这是一个跟进问题:linq issue with creating relationships关于我收到的答案。我不确定发生了什么,但我收到了一个错误:
The underlying connection was closed: An unexpected error occurred on a receive.
这就是异常发生的地方:
string uriGroup = "http://localhost:8000/Service/Group";
private void ListGroups_Click(object sender, RoutedEventArgs e)
{
XDocument xDoc = XDocument.Load(uriGroup); // this line
var groups = xDoc.Descendants("Group")
.Select(n => new
{
GroupName = n.Element("GroupName").Value,
GroupHeader = n.Element("GroupHeader").Value,
TimeCreated = DateTime.Parse(n.Element("TimeAdded").Value),
Tags = n.Element("Tags").Value,
Messages = n.Element("GroupMessages").Value
})
.ToList();
dataGrid2.ItemsSource = groups;
}

由于您要返回List
个对象,因此您可能已超过MaxItemsInObjectGraph。您可以通过修改web.config(或app.config)来增加该值:
<behaviors>
<behavior>
<dataContractSerializer maxItemsInObjectGraph="6553600" />
</behavior>
</behaviors>
您可能还想考虑一下常见的嫌疑人:

值您应该启用WCF Tracing,因为它会包含更详细的错误。是的,这适用于自托管应用程序。
