[英]Wpf ComboBox throws exception on combobox in windows 7
我在Windows 8上制作了WPF应用程序(框架4.5),该应用程序使用常规的组合框和一些其他控件。 我面临的问题是它在Windows 7上崩溃:
A first chance exception of type System.Windows.Markup.XamlParseException occurred in PresentationFramework.dll
Additional information: 'Initialization of 'System.Windows.Controls.ComboBox' threw an exception.'
这是我的组合框XAML:
<ComboBox Name="bloodGroupList" Grid.Row="7" Grid.Column="1"
SelectedIndex="{Binding Patient.BloodGroup, Converter={StaticResource StrToBlood}, Mode=TwoWay}"
IsEnabled="{Binding IsEditing}"
VerticalAlignment="Center" Margin="5,5.5" VerticalContentAlignment="Center"
BorderThickness="0" Height="22" TabIndex="4" HorizontalContentAlignment="Stretch">
<ComboBoxItem Content="A+" />
<ComboBoxItem Content="A-" />
<ComboBoxItem Content="B+" />
<ComboBoxItem Content="B-" />
<ComboBoxItem Content="O+" />
<ComboBoxItem Content="O-" />
<ComboBoxItem Content="AB+" />
<ComboBoxItem Content="AB-" />
</ComboBox>
我在某个博客上阅读了有关运行此修复程序NDP45-KB2750147-x64
但它说:
软件更新KB2750147安装向导不适用,或者被计算机上的其他状况所阻止。 请单击下面的链接以获取更多详细信息。
我将其放在App.xaml.cs
文件中以获取完整的堆栈跟踪。 这可能是解决问题的有用方法。
using System;
using System.Diagnostics;
using System.IO;
using System.Windows;
using System.Windows.Threading;
public partial class App : Application
{
void App_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
{
// All unhandled exceptions come here. A stacktrace is saved as a text file with date and time.
StackTrace st = new StackTrace(e.Exception);
string fileName = DateTime.Now.ToString().Replace('/', '-').Replace(':', '-') + " errors.txt";
fileName = @"C:\Users\Public\" + fileName;
System.Windows.MessageBox.Show("Critical Error. Closing program.\nStacktrace can be found:" + fileName);
using (var stream = new FileStream(fileName, FileMode.OpenOrCreate))
{
using (var strWrite = new StreamWriter(stream))
{
strWrite.Write(st.ToString());
}
}
if (MainWindow != null)
{
MainWindow.Close();
}
else
{
Environment.Exit(0);
}
e.Handled = true;
}
}
