Dynamic IL method causes “Operation could destabilize the runtime”

问题 System.Security.VerificationException: Operation could destabilize the runtime. at Connance.CommunicatorApi.ReportApiClient.AcknowledgeRecallsAsyncDynamicHandler(Object , AcknowledgeRecallsCompletedEventArgs ) That's the error I'm getting. What I'm trying to do (background) is create a global event handler for a class of methods. I'm working with a Static Proxy in WCF and I need to create a layer which tracks all the calls and returns to all of the WCF web methods. Unfortunately, WCF strongly

Practical example of Dynamic method?

由 ╄→гoц情女王★ 提交于 2019-12-03 05:06:53
问题 I want to learn dynamic method and its practical example using c#. Is there any relation between dynamic method and Reflection? Please help me. 回答1: We are using Dynamic methods for speed up Reflection. Here is code of our reflection optimizer. it is only 10% slower than direct call and 2000 times faster that reflection call public class ReflectionEmitPropertyAccessor { private readonly bool canRead; private readonly bool canWrite; private IPropertyAccessor emittedPropertyAccessor; private

Curiosity: Why does Expression<…> when compiled run faster than a minimal DynamicMethod?

问题 I'm currently doing some last-measure optimizations, mostly for fun and learning, and discovered something that left me with a couple of questions. First, the questions: When I construct a method in-memory through the use of DynamicMethod, and use the debugger, is there any way for me to step into the generated assembly code, when vieweing the code in the disassembler view? The debugger seems to just step over the whole method for me Or, if that's not possible, is it possible for me to

Saving a DynamicMethod to disk

问题 I have inherited code that uses DynamicMethod to generate methods at runtime. I also need to modify some of the code that is being generated. Since I am a n00b at MSIL, I would love to be able to load the generated code up in Reflector and ensure that the code does what I pray that it does ;) Only, I can't figure out how to serialize the "Anonymously Hosted DynamicMethods Assembly" to disk. Is this possible? If so, how? 回答1: I think that if you want to load the method in Reflector or dotPeek,

DynamicMethod is much slower than compiled IL function

问题 I wrote a simple object copier that copies public properties. I can't figure out why the Dynamic method is a lot slower than the c# version. Durations C# method : 4,963 ms Dynamic method : 19,924 ms Note that - as I run the dynamic method before starting the stopwatch - the duration do not include the compilation phase. I run that in Debug and Release mode, in x86 and x64 mode, and from VS and from the command line with roughly the same result (dynamic method is 400% slower). const int

Resolving the tokens found in the IL from a dynamic method

由 岁酱吖の 提交于 2019-11-29 04:49:28
Thanks to Hans Passant answering my question here: How do I get an IL bytearray from a DynamicMethod? I was able to get up and running. I am now trying to resolve the Metadata tokens found in the IL emitted, to see what methods are being called, or what not. I am able to resolve that the next token in the method body is a call. I'm using some code from Mono.Reflection 's MethodBodyReader. static byte[] GetILByteArray(Delegate @delegate){ // does stuff mentioned in other thread } ... Expression<Action> foo = () => Console.WriteLine(0); var compiled = foo.Compile(); var bytes = GetILByteArray

How to use SuperObject to invoke methods that uses an Object as parameter in Delphi?

由 江枫思渺然 提交于 2019-11-29 04:06:14
We can use the SuperObject library to invoke methods of a certain object by its name and giving its parameters as a json string using the SOInvoker method like in this answer I'd like to know how do I send a created object as a parameter. I tried to send it like LObjectList := TObjectList.Create; LSuperRttiCtx := TSuperRttiContext.Create; LSuperObjectParameter := LObjectList.ToJson(LSuperRttiCtx); SOInvoke(MyInstantiatedObject, 'MyMethod', LSuperObjectParameter); but inside MyMethod the LObjectList reference is lost. What am I doing wrong? The superobject library can be downloaded here It will

How do I get an IL bytearray from a DynamicMethod?

问题 As a bit of a novelty, I'm trying to see how different the IL from light weight code generated at runtime looks vs code generated by the VS compiler, as I noticed that VS code tends to run with a different performance profile for things like casts. So I wrote the following code:: Func<object,string> vs = x=>(string)x; Expression<Func<object,string>> exp = x=>(string)x; var compiled = exp.Compile(); Array.ForEach(vs.Method.GetMethodBody().GetILAsByteArray(),Console.WriteLine); Array.ForEach
