白昼怎懂夜的黑 提交于 2019-12-10 23:35:25
问题 When including any managed class to my managed unit test the compile spits out these errors: 1>UnitTest.obj : error LNK2020: unresolved token (0A000360) "extern "C" int __cdecl _CrtDbgReportW(int,wchar_t const *,int,wchar_t const *,wchar_t const *,...)"

C++/CLI What class encloses global functions?

风格不统一 提交于 2019-12-10 21:48:59
问题 If I remember correctly, functions must be a member of a class in the CLR world, and yet global functions are possible in C++/CLI. Does this mean that these global functions are part of a hidden "global" class of some sort? If so, how would one go about getting its type, for reflection purposes? 回答1: Yes, .NET metadata supports global functions and variables. Called the "Global Class" in CLR source code, its name is <Module> . Using C# vernacular, it is internal , abstract and sealed to

How to prove that the .NET CLR JIT compiles every method only once per run?

旧时模样 提交于 2019-12-10 21:06:30
问题 There's an old question asking whether C# is JIT compiled every time and the answer by famous Jon Skeet is: "no, it's compiled only once per application" as long as we're talking about desktop applications which are not NGENed. I want to know if that information from 2009 is still true and I want to figure that out by experiment and debugging, potentially by putting a breakpoint on the JITter and using WinDbg commands to inspect objects and methods. My research so far I know that the .NET

Can we construct an instance of `OpCode`?

问题 The .NET Framework 4.0 introduces several items to the Reflection API that range from extremely useful to vital for my work. Among these are protected constructors for Assembly , Module , MethodBody , and LocalVariableInfo and the new CustomAttributeData class. There are a couple items I still need that are quite troublesome to work around. I believe they easily apply to the same [small] group of people would need to extend the types I just listed. This time : I'm looking for a way to

Passing a DataTable into a Stored Procedure. Is there a better way?

二次信任 提交于 2019-12-10 20:38:45
问题 Can A datatable somehow be passed into SQL Server 2005 or 2008 ? I know the standard way seesm to be passing XML to a SP. And a datatable can easily be converted to XML somehow to do that. What about passing a .NET object into a SP ? Is that possible ? I remember hearing about SQL and CLR working together in 2008 somehow but I never understood.. Maybe that means you can refer to .NET objects within a Stored Procedure ? 回答1: You can create a User-defined table type in SQL. Then, in the stored

What is the effect of setting (or not) .NET CLR version in ASP.Net Core?

陌路散爱 提交于 2019-12-10 20:10:47
问题 What is the point of setting "No Managed Code" .NET CLR version for an IIS Asp.NET Core application pool? Documentation says that ASP.NET Core runs in a separate process and manages the runtime. ASP.NET Core doesn't rely on loading the desktop CLR. Setting the .NET CLR version to No Managed Code is optional . Since it is optional , what are the drawbacks of keeping the default v4.0 ? Why the documentation explicitly instructs to set it to "No Managed Code"? It's not very clear whether there

IL / CLR / DLR References?

让人想犯罪 __ 提交于 2019-12-10 18:31:42
问题 I'm wanting to learn more about IL and CLR / DLR under the hood. A friend of mine recommended the book "Inside Microsoft .NET IL Assembler", but since it came out in 2002 I fear it's pretty out of date at this point. Does anyone have any more up-to-date books or websites that can be used by someone who understands .NET languages to learn more about the inner workings of IL and the CLR? 回答1: Perhaps my answer is a bit late now, but the book "MS Press - Inside Microsoft .NET IL Assembler" is

Using .NET Framework 3.5 in a SQL Server 2005 Stored Procedure

时光毁灭记忆、已成空白 提交于 2019-12-10 18:18:22
问题 I have an SQL Server 2005 server, and I'd like to run a .Net CLR stored procedure on it. However, I'd like to use .NET Framework 3.5. If I try this right now, I get this error: Error: Assembly 'system.core, version=3.5.0.0, culture=neutral, publickeytoken=b77a5c561934e089.' was not found in the SQL catalog. I'm told this is possible in SQL Server 2008, because SQL Server 2008 ships with .NET Framework 3.5. However, I'm wondering if there's a way to add .NET Framework 3.5 to my SQL Server 2005

Nullable<> types are a BCL, CLR, or both implementation?

我怕爱的太早我们不能终老 提交于 2019-12-10 17:55:49
问题 Some time ago I thought that Nullable<> value types are classes, encapsulating value types and a bool to HasValue. With some implicit cast operador for null, just implemented at BCL. But being a struct, how this can be achieved? Nullable<> struct is "special" for CLR? 回答1: Nullable<T> is defined as a normal struct, but there's special hooks within the CLR to box/unbox an instance of [mscorlib]System.Nullable`1 to null according to the HasValue property. There's more details on this here 回答2:

Boxing and Unboxing [duplicate]

我是研究僧i 提交于 2019-12-10 17:23:10
问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: What is boxing and unboxing and what are the trade offs? Ok I understand the basic concept of what happens when you box and unbox. Box throws the value type (stack object) into a System.Object and stores it on the heap Unbox unpackages that object on the heap holding that value type and throws it back on the stack so it can be used. Here is what I don't understand: Why would this need to be done...specific real
