Public methodFileLoadException()Initializes a new instance of the FileLoadException class, setting the Message property of the new instance to a system-supplied message that describes the error, such as "Could not load the specified file." This message takes into account the current system culture.
Public methodFileLoadException(String)Initializes a new instance of the FileLoadException class with the specified error message.
Protected methodFileLoadException(SerializationInfo, StreamingContext)Initializes a new instance of the FileLoadException class with serialized data.
Public methodFileLoadException(String, Exception)Initializes a new instance of the FileLoadException class with a specified error message and a reference to the inner exception that is the cause of this exception.
Public methodFileLoadException(String, String)Initializes a new instance of the FileLoadException class with a specified error message and the name of the file that could not be loaded.
Public methodFileLoadException(String, String, Exception)Initializes a new instance of the FileLoadException class with a specified error message, the name of the file that could not be loaded, and a reference to the inner exception that is the cause of this exception.

Public methodGetBaseExceptionWhen overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetObjectDataSets the SerializationInfo with the file name and additional exception information. (Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).)

Represents the error that occurs when a Assembly file is found but cannot be loaded.

The FileNotFoundException exception is thrown when the file fails to load because it cannot be located. If the file is located, but cannot be loaded due to insufficient permissions, a SecurityException is thrown.

FileLoadException has the default HRESULT of COR_E_FILELOAD, which has the value 0x80131621, but this is not the only possible HRESULT.

If your code does not have PathDiscovery permission, the error message for this exception may only contain file or directory names instead of fully qualified paths.

NoteNote

This exception is not included in the .NET for Windows Store apps or the Portable Class Library, but it is thrown by some members that are. To catch the exception in that case, write a catch statement for IOException instead.
