问题 Has anyone seen a RedirectedThreadFrame in a callstack in windbg? That is from the managed callstack. I am seeing alot of exceptions being thrown inside the framework that I am never seeing bubbled to me and I am trying to figure out why. The native callstack just has: 0526f6b0 79f63d27 KERNEL32!RaiseException+0x53 0526f718 79f64102 mscorwks!Thread::RedirectedHandledJITCase+0x198 0526f720 00000000 mscorwks!Thread::RedirectedHandledJITCaseForGCThreadControl+0x7 The managed callstack has:

问题 I create a CLR project in visual c++ with 64 bit configuration, and try to use cpprestsdk aka casablanca 64bit . But when I run the project, an error occured: 1>------ Build started: Project: Timestamp, Configuration: Debug x64 ------ 1>MyForm.cpp 1>c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.13.26128\include\mutex(8): fatal error C1189: #error: <mutex> is not supported when compiling with /clr or /clr:pure. 1>Testapi.cpp 1>c:\program files (x86)\microsoft

问题 Am I able to embed the .net runtime so that .net is not required on the host operating system? I was looking at doing this with Mono by looking here: http://mono-project.com/Embedding_Mono but seems to allude to using external modules to accomplish this. My goal is to have one single executable with no installed .net runtime. I do not know how this would be configured in my application to compile the native code, link the mono runtime- as well as compile the C# code and link that as well? 回答1

问题 Why this code http://ideone.com/YRcICG void Main() { double a = 0.00004; Int32 castToInt = (Int32)(1.0/a); Int32 convertToInt = Convert.ToInt32(1.0/a); Console.WriteLine("{0} {1:F9} {2:F9}", castToInt == convertToInt, castToInt, convertToInt); Console.WriteLine((((int)(1.0/(1.0/25000))) == 24999)); } results in False 24999,000000000 25000,000000000 True in context of CLR/C# implementation 回答1: The trick lies in the way the double is represented so (1.0/a) will be represented in the following

问题 Can the resources of one machine in a web farm be affected to such a point by an app running with Garbage Collection Mode = "server mode" such that the network load balancer will adjust for it? 回答1: Network load balancer is not "sensitive" to GC, in a sense it doesn't know when or where it happens. It may attempt to do some funky stuff with checking the "load" on the machine, but usually it hurts performance and a simple round robin turns out to be better a approach for most of the scenarios.

问题 I'm interested in using an "unrolled linked list" in my C# application. Is anyone aware of a stable implementation, especially one that will allow me to configure how much padding to allocate per array? 回答1: According to the 2nd comment in your own link, such a list should be implemented in BigList in the PowerCollections library. It's open source, so you could have a look at the code and see if it allows for your scenario, or if it can be adapted to fit your needs easily. Other than that, I

问题 Quoted from CLR via C#, it reads to me as if call would search for the method that is defined by a base type at runtime via CLR. Then call IL instruction is used to call an instance or virtual method, you must specify a variable that refers to an object. The type of the variable itself indicates which type defines the method that the CLR should call. If the variable's type doesn't define the method, base types are checked for a matching method. and When calling a non-virtual instance method,

问题 In a thread resolved yesterday, @hvd showed me how to get "control" over exception handling by .Invoke when dealing with delegates of unknown type (an issue seen in libraries like Isis2, where the end-user provides polymorphic event handlers and the library type-matches to decide which to call). Hvd's suggestion revolved around knowing how many arguments the upcall handler received and then using that information to construct a generic of the right type, which allowed him to construct a

问题 What is the value in memory of, for example, integer value (int) after declaration but not initialization? In "CLR vi C#" Richter writes, that value types is initialized with 0, but not allowed to be used. So what will be in memory after declaration of variable like this int testVar; And how is mechanism of initializing check implemented? 回答1: Types are initialized with memory that is all zeros. I don't know if this is according to the specification for all value types so you can't count on

问题 I'm attempting to invoke Windows Powershell cmdlets via Visual Studio .NET. However, I'm getting the exception shown below when I try to call a function.The Microsoft.PowerShell.ConsoleHost.dll wasn't initially in that path so I copied it over from another location. Is this the right way of installing a snap-in? It still spits out that exception and I'm not sure why. Any nudges in the right direction would be very helpful. Thanks.
