TypeAccessException Class
The exception that is thrown when a method attempts to use a type that it does not have access to.
System::Exception
System::SystemException
System::TypeLoadException
System::TypeAccessException
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
The TypeAccessException type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | TypeAccessException() | Initializes a new instance of the TypeAccessException class with a system-supplied message that describes the error. |
![]() | TypeAccessException(String) | Initializes a new instance of the TypeAccessException class with a specified message that describes the error. |
![]() | TypeAccessException(String, Exception) | Initializes a new instance of the TypeAccessException class with a specified error message and a reference to the inner exception that is the cause of this exception. |
| Name | Description | |
|---|---|---|
![]() | Data | Gets a collection of key/value pairs that provide additional user-defined information about the 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 the error message for this exception. (Inherited from TypeLoadException.) |
![]() | StackTrace | Gets a string representation of the frames on the call stack at the time the current exception was thrown. (Inherited from Exception.) |
| 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 the Object 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 a hash function for a particular type. (Inherited from Object.) |
![]() | 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.) |
TypeAccessException is thrown when a method attempts to cast an object to a type that is not accessible from the method. For example, an anonymously hosted dynamic method cannot access a security-critical type because the method is transparent. If the method contains a OpCodes::Castclass instruction that casts an object to a security-critical type, or to a generic type that has a security-critical type as one of its type parameters, TypeAccessException is thrown by the JIT compiler.
Similarly, TypeAccessException is thrown for a dynamic method that uses an internal type from another assembly. A method might not have access to its containing type, its return type, or one of its parameter types.
