partial-classes

问题 Update from comment: I need to extend linq-to-sql classes by own parameters and dont want to touch any generated classes. Any better suggestes are welcome. But I also don't want to do all attributes assignments all time again if the linq-to-sql classes are changing. so if vstudio generates new attribute to a class i have my own extended attributes kept separate, and the new innerited from the class itself Original question: i'm not sure if it's possible. I have a class car and a class mycar

问题 I have created a partial class for my xsd auto generated class. The problem is in debugging this partial class. Breakpoint are not recognized or the compiler doesn't break at the breakpoints set in the partial class. // Autogenerated class by xsd.exe public partial class Class1 { private Class1Brand[] brandField; private string Class1guidField; ..... } // Debug Part - probably in a different file public partial class Class1 { public static Validity setValidity(Validity validity) { // ********

问题 Consider a class which implements a lot of interfaces, would it make sense to implement each interface in a separate file using partial class definitions? Would this be an abuse of the language feature or is it an idiom I'm unaware of? 回答1: If your class has to implement many interfaces, that's a reasonable way of managing the source, yes. You can edit the project file to make several of them depend on one "main" class file, which makes the Solution Explorer easier to work with. You should

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 2 years ago . Okay, so we have a utility here in-house that generates business-model classes from our database tables and views, similar to (but not quite exactly like) an ORM. In maintaining it, it occurred to me that the data in the schemas isn't likely going to change a whole lot. The

问题 I'm very new to C# so please bear with me... I'm implementing a partial class, and would like to add two properties like so: public partial class SomeModel { public bool IsSomething { get; set; } public List<string> SomeList { get; set; } ... Additional methods using the above data members ... } I would like to initialize both data members: IsSomething to True and SomeList to new List<string>() . Normally I would do it in a constructor, however because it's a partial class I don't want to

问题 I’m working on some partial classes but I can’t figure out how to do it.

问题 I have a generic abstract UserControl class, SensorControl , which I want all my sensor control panels to inherit from. The problem When attempting to design the EthernetSensorControl (one of my inherited UserControl forms, from within Visual Studio, the following error is displayed in the form designer: The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: DeviceSensorControl --- The base

问题 I have a partial that is split over two namespaces. The problem is that if I have an interface implemented on one of the partials, it is not recognized on the counterpart partial class. For example, I would expect the below to return true for being recognized as ILastModified (C# fiddle at http://ideone.com/heLDn0): using System; using MyNamespace.One; public class Test { public static void Main() { var item = new Product(); Console.WriteLine(item is ILastModified); //RETURNS FALSE??! } }

问题 I used the xsd.exe tool to generate a class based on my xml schema. It created a public partial class with DebuggerStepThroughAttribute. Well, I created another partial class file for this class to write my custom code and want to be able to step-into this code I've written but it appears the debugger is applying the step-through attribute to my partial class as well. Is there an easy way for me to step-into my code without manually removing the attribute each time I re-generate the partial
