我有以下控制器方法

    public ActionResult Export(string [,] data, string workbookName)
    {
        ExcelWorkbook workbook = new ExcelWorkbook();
        workbook.AddRows(data);

        return new FileStreamResult(workbook.SaveSheet(), "application/vnd.ms-excel")
        {
            FileDownloadName = workbookName
        };
    }

它采用二维数组并输出到工作表.

到目前为止,当从带有json数组的jquery发布时,我在data参数中获取除null之外的任何内容都失败了.有谁知道填充数据参数所需的正确json格式.我在Jquery 1.7.2上.

这是我的jquery

    var arguments = {};

    arguments.data = [["1"], ["2"], ["3"]];
    arguments.workbookName = "test";

    //Populate arrayOfValues 
    $.ajax({
        type: "POST",
        url: '/Excel/Export',
        datatype: "json",
        traditional: true,
        data: arguments,
        success: function (data) {
            alert(data);
        }
    });

我在C#中使用以下代码搜索LDAP以轮询用户的活动目录:

DirectoryEntry entry = new DirectoryEntry(ldapPath, userName, password);

DirectorySearcher Searcher = new DirectorySearcher(entry);

Searcher.CacheResults = true;
Searcher.SearchScope = SearchScope.Subtree;

Searcher.Filter = "(&(&(objectCategory=person)(objectClass=user))
    (|(samaccountname=" + userSearch.SamAccountName + "*)
    (&(GivenName=" + userSearch.FirstName + "*)(SN=" + userSearch.Surname + 
        "*))))";

Searcher.PropertiesToLoad.AddRange(new string[] {"DisplayName", "GivenName",
    "DistinguishedName","Title","manager",
         "mail", "physicalDeliveryOfficeName", "DirectReports", "Company", 
         "Description", "SAMAccountName"});

SearchResultCollection results = Searcher.FindAll();

List<ActiveUser> activeUsers = new List<ActiveUser>();

我使用输入参数userSearch.FirstName ="jo"和userSearch.LastName ="bl"运行它,并期望一个用户"Joe Bloggs",但这没有出现在结果列表中.如果我使用Windows中的Active Directory用户和计算机工具中的名称文本框尝试此操作,则Joe Bloggs将显示为列表中的唯一用户.我正在使用正确的LDAP路径.我使用错误的过滤器来复制Windows工具中的功能吗？显示名称上是否有"喜欢"搜索？

任何帮助,将不胜感激.

我知道这很长,但请耐心等待.

我使用MVVM光框架在MVVM光样本中创建了一个非常类似于Laurent Bugnion的"MyFriends"程序的Windows应用商店程序.

在他的程序中,他使用gridview的SelectedItem属性来跟踪哪个项目是所选项目.

问题是,我让用户能够在GridView上选择多个项目,然后使用App Bar上的按钮对它们进行操作.对于此SelectedItem将无法正常工作.

有谁知道如何使用多选GridView进行此工作？我已经根据WPF上的一些文章尝试了GridViewItem的IsSelected属性,但这似乎不起作用.SelectedTimesheets getter在调用时总是返回空.这是我到目前为止:

MainPage.xaml(绑定到带有子TimesheetViewModel可观察集合的MainViewModel):

<GridView 
    x:Name="itemGridView"
    IsItemClickEnabled="True"
    ItemsSource="{Binding Timesheets}"
    ItemTemplate="{StaticResource TimesheetTemplate}" 
    Margin="10"
    Grid.Column="0"
    SelectionMode="Multiple"
    helpers:ItemClickCommand.Command="{Binding NavigateTimesheetCommand}" RenderTransformOrigin="0.738,0.55"  >
    <GridView.ItemContainerStyle>
        <Style TargetType="GridViewItem">
            <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/>
        </Style>
    </GridView.ItemContainerStyle>

</GridView>

MainViewModel(从完整代码中删除):

public class MainViewModel : ViewModelBase
{
    private readonly IDataService _dataService;
    private readonly INavigationService _navigationService;

    /// <summary>
    /// Initializes a new instance of the MainViewModel class.
    /// </summary>
    public MainViewModel(IDataService dataService, INavigationService navigationService)
    {
        _dataService = dataService;
        _navigationService = navigationService;

        Timesheets = new ObservableCollection<TimesheetViewModel>();
        ExecuteRefreshCommand();

    } …
