Remarks

Note

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 MemberAccessException instead.

This exception is thrown in situations such as the following:

  • A private, protected, or internal method that would not be accessible from normal compiled code is accessed from partially trusted code by using reflection.

  • A security-critical method is accessed from transparent code.

  • The access level of a method in a class library has changed, and one or more assemblies that reference the library have not been recompiled.

Note

Beginning with the .NET Framework 4, the common language runtime treats application code as transparent when it is run with partial trust. See Security Considerations for Reflection.

MethodAccessException uses the HRESULT COR_E_METHODACCESS, that has the value 0x80131510.

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

Constructors

MethodAccessException()

Initializes a new instance of the MethodAccessException class, setting the Message property of the new instance to a system-supplied message that describes the error, such as "Attempt to access the method failed." This message takes into account the current system culture.
MethodAccessException(SerializationInfo, StreamingContext)
Obsolete.

Initializes a new instance of the MethodAccessException class with serialized data.
MethodAccessException(String)

Initializes a new instance of the MethodAccessException class with a specified error message.
MethodAccessException(String, Exception)

Initializes a new instance of the MethodAccessException class with a specified error message and a reference to the inner exception that is the cause of this exception.
