C# (CSharp) Microsoft.Scripting.Actions MemberTracker.GetValue Beispiele

GetValue() public method

Gets the expression that creates the value. Returns null if it's an error to get the value. The caller can then call GetErrorForGet to get the correct error Expression (or null if they should provide a default).

public GetValue ( Microsoft.Scripting.Actions.Calls.OverloadResolverFactory resolverFactory, ActionBinder binder, Type type ) : DynamicMetaObject
resolverFactory	Microsoft.Scripting.Actions.Calls.OverloadResolverFactory
binder	ActionBinder
type	System.Type
return	System.Dynamic.DynamicMetaObject
