问题 I'm trying to run a .NET MVC application on my local computer that I got from GitHub. When I hit run on Visual Studio, everything complies and a new browser window opens with the error: CS1980: Cannot define a class or member that utilizes 'dynamic' because the compiler required type 'System.Runtime.CompilerServices.DynamicAttribute' The compiler section in the same window, shows the following error: I've checked on google and this seems to be the same error. This guy was using a dynamic type

Dynamic C#.NET Webservice

问题 I am using a class in a C# ASP.NET project to allow a script written in some random scripting language to expose webservice methods dynamically - in other words, the script should be able to expose a method of any name with any signature (as long as it's valid, anyway) to the outside world through this SOAP interface (able to add and remove them at will, without needing a hard code change), and as such I need to be able to create a webservice class in C# while being able to dynamically add

Why do I get this compile error trying to call a base constructor/method that takes a dynamic argument?

问题 While refactoring some code, I came across this strange compile error: The constructor call needs to be dynamically dispatched, but cannot be because it is part of a constructor initializer. Consider casting the dynamic arguments. It seems to occur when trying to call base methods/constructors that take dynamic arguments. For example: class ClassA { public ClassA(dynamic test) { Console.WriteLine("ClassA"); } } class ClassB : ClassA { public ClassB(dynamic test) : base(test) { Console

Add property to ExpandoObject with the same name as a string

一个人想着一个人 提交于 2019-12-20 10:01:50
问题 Is there a way to add a property to an ExpandoObject with the same name as a string value? For example, if I have: string propName = "ProductNumber"; dynamic obj = new System.Dynamic.ExpandoObject(); I can create the property ProductNumber like: obj.ProductNumber = 123; But, can I create the property obj.ProductNumber based on the string propName ? So, if I don't know what the name of the property will be in advanced, I can create it based on this input. If this is not possible with

问题 consider this simple scenario: $this->method($arg1, $arg2); Solution: call_user_func_array(array($this,'method'), array($arg1, $arg2)); consider this scenario: $this->object->method($arg1, $arg2); Should this solution work? call_user_func_array(array($this->object,'method'), array($arg1, $arg2)); Or should this work? call_user_func_array(array($this, 'object','method'), array($arg1, $arg2)); Edit: Will try/catch works for SOAP exception, triger while using call_user_func? try { $soap_res =

A Regex is needed to extract the group-values. What is easiest and most efficient way to turn this file's lines into a collection of Line objects? Order of this

Dynamic Java Variable Naming

北城余情 提交于 2019-12-20 07:21:09
问题 This question is more for furthering my knowledge than anything... Does Java have anything similar to PHP's ability to generate a variable name? I have an SCJA Cert and I'm studying for the SCJP and have never seen this, but was curious. PHP Example $application->{$request->getParameter("methodCall")}($request->getParameter('value')); Does Java have anything similar? I've been reading on here and the general answer is to use a HashMap which I'm not interested in since this isn't to solve a
