public sealed class CallOnce

The CallOnce type exposes the following members.

Properties

	Name	Description
	CurrentTask	Gets the current Task. The task can used to await for the execution of the encapsulated method.
	IsWaiting	Gets a value that indicates that the call is still waiting for its execution.

Methods

	Name	Description
	Create(Action)	Creates a new instance of CallOnce that encapsulates a method that has no parameters and has no return value.
	Create(Func<Task>)	Creates a new instance of CallOnce that encapsulates a method that has no parameters and has no return value.
	Create(Object, Action)	Creates a new instance of CallOnce that encapsulates a method that has no parameters and has no return value.
	Create(Object, Func<Task>)	Creates a new instance of CallOnce that encapsulates a method that has no parameters and has no return value.
	Invoke	Invokes the encapsulated method.

Events

	Name	Description
	Invoked	Occures if the action has been invoked.

Extension Methods

	Name	Description
	As(Type)	Overloaded. Converts a type using the implicit or explicit operators. If both fails it will try to convert the value with ChangeType(Object, Type). (Defined by ExtensionsConvertions.)
	As(Type, Type)	Overloaded. Converts a type using the implicit or explicit operators. If both fails it will try to convert the value with ChangeType(Object, Type). (Defined by ExtensionsConvertions.)
	As<T>()	Overloaded. Performs a cast between compatible reference types. If a convertion is not possible then null is returned. As a last resort it will use ChangeType(Object, Type). Tries to use the implicit and explicit operators if exists when convertion with 'as' returns null. (Defined by ExtensionsConvertions.)
	CreateType<T>	Creates a new Type that implements the properties of an interface defined by T and copies all value of anon to the new object. (Defined by ExtensionsInterception.)
	GetPropertyNonPublicValue<T>	Searches for the specified property, using the specified binding constraints and returns its value. Default BindingFlags are Instance and NonPublic (Defined by ExtensionsReflection.)
	GetPropertyValue(String, BindingFlags)	Overloaded. Searches for the specified property, using the specified binding constraints and returns its value. (Defined by ExtensionsReflection.)
	GetPropertyValue<T>(String)	Overloaded. Searches for the specified property, using the specified binding constraints and returns its value. Default BindingFlags are Instance and Public (Defined by ExtensionsReflection.)
	GetPropertyValue<T>(String, BindingFlags)	Overloaded. Searches for the specified property, using the specified binding constraints and returns its value. (Defined by ExtensionsReflection.)
	MapTo<T>	Maps all properties and fields of an instance to another instance. The Clone() method is used to copy an instance if exist. Mapping fails on jagged and multidimensional array. Classes without parameterless constructor will stay null. (Defined by ExtensionsCloning.)
	ToLong	Tries to convert a Object to an Int64. Returns MinValue if target cannot be parsed. (Defined by ExtensionsConvertions.)
	ToStringEx(String)	Overloaded. Converts the value of this instance to its equivalent string representation, using the specified format. The following custom formatter are already added: ByteSizeFormatter, MetricUnitFormatter (Defined by Extensions.)
	ToStringEx(String, CultureInfo)	Overloaded. Converts the value of this instance to its equivalent string representation, using the specified format. The following custom formatter are already added: ByteSizeFormatter, MetricUnitFormatter (Defined by Extensions.)
	TryDispose	Tries to performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. This will dispose an object if it implements the IDisposable interface. (Defined by Extensions.)
