MyClasses" and name is "Net", this method overload searches for a resource named "MyNameSpace.Net".

A manifest resource is a resource (such as an image file) that is embedded in the assembly at compile time. For more information about manifest resources, see Microsoft .NET Framework Resource Basics in the MSDN Library.

Resource information is returned only if the resource is visible to the caller, or the caller has ReflectionPermission.


This method returns null if a private resource in another assembly is accessed and the caller does not have ReflectionPermission with the ReflectionPermissionFlag::MemberAccess flag.

If the assembly manifest lists a resource file, GetManifestResourceStream returns a Stream object even if the resource file cannot be found on disk at the time. If the resource file is not found, passing the resulting Stream object to the ResourceReader constructor causes an ArgumentException.
