Definition

Namespace:

System.CommandLine.Binding

Assembly:

System.CommandLine.dll

Tries to get a value from a binding context. The return value indicates whether a value matching the specified value descriptor was present.

 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
