<UserControl x:Class="TestImageSource.UserControl1"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"               xmlns:d="http://schemas.microsoft.com/expression/blend/2008"               mc:Ignorable="d"               d:DesignHeight="300" d:DesignWidth="300">     <Grid>         <Image Source="TestImageSource;component/Images/laugh.gif" />     </Grid> </UserControl>

控件2：

<UserControl x:Class="TestImageSource.UserControl2"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"               xmlns:d="http://schemas.microsoft.com/expression/blend/2008"               mc:Ignorable="d"               d:DesignHeight="300" d:DesignWidth="300">     <Grid>         <Image Source="/TestImageSource;component/Images/laugh.gif" />     </Grid> </UserControl>

调用该控件：

<Window x:Class="TestImageSource.MainWindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         Title="MainWindow" Height="520" Width="1022" xmlns:my="clr-namespace:TestImageSource">     <Grid>         <my:UserControl1 HorizontalAlignment="Left" Margin="21,12,0,0" x:Name="userControl11" VerticalAlignment="Top" Height="267" Width="423" />         <my:UserControl2 HorizontalAlignment="Left" Margin="540,58,0,0" x:Name="userControl21" VerticalAlignment="Top" Height="320" Width="411" />     </Grid> </Window>

区别在于第一个控件的Source="TestImageSource;component/Images/laugh.gif" 是手动填写。第二个则是，属性-source-选择图片。
结果造成，作为控件使用时，控件1无法显示图片，控件2正常显示图片。如下：

不知是本地环境有问题还是原本如此，所以同样使用的需要注意了，还是手动选择图片吧。
