BinderBase<T>.IValueSource.TryGetValue Método

Definição

Namespace:

System.CommandLine.Binding

Assembly:

System.CommandLine.dll

Tenta obter um valor de um contexto de associação. O valor retornado indica se um valor correspondente ao descritor de valor especificado estava presente.

 virtual bool System.CommandLine.Binding.IValueSource.TryGetValue(System::CommandLine::Binding::IValueDescriptor ^ valueDescriptor, System::CommandLine::Binding::BindingContext ^ bindingContext, [Runtime::InteropServices::Out] System::Object ^ % boundValue) = System::CommandLine::Binding::IValueSource::TryGetValue;

bool IValueSource.TryGetValue (System.CommandLine.Binding.IValueDescriptor valueDescriptor, System.CommandLine.Binding.BindingContext? bindingContext, out object? boundValue);

abstract member System.CommandLine.Binding.IValueSource.TryGetValue : System.CommandLine.Binding.IValueDescriptor * System.CommandLine.Binding.BindingContext * obj -> bool
override this.System.CommandLine.Binding.IValueSource.TryGetValue : System.CommandLine.Binding.IValueDescriptor * System.CommandLine.Binding.BindingContext * obj -> bool

Function TryGetValue (valueDescriptor As IValueDescriptor, bindingContext As BindingContext, ByRef boundValue As Object) As Boolean Implements IValueSource.TryGetValue

bindingContext

BindingContext

O contexto de associação do qual associar o valor.

boundValue

Object

Quando esse método retorna, contém o valor associado.
