![]() ![]() Get Calling Method using Reflection To get name of calling method use method StackTrace.GetFrame. Then use the class mentioned in the answers (from Mono.Reflection) to do your inspection. Start with this SO question: C# reflection and finding all references. ![]() What you need to do is use an IL disassembler (which is achievable within the namespace) to find the Operand that contains the parameter value you're looking for. C# Reflection get calling method parameters Specify Type.EmptyTypes for no parameters in the constructor. GetConstructor(Type types): Search for public constructor which match the types as parameters. C# reflection provides two main overloads of GetConstructor methods. Until you provide the types of the method parameters, it is not known which method you are referring to. "ToString" or "GenericMethod" actually refers to a group of methods that may contain one or more methods. MethodInfo.GetCurrentMethod () will give you information about the current method and then get information about the parameters using GetParameters (). returns true if the declaration of the parameter is with the ByRef keyword, and returns false if the declaration is with the ByVal keyword (regardless of whether the type of the parameter is by-value (e.g., structure) or by-reference (e.g., class)). For example, suppose that class B inherits from class A and both implement a virtual method named M. Reflection uses dynamic method lookup when invoking virtual methods. If a parameter of the current method is a value type, and the corresponding argument in parameters is null, the runtime passes a zero-initialized instance of the value type. If one of those conditions is violated, it raises an exception on behalf of the caller. You can get the parameter names and types, but not the parameters themselves.Įssentially, this code uses reflection to check to ensure that none of the parameters of a method are nulland none of the strings are empty or consist only of whitespace. ![]() You'd have to use the debugging/profiling API. You can't get method parameter values from reflection. NET Framework, including Managed Extensibility Framework (MEF), Charting Controls, CardSpace, Windows Identity Foundation (WIF), Point of Sale (POS), Transactions. NET Framework Also discuss all the other Microsoft libraries that are built on or extend the. Get method parameter's values using reflection. In this article, you will see the Parameter Log utility class, which we can use to trace parameter values during an exception. Log all the parameters passed to some method in C#. You would need to call LogParameters like below since you wouldn't be able to get the reflected values of integerParameter and stringParameter from ParameterInfo. ![]() This should give you your desired results and allow you to execute the code below in LogParameters(). Note, GetFrame(1) gets the calling method rather than the current method. Check the string first not the null because the string requires special handling. Use a foreach to loop over both the arguments and their corresponsing parameter info at the same time. Get the stack trace by skipping the first frame (you don't need it). You can determine whether a property is indexed or not by calling the GetIndexParameters method. You call the GetValue (Object) overload to retrieve the value of a non-indexed property if you try to retrieve the value of an indexed property, the method throws a TargetParameterCountException exception. I also want to retrieve the parameter value (without using something like public void SendErrorMail(string exeptionMessage, params object parameters) as functionality is lost this way) in code within the method. The example defines a delegate named MyDelegate and an event named ev of type MyDelegate. The following example uses the GetParameters method to retrieve the parameters of the Invoke method of a delegate. If you'd like to get the value of a specific field or property you need to use an instance as well (like you already know).Įxamples. Because reflection returns the metadata information. You cannot get the value of the method's parameters using reflection. C# reflection get method parameter values ![]()
