DynamicObject.TryCreateInstance Method
Microsoft Silverlight will reach end of support after October 2021. Learn more.
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)
Syntax
'Declaration
Public Overridable Function TryCreateInstance ( _
binder As CreateInstanceBinder, _
args As Object(), _
<OutAttribute> ByRef result As Object _
) As Boolean
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: array<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.)
Remarks
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.
