MissingManifestResourceException Class

Updated: October 2010

The exception thrown if the main assembly does not contain the resources for the neutral culture, and they are required because of a missing appropriate satellite assembly.

Namespace:  System.Resources
Assembly:  mscorlib (in mscorlib.dll)
[SerializableAttribute]
[ComVisibleAttribute(true)]
public class MissingManifestResourceException : SystemException

A MissingManifestResourceException is thrown when the attempt to retrieve a resource fails because the resource set for the neutral culture could not be loaded from a particular assembly. Note that even though the exception is thrown when you attempt to retrieve a particular resource, it is caused by the failure to load the resource set rather than the failure to find the resource. The main causes of the exception include the following:

  • The resource set is not identified by its fully qualified name. For example, if the baseName parameter in the call to the ResourceManager.ResourceManager(String, Assembly) method includes the root name of the resource set without a namespace, but the resource set is assigned a namespace when it is stored in its assembly, the call to the ResourceManager.GetStringmethod throws this exception. You can determine the namespace of the resource set by examining its assembly with a reflection tool such as MSIL Disassembler (Ildasm.exe).

  • The resource set is identified by its resource file name and its file extension. For example, this exception is thrown if the neutral culture's resource set is named GlobalResources and you supply a value of "GlobalResources.resources" to the baseName parameter of the ResourceManager.ResourceManager(String, Assembly) constructor.

  • The culture-specific resource set identified in a method call cannot be found, and the fallback resource set cannot be loaded. For example, if you create satellite assemblies for the English (United States) and Russia (Russian) cultures but you fail to provide a resource set for the neutral culture, this exception is thrown if your application's current culture is English (Great Britain).

MissingManifestResourceException uses the HRESULT COR_E_MISSINGMANIFESTRESOURCE which has the value 0x80131532.

MissingManifestResourceException uses the default Equals implementation, which supports reference equality.

For a list of initial property values for an instance of MissingManifestResourceException, see the MissingManifestResourceException constructors.

NoteNote:

We strongly recommend that your main assembly contain a neutral set of resources, so if a satellite assembly is unavailable, your application will not fail.
