反序列化XML (TFS oData)
本文关键字：oData TFS XML 反序列化 | 更新日期: 2023-09-27 18:01:16
我正在开发一个windows 8.1应用程序，几天来我一直在努力解决一个问题。这是我的问题:
我有一个tfs项目，通过我的应用程序，我想跟随它(显示状态，由创建，由改变等)使用tfs odata。
这是获得的xml文件:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<feed xml:base="https://tfsodata.visualstudio.com/DefaultCollection/" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://www.w3.org/2005/Atom">

我的类:
粘贴特殊的XML类(来自上面的XML)
my function:
public IEnumerable<TfsEntitiesXml.feed> Deserialize()
{
string xml = "https://tfsodata.visualstudio.com/DefaultCollection/Projects('xxxx')/WorkItems".Trim();
XmlSerializer serilaizer = new XmlSerializer(typeof(TfsEntitiesXml.feed));
//string xml = "";
byte[] buffer = Encoding.UTF8.GetBytes(xml);
var stream = new MemoryStream();
stream.WriteAsync(buffer, 0, buffer.Length);
IEnumerable<TfsEntitiesXml.feed> result = (IEnumerable<TfsEntitiesXml.feed>)serilaizer.Deserialize(stream);
return result;
}
和xaml
<ListView x:Name="itemsListView"
SelectionMode="None"
ItemsSource="{Binding TfsList}" >
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock
Foreground=
"{StaticResource ListViewItemOverlayForegroundThemeBrush}"
Style="{StaticResource TitleTextStyle}" Height="60"
TextWrapping="Wrap"
Margin="15,5,15,0">
<Run Text="{Binding Title}" ></Run>
<Run Text="{Binding State}" ></Run>
</TextBlock>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
var projects = tfsConnector.Deserialize();
DefaultViewModel["TfsList"] = projects;
当我运行时，我得到这个异常
类型为'System '的异常。InvalidOperationException'在System.Xml.dll中发生，但未在用户代码中处理
附加信息:XML文档(0,0)中有错误。
我已经为这个问题挣扎了好几天了。有人能帮帮我吗?谢谢你
您应该简单地为tfsodata服务创建一个服务引用，这样您将获得一个类型化引用，而不必与xml混淆。
