我有一个WCF服务.
正常操作会看到服务器正在进行一些处理,通过回调将填充的XactTaskIn对象返回给客户端.我有这个工作正常.
我的问题是,当我尝试将returnData变量设置为填充的XactException并尝试通过回调将XactTaskIn发送回客户端时,我会抛出以下异常.
异常 - 不要求"数据协定名称为'XactException:http://schemas.datacontract.org/2004/07/'的类型'XactException'.请考虑使用DataContractResolver或将已知类型静态未知的任何类型添加到已知类型列表中 - 例如,通过使用KnownTypeAttribute属性或将它们添加到传递给DataContractSerializer的已知类型列表中." (System.Runtime.Serialization.SerializationException)异常消息="类型'XactException',数据协定名称为'XactException:http://schemas.datacontract.org/2004/07/'不是预期的.考虑使用DataContractResolver或添加任何静态地知道已知类型列表的类型 - 例如,通过使用KnownTypeAttribute属性或将它们添加到传递给DataContractSerializer的已知类型列表.",Exception Type ="System.Runtime.Serialization.SerializationException"

我希望能够设置一个包含2列的网格,第一列占用可用空间的20%,第二列占80%.在xaml中我会使用*运算符,但我无法解决如何以编程方式执行此操作.
在Xaml我会这样做:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition width="20*" />
<ColumnDefinition width="80*" />
</Grid>
在我想要的代码中:
Grid grid = new Grid();
grid.ColumnDefinitions.Add( new ColumnDefinition(20*) );
grid.ColumnDefinitions.Add( new ColumnDefinition(80*) );
请有人建议.
使用Windows安装程序部署程序时,如何设置默认安装路径.
我有一个作为WPF应用程序的ac #project,但我现在想把它构建为一个dll.我以前通过从项目中删除app.xaml并将其构建类型设置为dll来完成此操作.
我现在的问题是app.xaml包含一些xaml来实例化应用程序变量.为了解决这个问题,我试图以编程方式在将要调用的第一个xaml窗口中设置这些应用程序变量.
我试图在代码中模拟的xaml是:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/Styles/Shared.xaml"/>
<ResourceDictionary Source="Resources/Styles/ToolBar.xaml"/>
<ResourceDictionary Source="Resources/Styles/GroupBox.xaml"/>
<ResourceDictionary Source="Resources/Styles/ZoomBox.xaml"/>
<ResourceDictionary Source="Resources/Styles/ScrollBar.xaml"/>
<ResourceDictionary Source="Resources/Styles/Expander.xaml"/>
<ResourceDictionary Source="Resources/ApplicationToolbar.xaml"/>
<ResourceDictionary Source="Resources/DesignerItem.xaml"/>
<ResourceDictionary Source="Resources/Styles/ToolboxItem.xaml"/>
<ResourceDictionary Source="Resources/Styles/Toolbox.xaml"/>
<ResourceDictionary Source="Resources/Connection.xaml"/>
<ResourceDictionary Source="Resources/Slider.xaml"/>
<ResourceDictionary Source="Resources/ScrollViewer.xaml"/>
<ResourceDictionary Source="Resources/StatusBar.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
这是我的代码:
ResourceDictionary myResourceDictionary = new ResourceDictionary();
myResourceDictionary.Source = new Uri("C:\\Resources\\Styles\\Shared.xaml");
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
myResourceDictionary.Source = new Uri("C:\\Resources\\Styles\\ToolBar.xaml");
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
myResourceDictionary.Source = new Uri("C:\\Resources\\Styles\\GroupBox.xaml");
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
myResourceDictionary.Source = new Uri("C:\\Resources\\Styles\\ZoomBox.xaml");
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
myResourceDictionary.Source = new Uri("C:\\Resources\\Styles\\ScrollBar.xaml");
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
myResourceDictionary.Source = new Uri("C:\\Resources\\Styles\\Expander.xaml");
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
myResourceDictionary.Source = new Uri("C:\\Resources\\ApplicationToolbar.xaml");
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);

我有一个使用MEF加载插件的程序.我希望系统的客户端和服务器部分能够使用将位于服务器上的相同插件存储.
我的问题是,当我将插件位置设置为" C:\Users\Administrator\Desktop\ClientPlugins"时插件加载正常.如果我将位置更改为" \\XRP-SERVER\Users\Administrator\Desktop\ClientPlugins",则不会加载插件.
当我\\XRP-SERVER\Users\Administrator\Desktop\ClientPlugins在Windows资源管理器中输入" "时,找到位置并且插件dll就在那里.
请有人帮忙.
如果您需要更多信息,请与我们联系.

我知道这已经有很多东西已经尝试了一些东西,但没有运气来修复它.
我有一个C#程序,它构建了一个XML文档,我试图将它保存到MyDocuments中的文件夹.调用XMLDoc.Save函数时,我得到了以下异常.
访问路径'C:\ Users\Ash\Documents\ConfigOutput'被拒绝
我有视觉工作室作为管理员运行.有关如何解决它的任何想法？
我已经尝试保存到桌面和C:\文件夹中.
我正在使用Windows 7.
运行构建的可执行文件似乎也不起作用.
抱歉,我觉得自己很愚蠢.我确实没有在输出路径中添加文件名.我不会删除任何其他人通过这个问题完成的问题!感谢所有的帮助/评论.
