问题 I'm looking for a .NET library that can generate a clean Xml tree, ideally System.Xml.XmlDocument, from invalid HTML code. I.E. it should make the kind of best effort guesses, repairs, and substitutions browsers do when confronted with this situation, and generate a pretend XmlDocument. The library should also be well-maintained. :) I realize this is a lot (too much?) to ask, and I would appreciate any useful leads. There seem to be a fair number of implementations of this for Java, but I

问题 Need any help, ideas to figure out this issue. We are working on an application that makes a call to SAP for posting some data using ERPConnect. We encounter the following issues in one of our Entity Framework call in our WCF service. We are using .NET4.0, Win 2008 Server. The following information was included with the event: exception in getting ****getrebateproposal**-****Common Language Runtime detected an invalid program.****** at System.Data.Entity.DynamicProxies.RebateProposal

问题 I need to open a writable file handle in Python and then hand off the file descriptor to a function in a .NET assembly (accessed via pythonnet's clr module. Getting from the Python file object to the win32 HANDLE* is fairly straightforward, as shown in this question: import clr from Microsoft.Win32.SafeHandles import SafeFileHandle from System.IO import FileStream, FileAccess pyf=open("c:/temp/testing123.txt","w") fileno=pyf.fileno() print fileno # 6 handle = msvcrt.get_osfhandle(fileno)

问题 What is the use of IL file generated from .NET (using MSIL assembler- ilasm.exe)? I read it from http://msdn.microsoft.com/en-us/library/496e4ekx.aspx but i am not sure about the use of IL file generated from .NET (using MSIL assembler- ilasm.exe). Can any one explain me? 回答1: You might want to use IL directly in those (admittedly rare) situations when a higher level language like C# doesn't provide the precision or features you need. For instance, there are some features in System.Dynamic

问题 I have used the following sos command to enumerate all instances of a particular type in a running asp application (hosted on windows xp 4 GB machine). .foreach (obj { !dumpheap -type ::my type:: -short ::start of address space:: ::end of address space:: }) { !objsize ${obj} }. This enumerates all objects of the given type in gc gen2. The object size on an average seems to be around 500 KB and there are around 2000 objects. This alone adds up to around 1 GB of memory whereas my asp-process

问题 Can anyone explain how the CLR handles Static classes? Does the CLR create one singleton instance for handling static classes internally? If not, why do we have a static constructor in C#? (Per my understanding, we use constructors only for instantiating the class) 回答1: First of all there is no static class in CLR. CLR doesn't know anything about static class. It is the feature of C#. Static classes are compiled into abstract as well as sealed class. Making it abstract prevent instantiation

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Troubleshooting .NET “Fatal Execution Engine Error” My code is throwing a Fatal Execution Error. The exact error is this: The runtime has encountered a fatal error. The address of the error was at 0xed40646c, on thread 0x2044. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM

问题 The documentation for converting delegates to unmanaged code states that I am responsible for preventing it's collection myself. I wish to know if the delegate cannot be collected whilst the unmanaged call is live. For example, if I do UnmanagedFunction(arg => somebody); where UnmanagedFunction does not store the function pointer beyond it's invocation. This should be legal, right? The CLR can't collect whilst the UnmanagedFunction is executing. 回答1: According to CLR Inside Out: Marshaling

问题 I was wondering why this code does not work in C++/CLI but damn easy in C#? List<Process^>^ processList = gcnew List<Process^>( Process::GetProcessesByName(this->processName));); error C2664: 'System::Collections::Generic::List::List(System::Collections::Generic::IEnumerable ^)' : cannot convert parameter 1 from 'cli::array ^' to 'System::Collections::Generic::IEnumerable ^' Here is what I come up with. Did perfectly well. :) List<Process^>^ processList = gcnew List<Process^>( safe_cast
