c#-3.0

问题 i'm fairly new to C# / .NET so I hope there is a solution for my problem. I'm working with 2 different image-processing libraries which have their own classes to represent images. Because I don't want to use this classes in my own (private) class library, I want to implement my own "myImage"-Class which is supposed to be a wrapper around both of the other classes. (I have of course to add the functionality of the libraries if they are missing). My problem is basically now like this: The

问题 Is there a way to just tell the compiler, that I want my objects to be serializable by default? 回答1: Pretty much every serialization engine is going to want to know that your objects are suitable. This can take the form of: [Serializable] / ISerializable ( BinaryFormatter , SoapFormatter ) [Serializable] / IXmlSerializable (and public ) ( XmlSerializer ) [DataContract] / [MessageContract] (or most of the above) ( DataContractSerializer and variants) AFAIK, there is no way of avoiding this

问题 i am using visual studio 2010 . when running xslt2.0 in that getting below errors xsl:value-of/* ** is not yet implemented. 'xsl:result-document'** is not yet implemented. can any one help me to reslove the above issues 回答1: If you want to use XSLT 2.0 you need to switch from XslCompiledTransform to an XSLT 2.0 processor like the .NET version of Saxon 9 or like AltovaXML or like XmlPrime. Microsoft's XslCompiledTransform is an XSLT 1.0 processor, even in .NET 4.5/VS 2012. However the named

问题 Let me start from a real life example: Customer: Alex, just noticed something strange in the RemovalProcessor at line 138: if (Session.Handler.ExecutePrefetchTasks()==null); Session.ExecuteDelayedQueries(); Should the semicolumn behind the 'if' be there? Me: Oops... I'll send this to our guys to check, but most likely, you're right. Although the case is rare, I admit nearly any big project has similar issue. I understand that semicolon (and statement block) usage rules in C# can't be changed

问题 Having coded an extension method (based on GUI update when starting event handler class on separate thread?): public static class ControlExtensions { public static TResult InvokeEx<TControl, TResult> (this TControl control, Func<TControl, TResult> func) where TControl : Control { if (control.InvokeRequired) return (TResult)control.Invoke (func, control); return func (control); } } I've been trying to unit test this method both from a UI thread and a normal thread and I can't seem to be able

问题 Here is code of very simple expression evaluator using IronRuby public class BasicRubyExpressionEvaluator { ScriptEngine engine; ScriptScope scope; public Exception LastException { get; set; } private static readonly Dictionary<string, ScriptSource> parserCache = new Dictionary<string, ScriptSource>(); public BasicRubyExpressionEvaluator() { engine = Ruby.CreateEngine(); scope = engine.CreateScope(); } public object Evaluate(string expression, DataRow context) { ScriptSource source;

问题 When I expand T4 templates inside Visual Studio, I can use the full C# 3.0 syntax, including LINQ expressions, etc. When I expand it outside Visual Studio using TextTransform.exe it complains about LINQ expressions and other new features of C# 3.0. Is there a newer version of TextTransform.exe? The one I'm running is in: C:\Program Files\Common Files\Microsoft Shared\TextTemplating\1.2\TextTransform.exe 回答1: 1.2 is the version of TextTransform that shipped with Visual Studio 2008. However, it

问题 I need to stop the execution of a method if it has not completed within a limited period of time. To do this work I can use the Thread.Abort method in this way: void RunWithTimeout(ThreadStart entryPoint, int timeout) { var thread = new Thread(() => { try { entryPoint(); } catch (ThreadAbortException) { } }) { IsBackground = true }; thread.Start(); if (!thread.Join(timeout)) thread.Abort(); } Given that I'm using .NET 3.5, is there a better way? Edit: following the comments here my entryPoint
