Struct Ref<T>

Wrapper for by-ref argument.

Implements
Inherited Members
Namespace: DotNext.Reflection
Assembly: DotNext.Reflection.dll
Syntax
public struct Ref<T> : IStrongBox, IEquatable<Ref<T>>
Type Parameters
Name Description
T

Referenced type.
Remarks

This type has special semantics when used as argument type for delegates Function<T, TArgs, TResult>, Function<TArgs, TResult>, Procedure<T, TArgs>, Procedure<TArgs> when using strongly typed reflection. Argument of this type means that it should be passed into reflected method or constructor by reference. In all other scenarios, including Unreflect<TDelegate>(ConstructorInfo) or Unreflect<TDelegate>(MethodInfo), this type treated as regular value type without special semantics.
