DynamicObject.TryCreateInstance Method (CreateInstanceBinder, Object[], Object)

 

Provides the implementation for operations that initialize a new instance of a dynamic object. This method is not intended for use in C# or Visual Basic.

Namespace:   System.Dynamic
Assembly:  System.Core (in System.Core.dll)

public virtual bool TryCreateInstance(
	CreateInstanceBinder binder,
	object[] args,
	out object result
)

Parameters

binder
Type: System.Dynamic.CreateInstanceBinder

Provides information about the initialization operation.

args
Type: System.Object[]

The arguments that are passed to the object during initialization. For example, for the new SampleType(100) operation, where SampleType is the type derived from the DynamicObject class, args[0] is equal to 100.

result
Type: System.Object

The result of the initialization.

Return Value

Type: System.Boolean

true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

Classes derived from the DynamicObject class can override this method to specify how a new instance of the dynamic object should be initialized. When the method is not overridden, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

C# and Visual Basic compilers never emit code to use this method because they do not support first-class types. This method is intended for languages that support the initialization of dynamic objects by using syntax like dynamic new.
