System.Windows.Baml2006.TypeConverterMarkupExtension“关于提供价值'引发了异常。” [英] 'Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.'

问题描述

当我打开WPF窗口标题中抛出异常，奇怪的是，这不会发生在我的Windows 7开发计算机上，也当它被部署在Windows 7中它发生了。

The exception in the title is thrown when I open a window in WPF, the strange thing is that this does not happen on my Windows 7 development machine nor does it happen when it is deployed on Windows 7.

我只得到在Windows XP的这个错误，并且只有我打开窗户的第二次。

I only get this error on Windows XP, and only the second time that I open the window.

下面是代码在打开的窗口：

Here is the code to open the window:

ReportParametersWindow win = null;

      bool canOverWrite = _shownReports.Contains(rpt.FriendlyName);

      if (!(canOverWrite))
        win = new ReportParametersWindow(rpt.FriendlyName, rpt.ReportParameters, canOverWrite);
      else
        win = new ReportParametersWindow(rpt.FriendlyName, (container.ParametersWindow as ReportParametersWindow).Controls, canOverWrite);

      win.ShowDialog();

和XAML中的窗口：

<Window xmlns:my="clr-namespace:MHA.Modules.Core.Controls;assembly=MHA.Modules.Core"  
    x:Class="MHA.Modules.Reports.Views.ReportParametersWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Parameters" Height="500" Width="600" MinWidth="500" MaxHeight="500" 
    Icon="/MHA.Modules.Reports;component/Images/Parameters.ico" SizeToContent="WidthAndHeight" 
    WindowStartupLocation="CenterScreen"
    xmlns:odc="clr-namespace:Odyssey.Controls;assembly=Odyssey" Closed="Window_Closed">

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="40"/>
    </Grid.RowDefinitions>
    <ScrollViewer Grid.Row="0" Name="ScrollViewer1" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" CanContentScroll="True">
        <StackPanel Name="ParameterStack">
            <my:LocationCtl Text="Parameters for report - " Name="loc"/>
        </StackPanel>
    </ScrollViewer>
    <Grid Grid.Row="1">
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>

        <CheckBox ToolTip="This will replace the first report of the same type that was shown." Name="chkOverwrite" Content="Overwrite old" VerticalAlignment="Center" Margin="5,0"></CheckBox>

        <Button Grid.Column="2" HorizontalAlignment="Right" Margin="5,0" Height="30" Style="{StaticResource DionysusButton}" Width="100" IsDefault="True" Click="Button_Click">
            <StackPanel Orientation="Horizontal">
                <Image Source="/MHA.Modules.Reports;component/Images/Success.png"></Image>
                <TextBlock Margin="5,0" Text="Accept" VerticalAlignment="Center"></TextBlock>
            </StackPanel>
        </Button>
    </Grid>
</Grid>

有没有人有什么建议？

推荐答案

该解决方案是一个相当奇怪的一个，但我有它想通了。

The solution is quite a weird one but I have it figured out.

我认识到错误是在窗口在InitializeComponent（）发生，我再补充一个尝试捕捉到构造和表现异常的的InnerException。

I realized that the error was occurring on the InitializeComponent() of the window, I then added a try catch to the constructor and showed the InnerException of the Exception.

这是我收到的错误是图像格式无法识别。

The error that I received is "Image format not recognized".

我不知道为什么会这样只有在Windows XP，并且显示在窗口中的第二次，但通过与.png格式问题得到解决更换我的.ICO。

I have no idea why this happens only on XP and the second time that the window is shown but by replacing my .ico with a .png the problem was resolved.

希望这可以帮助别人。
