我正在编写两个依赖项属性,并且我在VS11的设计窗口中不断收到"[Property]已经由'FrameworkElement'注册"错误.这是我的代码片段

        public static readonly DependencyProperty IsEditingNumberProperty =
        DependencyProperty.Register("IsEditingNumbers", typeof(bool), typeof(FrameworkElement),
        new FrameworkPropertyMetadata(true, FrameworkPropertyMetadataOptions.AffectsRender));

问题似乎是第3个参数(所有者参数typeof(FrameworkElement)).如果我将第3个参数设置为包含两个依赖项属性的类,则错误消失,但我不能直接使用xaml中的属性.在使用之前,我必须为每个依赖属性添加所有权.

实际上,它确实正确渲染,但只有当我第一次打开它时.第一次渲染后,它会立即给我一个例外.在运行时,它似乎完美地工作.

我做错了什么,有没有办法摆脱这个恼人的错误？

这是我的自定义类(包括2个依赖属性):

public partial class EditableTextBox : UserControl
{
    #region Dependency Properties
    public static readonly DependencyProperty IsEditingNumberProperty =
        DependencyProperty.Register("IsEditingNumber", typeof(bool), typeof(FrameworkElement),
        new FrameworkPropertyMetadata(true, FrameworkPropertyMetadataOptions.AffectsRender));

    public static readonly DependencyProperty TextProperty =
        DependencyProperty.Register("Text", typeof(string), typeof(FrameworkElement),
        new FrameworkPropertyMetadata("0", FrameworkPropertyMetadataOptions.AffectsRender) 
        { 
            CoerceValueCallback = new CoerceValueCallback((sender,value) =>
                {
                    return expressionRestaraint.Match((string)value).Value;
                })
        });
    #endregion

    public static Regex expressionRestaraint = new Regex("[-a-zA-z0-9+*.\\(\\)\\[\\]\\{\\}]*");

    public string Text
    {
        get { (string)GetValue(TextProperty); }
        set …

这是一个CLR项目.我正在导入两个具有相同名称的DLL文件quizz.dll(我将旧版本重命名为legacyquizz.dll),并将较新版本包含在quizz.dll旧版转换器测试项目中.(正在测试的旧版转换器项目只导入旧的quizz.dll).

这是我得到的错误...

已导入具有相同简单名称"Quizz,Version = 2.0.0.1,Culture = neutral,PublicKeyToken = null"的程序集.

尝试删除其中一个引用或签名以并排启用.C:\ ...\ Quizz.dll

它指向的路径是较新版本的quizz.dll的目标.

我在legacyquizz.dll文件上使用外部别名:

extern alias legacy;

在这种情况下,什么是"简单名称"？

我正在尝试将我编译的Web应用程序上传到Internet.有人告诉我,我需要的是应该进入bin文件夹的dll文件？这是真的还是我需要上传dll文件和bin文件夹？

另外,是否有更好的构建方法,以便我不必将我的图像,CSS等混合到我的项目文件夹中？也许一种方法将dll文件复制到bin文件夹和我所有的aspx页面？

我让它工作,但似乎我一直在复制一堆文件,我知道最终会出现一些问题.

运行 bundle install 时出现此错误：

如何使图标大小与angular2中字体的相对大小一起使用？

我在嵌套循环中调用异步函数,如下所示

var queue = new Queue<ExchangeEmailInformation>(mailInformation);
var currentQueue = queue.ToList();
foreach (var exchangeEmailInformation in currentQueue)
{
    ExchangeEmailInformation information = exchangeEmailInformation;
    foreach (var queueList in exchangeEmailInformation.Attachment)
    {
        Attachment attachment = queueList;
        information.FileName = attachment.Name;
        var emailId = information.Sender.Split('@');
        information.UserAlias = emailId[0];
        information.FileSize = attachment.Size;
        AddAttachmentAsync(information);

    }

}

private static void AddAttachmentAsync(ExchangeEmailInformation information)
{
    System.Threading.Tasks.Task.Factory.StartNew(
        () =>
        AddAttachment(information.UserAlias, information.EngagementName,
                        information.DocumentTransferId.ToString(), information.FileName,
                        information.FileSize.ToString(), information.ActivityName)).ContinueWith(
                            task => OnComplete(task, information), TaskContinuationOptions.None);
}

static void AddAttachment(string userAlias, string engagementName, string documentTranferId, string fileName, string fileSize,string activityName) …
