Public Class MethodAccessException
	Inherits MemberAccessException

Constructors

	Name	Description
	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)	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.

Properties

	Name	Description
	Data	Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.)
	HelpLink	Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)
	HResult	Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)
	InnerException	Gets the Exception instance that caused the current exception.(Inherited from Exception.)
	Message	Gets a message that describes the current exception.(Inherited from Exception.)
	Source	Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)
	StackTrace	Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.)
	TargetSite	Gets the method that throws the current exception.(Inherited from Exception.)

Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetBaseException()	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetObjectData(SerializationInfo, StreamingContext)	When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)
	GetType()	Gets the runtime type of the current instance.(Inherited from Exception.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Creates and returns a string representation of the current exception.(Inherited from Exception.)

Events

	Name	Description
	SerializeObjectState	Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

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.
