StateMachineAttribute StateMachineAttribute StateMachineAttribute StateMachineAttribute Class

Definition

Allows you to determine whether a method is a state machine method.

public ref class StateMachineAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Method, AllowMultiple=false, Inherited=false)]
[System.Serializable]

Remarks

You should not apply the StateMachine attribute to methods in your code. For methods that are state machine methods, the compiler will apply the AsyncStateMachineAttribute or IteratorStateMachineAttribute in the emitted IL.

When checking whether a method is a state machine method, it is preferable to instead check for following attributes, which are derived from StateMachineAttribute:

Note

StateMachineAttribute cannot be used to check whether a method is a state machine method if the method is an iterator method in C#.

Constructors

StateMachineAttribute(Type) StateMachineAttribute(Type) StateMachineAttribute(Type) StateMachineAttribute(Type)

Initializes a new instance of the StateMachineAttribute class.

Properties

StateMachineType StateMachineType StateMachineType StateMachineType

Returns the type object for the underlying state machine type that was generated by the compiler to implement the state machine method.

TypeId TypeId TypeId TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.

Methods

Equals(Object) Equals(Object) Equals(Object) Equals(Object)

Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)
GetHashCode() GetHashCode() GetHashCode() GetHashCode()

Returns the hash code for this instance.

(Inherited from Attribute)
GetType() GetType() GetType() GetType()

Gets the Type of the current instance.

(Inherited from Object)
IsDefaultAttribute() IsDefaultAttribute() IsDefaultAttribute() IsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(Inherited from Attribute)
Match(Object) Match(Object) Match(Object) Match(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(Inherited from Attribute)
MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString() ToString() ToString() ToString()

Returns a string that represents the current object.
