Hi, I'm trying to insert into XML column (SQL SERVER 2008 R2), but the server's complaining: System.Data.SqlClient.SqlException (0x80131904): XML parsing: line 1, character 39, unable to switch the encoding I found out that the XML column has to be UTF-16 in order for the insert to succeed. The code I'm using is: XmlSerializer se...
Folks, I know LINQ has a SequenceEquals method. This method makes sure each item value in each collection matches, in the same order. What I'm looking for is a more "Equivalent" type of functionality. Just that both sequences contain the same items, not necessarily in the same order. For example, nUnit has CollectionAssert.AreEqual(...
[Serializable] class MyClass { [NonSerialized] int Foo { get; set; } // error [NonSerialized] int bar; // ok } Why is this disallowed? I know about the workarounds such as implementing ISerializable switching to XmlSerializer/XmlIgnore switching to a manually-implemented property The question is specifically why is [NonSer...
XmlDocument doc = new XmlDocument(); doc.AppendChild(doc.CreateElement("Foo")); doc.DocumentElement.InnerXml = "Test"; StringBuilder result = new StringBuilder(); doc.WriteContentTo(XmlWriter.Create(result)); At the end, result is: <Foo>Test that means the end element is missing. Why is ...

Identical to "How do exceptions work (behind the scenes) in C++", but for C#. I know that the steps below have to be performed when an exception is thrown. Find the nearest handler for the exception type; Unwind the stack up to the handler level; Call the handler; Find and call every finally blocks. How does .NET handles these opera...
This is mostly for educational purposes. I'm trying to create the InputMapper class, which is used in this example: var mapper = new InputMapper<SomeType>(); mapper.Map("some user input", someType => someType.IntProperty, "Input was not an integer"); mapper.Map("some user input", someType => someType.BoolProperty, "Input was not a bool"...

Hello I'm referencing a .NET DLL (which in turn references a lot of legacy COM DLLs) which is NOT strongly named. I'm referencing this from an NUnit project, which is also not signed. However when running and trying to instantiate a class, I receive the error message: RegistrationException: The class XXX does not have a strong name. ...

a strange idea comes to me when I'm reading APUE(Advanced Programming in UNIX Environment). It seems that in UNIX's error handling, it has 2 types of error(FATAL & INFATAL). I feel like it's something related to checked and unchecked Exceptions in JAVA. So, to sum up, in a program, you has 2 kinds of errors, one of them is critical and...
The oracle .net client is a big pain to install and manage. So what experience have people got with alternatives? (Telling the customer that you only support Sql Server is not always an option) ...

How can I retrieve the client rectangle (of a control) out of a Graphics object? I think the Graphics object should know its coordinates of the area to draw in, but I don't see how to actually get it. Edit: As stated in the answers, there should be access to the Control that the Graphics object was created for. This would obviously solv...
We're currently developing an add-in for some software. We decided to develop in .NET, even though the application is written in some native language. Since there were some problems directly creating the external interface in .NET, we decided to build a bridge DLL in C++/CLI, which does some basic initialization and then loads our manage...
I'm kind of new to the design patterns concept. C# is my primary programming language. (I use VB from time to time). I don't want to write sloppy code which is inflexible, not extendable and buggy. Whenever I see a design pattern in action, I enjoy the logic behind it and understand it well, But unfortunately, I'm having trouble implemen...
