Question

我创建了一个控制台应用程序来添加/更新和删除SharePoint 365中的项目。它在两天前工作，现在我收到此错误：

string login = "username@web365.onmicrosoft.com";   
string password = "pooo%yup12"; //give your password  
var securePassword = new SecureString();
foreach (char c in password)
{
  securePassword.AppendChar(c);
}
string siteUrl = "https://web365.onmicrosoft.com/sites/test";
ClientContext clientContext = new ClientContext(siteUrl);

//Add New Item
//Create new object of List
List newlist = clientContext.Web.Lists.GetByTitle("Test");
ListItemCreationInformation itemInfo = new ListItemCreationInformation();
ListItem newItem = newlist.AddItem(itemInfo);
newItem["Title"] = "2";
newItem.Update();

var onlineCredentials = new SharePointOnlineCredentials(login, securePassword);
clientContext.Credentials = onlineCredentials;
clientContext.Load(clientContext.Web, w => w.Title);
clientContext.ExecuteQuery();

这是我的代码，我是从网上修改过来的。

<UserControl.Resources>

                            </DockPanel>
                        </Border>

            </Setter.Value>
        </Setter>
    </Style>

<ListView x:Name="SpecificationTablesUI" Style="{StaticResource OptionsListViewStyle}" 
        ItemsSource="{Binding Path=SpecTables}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <DockPanel LastChildFill="True">
                <Expander Header="{Binding TableName}" Style="{StaticResource StatusGroupExpander}">
                    <TextBlock Text="{Binding SelectedQuantity}"/>
                </Expander>
            </DockPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}" BasedOn="{StaticResource OptionsListViewItemStyle}">
            <Setter Property="Tag" Value="{Binding Path=DataContext, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListView}}"/>
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

我再次调试，我注意到clientContext正在抛出此异常 ServerVersion ='clientContext.ServerVersion'引发了类型'Microsoft.SharePoint.Client.PropertyOrFieldNotInitializedException'的异常

我在网上找到了一个解决方案，建议删除位于users文件夹下的appdata文件，我只是这样做了，错误就消失了。
