In a WPF application, you can create XmlnsDefinitions to map multiple namespaces from another assembly into one reference . You can take advantage of that to map your own namespaces to the Microsoft default XmlnsDefinition, for example: [assembly: XmlnsDefinition("http://schemas.microsoft.com/winfx/2006/xaml/presentation", "MyLibrary.MyControls")] This way, you don't even need to add a re
在WPF应用程序中,您可以创建XmlnsDefinitions以将另一个程序集中的多个名称空间映射到一个引用中。 您可以利用它将您自己的名称空间映射到Microsoft默认的XmlnsDefinition,例如: [assembly: XmlnsDefinition("http://schemas.microsoft.com/winfx/2006/xaml/presentation", "MyLibrary.MyControls")] 这样,您甚至不需要在XAML文件中添加对命名空间的引用,因为它们已映射到默认的“xmlns”。 所以,如果我有一个名为“MyC
I'm making a windows 10 universal application whit the MVVM patern.

I would like to be able to use this color picker in my application: http://wpftoolkit.codeplex.com/wikipage?title=ColorPicker&referringTitle=Documentation I'm using Visual Studio 2010 Ultimate with .NET 4 installed. I'm coding in C# and WPF (XAML). What I've done so far: Downloaded and unzipped WPFToolkit.Extended.dll Added a reference to it in Visual Studio (can I veri
我希望能够在我的应用程序中使用这个颜色选择器: http://wpftoolkit.codeplex.com/wikipage?title=ColorPicker&referringTitle=Documentation 我使用安装了.NET 4的Visual Studio 2010 Ultimate。 我使用C#和WPF(XAML)编码。 到目前为止我所做的: 下载并解压WPFToolkit.Extended.dll 在Visual Studio中添加了对它的引用(我可以以某种方式验证它吗?) 将此行添加到MainWindow.xaml.cs中:using Xceed.Wpf
I have question about using XAML across the WPF and Silverlight platforms. Background: I have a silverlight app that needs to pass the Xaml to WPF and do some calculation to update the XAML. When I run the changes in WPF, I parse the XAML and convert it to the Canvas object which does the job perfectly fine. The problem is WPF strip out the silverlight namespace and even delete the name of
我有关于在WPF和Silverlight平台上使用XAML的问题。 背景: 我有一个Silverlight应用程序需要将Xaml传递给WPF,并执行一些计算来更新XAML。 当我在WPF中运行更改时,我解析XAML并将其转换为Canvas对象,该工作完美无瑕。 问题是WPF去掉了silverlight命名空间,甚至删除了一些元素的名称。 我用来将XAML转换为Canvas的代码 Canvas canvas = XamlReader.Parse(xaml) as Canvas 这里是Silverlight的原始Xaml: <Canvas
I have a WPF project defined like this: MyApp.sln MyAppWPF MyApp.Domain In one of my xaml files in the MyAppWPF project I'm trying to reference a class defined in MyApp.Domain project. I have a project reference in MyAppWPF to MyApp.Domain. I am trying to create the reference like this: <Window x:Class="MyAppWPF.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/pr
我有一个像这样定义的WPF项目: MyApp.sln MyAppWPF MyApp.Domain 在MyAppWPF项目中的一个xaml文件中,我试图引用MyApp.Domain项目中定义的类。 MyAppWPF中有一个项目引用 MyApp.Domain。 我试图创建这样的参考: <Window x:Class="MyAppWPF.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-na
We have a big wcf service, and a big xsd document where we have several elements and complex types. We generate code with the xsd.exe, and use the XmlSerializerFormat on our ServiceContract for the WCF service to serialize these objects again. Now we have a problem with xsd.exe and the definitions of an array of strings. Image we have the following element defined.. <xs:element name="Con
我们有一个很大的wcf服务,还有一个很大的xsd文档,我们有几个元素和复杂的类型。 我们使用xsd.exe生成代码,并使用WCF服务的ServiceContract上的XmlSerializerFormat来再次序列化这些对象。 现在我们遇到了xsd.exe和字符串数组的定义问题。 图像我们有以下元素定义.. <xs:element name="Configuration" type="Configuration"/> <xs:complexType name="Configuration"> <xs:sequence> <xs:ele
Let's suppose if we have a class like class Person { internal int PersonID; internal string car ; } Now I have a list of this class: List<Person> persons; Now this list can have multiple instances with same PersonIDs, for example: persons[0] = new Person { PersonID = 1, car = "Ferrari" }; persons[1] = new Person { PersonID = 1, car = "BMW" }; persons[2] = new Pers
假设我们有类似的课程 class Person { internal int PersonID; internal string car ; } 现在我有这个类的列表: List<Person> persons; 现在这个列表可以有多个具有相同PersonID的实例,例如: persons[0] = new Person { PersonID = 1, car = "Ferrari" }; persons[1] = new Person { PersonID = 1, car = "BMW" }; persons[2] = new Person { PersonID = 2, car = "Audi" }; 有没有一种方
I've searched around and haven't really found a clear answer as to when you'd want to use .First and when you'd want to use .FirstOrDefault with LINQ. When would you want to use .First ? Only when you'd want to catch the exception if no results where returned? var result = List.Where(x => x == "foo").First(); And when would you want to use .FirstOrDefault ? When you
我已经四处搜索,并且还没有真正找到明确的答案,以便何时使用.First以及何时想要使用带有LINQ的.FirstOrDefault 。 你想什么时候使用.First ? 只有当你想要捕捉异常,如果返回没有结果? var result = List.Where(x => x == "foo").First(); 你想什么时候使用.FirstOrDefault ? 如果你总是想要默认类型,如果没有结果? var result = List.Where(x => x == "foo").FirstOrDefault(); 就此而言,Take呢? var re
I use LINQ to Objects instructions on an ordered array. Which operations shouldn't I do to be sure the order of the array is not changed? I examined the methods of System.Linq.Enumerable, discarding any that returned non-IEnumerable results. I checked the remarks of each to determine how the order of the result would differ from order of the source. Preserves Order Absolutely. You can
我在有序数组上使用LINQ to Objects指令。 我应该做哪些操作来确保数组的顺序没有改变? 我检查了System.Linq.Enumerable的方法,放弃了返回非IEnumerable结果的任何方法。 我检查了每一个的评论,以确定结果的顺序将如何与来源的顺序不同。 完全保留订单。 您可以通过索引将源元素映射到结果元素 AsEnumerable 投 CONCAT 选择 ToArray的 ToList 保留订单。 元素被过滤,但不被重新排序。 不同 除
I found an example in the VS2008 Examples for Dynamic LINQ that allows you to use a sql-like string (eg OrderBy("Name, Age DESC")) for ordering. Unfortunately, the method included only works on IQueryable<T> ;. Is there any way to get this functionality on IEnumerable<T> ? Just stumbled into this oldie... To do this without the dynamic LINQ library, you just need the c
我在VS2008动态LINQ示例中找到了一个示例,它允许您使用类似sql的字符串(例如OrderBy("Name, Age DESC"))进行排序。 不幸的是,这个方法仅适用于IQueryable<T> 有没有什么办法可以在IEnumerable<T>上获得这个功能? 刚刚偶然发现这位老人...... 要做到这一点没有动态的LINQ库,你只需要下面的代码。 这涵盖了最常见的场景,包括嵌套属性。 为了使它与IEnumerable<T>一起工作,你可以添加
