当我IReadOnlyList在我的代码中实现时,我的单元测试抛出了一个AutoMapperMappingException.

从挖掘文章和文档,我的猜测是AutoMapper需要特殊的readonly类型编码.这会是什么样的？

注意:我尝试Mapper.AssertConfigurationIsValid();了另一篇文章建议,但没有改进.

我正在访问EWS日历中的约会与会者.我试过了:

cView.PropertySet = new PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End);

但是我的appointments列表条目每个都返回null必需/可选参加者字段,即使多个用户已接受测试约会.我的假设是PropertySet需要包含更多ApplicationSchema属性,如下所示:

cView.PropertySet = new PropertySet(AppointmentSchema.Subject,
                AppointmentSchema.Start,
                AppointmentSchema.End,
                AppointmentSchema.RequiredAttendees,
                AppointmentSchema.OptionalAttendees);

但是,这会在calendar.FindAppointments(cView)上引发以下ServiceValidationException错误:

Microsoft.Exchange.WebServices.Data.ServiceValidationException: 无法在FindItem请求中使用属性RequiredAttendees.

如何修复此问题以appointments包括必需/可选的与会者？

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);

service.Credentials = new WebCredentials(emailAddress, emailPassword);        

// Initialize values for the start and end times, and the number of appointments to retrieve.
DateTime startDate = DateTime.Now;
DateTime endDate = startDate.AddYears(1);
const int NUM_APPTS = 4;

// Initialize the calendar folder object with only the folder ID. 
CalendarFolder calendar = CalendarFolder.Bind(service, …

我想要 按钮上的背景图像出现在右上角.

我成功background-position: bottom top 100px地将图像移动到顶部,但是我没有成功将图像向右移动.

是否有类似的东西background-position: bottom top 100px, right 900px可能有助于产生预期的结果？

#AddNewMeetingButton {
    position: absolute;
    top: 0;
    text-align: center;
    background-image: url(Images/add_icon_48x48.png);
    background-position: bottom top 100px, right 800px;
    background-repeat: no-repeat;
    height: 190px;
    width: 915px;
    background-color: transparent;
    outline: none;
    border: none;
    z-index: 2;

我写了一个简单的Python函数来生成matplotlib图.我plotData从一个单独的脚本中多次调用,但每次生成一个新的图.我想要的是总是只有一个情节,比如subplot.clear()清除数据变化之间的子图.

我需要一种从外部识别图形的方法,plotData以便我可以清除新数据的图形.实现这一目标的最佳方法是什么？

## Plot Data Function
def plotData(self):

        # Setup figure to hold subplots
        f = Figure(figsize=(10,8), dpi=100)

        # Setup subplots
        subplot1=f.add_subplot(2,1,1)
        subplot2=f.add_subplot(2,1,2)

        # Show plots
        dataPlot = FigureCanvasTkAgg(f, master=app)
        dataPlot.show()
        dataPlot.get_tk_widget().pack(side=RIGHT, fill=BOTH, expand=1)
