问题描述

我是WPF和XAML的完全新手，但我已经很遗憾首先尝试学习它.我不确定为什么在运行下面的代码时出错，我直接从WPF 4发布的书中直接复制了它.如果你们中的任何一个可以帮助我解决这个问题，我们将欠你们一个大忙:

I am complete newbie to WPF and XAML and I am already regretting trying to learn it in the first place. I am not sure why the error in running the code below, I copied it directly from a WPF 4 unleashed book. If any of you guys can help me in figuring this our I will owe you guys a big favor:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:System="clr-namespace:System;assembly=mscorlib"
        xmlns:collections="clr-namespace:System.Collections;assembly=mscorlib"
        xmlns:Person="clr-namespace:Src"
        Title="MainWindow" Height="354" Width="525">
  <StackPanel>
    <Label Name="lblText" Foreground="BlanchedAlmond" FontWeight="Bold" FontSize="20">
      Test
    </Label>
    <Label x:FactoryMethod="System:Guid.NewGuid">Test2</Label>
    <ListBox SelectionChanged="ListBox_SelectionChanged">
      <Person:Person FirstName="Deepak" LastName="Sharma"></Person:Person>
      <Person:Person FirstName="Nidhi" LastName="Sharma"></Person:Person>
    </ListBox>
  </StackPanel>
</Window>

推荐答案

x:FactoryMethod 是 XAML 2009功能，根据文档，标记编译的XAML不支持该文件.

x:FactoryMethod is a XAML 2009 feature, which according to the documentation are not supported in markup compiled XAML.

此外， Guid.NewGuid 不会返回 Label ，因此我不确定这应该如何解决.

Besides that Guid.NewGuid does not return a Label so i am not sure how this is supposed to work out in the first place.
