在使用reflection时，如何确定方法是否返回动态类型？

使用reflection时，可以检查DynamicAttribute属性的字段，属性，索引器和参数，以确定它们具有动态类型。 但是，这对于Methods不起作用 – 即使它们返回’dynamic’，它们也没有属性，它们的返回类型是’object’（也没有属性）。 Visual Studio为intellisense为外部程序集中的方法执行此操作…可以使用reflection来完成吗？

例如，下面的代码生成此输出：

dynamicField is dynamic DynamicProperty is dynamic Item is dynamic DynamicMethod is NOT dynamic!! dynamicParameter is dynamic 

示例代码：

 using System; using System.Reflection; using System.Runtime.CompilerServices; namespace ReflectDynamics { class Program { static void Main() { var test = typeof(Test); CheckDynamic(test.GetField("dynamicField")); CheckDynamic(test.GetProperty("DynamicProperty")); CheckDynamic(test.GetProperty("Item")); MethodInfo dynamicMethod = test.GetMethod("DynamicMethod"); CheckDynamic(dynamicMethod); CheckDynamic(dynamicMethod.GetParameters()[0]); Console.ReadKey(); } static void CheckDynamic(MemberInfo memberInfo) { bool isDynamic = memberInfo.GetCustomAttributes(typeof(DynamicAttribute), true).Length > 0; Console.WriteLine(memberInfo.Name + (isDynamic ? " is dynamic" : " is NOT dynamic!!")); } static void CheckDynamic(ParameterInfo parameterInfo) { bool isDynamic = parameterInfo.GetCustomAttributes(typeof(DynamicAttribute), true).Length > 0; Console.WriteLine(parameterInfo.Name + (isDynamic ? " is dynamic" : " is NOT dynamic!!")); } } class Test { public dynamic dynamicField; public dynamic DynamicProperty { get { return dynamicField; } } public dynamic this[int index] { get { return dynamicField; } } public dynamic DynamicMethod(dynamic dynamicParameter) { return dynamicField; } } } 

 static void CheckDynamic(MemberInfo memberInfo) { bool isDynamic = memberInfo.GetCustomAttributes(typeof(DynamicAttribute), true).Length > 0; var methodInfo = (memberInfo as MethodInfo); if (methodInfo != null) { isDynamic = methodInfo.ReturnTypeCustomAttributes.GetCustomAttributes(typeof(DynamicAttribute), true).Length > 0; } Console.WriteLine(memberInfo.Name + (isDynamic ? " is dynamic" : " is NOT dynamic!!")); }
