Winforms数据表的代码 - 什么是WPF等价物?

我在Winforms应用程序中有以下代码,它按预期工作:

private void btnFetchCollections_Click(object sender, EventArgs e)
{
    try
    {
        var scDal = new SiteCollectionDal();
        var dt = new DataTable();

        List<SiteCollectionEntity> siteCollections = scDal.FetchSiteCollections();

        dt.Columns.Add(new DataColumn("Site Name", typeof(string)));

        foreach (SiteCollectionEntity siteCollectionEntity in siteCollections)
        {
            DataRow row = dt.NewRow();

            row["Site Name"] = siteCollectionEntity.Url;

            dt.Rows.Add(row);

            dt.AcceptChanges();
        }

        dataSiteCollections.DataSource = dt;

    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

我现在正在为这个项目构建一个新的WPF接口,以下内容不起作用 - 我应该如何接近它?

private void btnFetchSiteCollections_Click(object sender, RoutedEventArgs e)
{
    try
    {
        var scDal = new SiteCollectionDal();
        var dt = new DataTable();

        List<SiteCollectionEntity> siteCollections = scDal.FetchSiteCollections();

        dt.Columns.Add(new DataColumn("Site Name", typeof(string)));

        foreach (SiteCollectionEntity siteCollectionEntity in siteCollections)
        {
            DataRow row = dt.NewRow();

            row["Site Name"] = siteCollectionEntity.Url;

            dt.Rows.Add(row);

            dt.AcceptChanges();
        }

        dataSiteCollections.ItemsSource = dt;

    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

我收到的错误在以下一行:

dataSiteCollections.ItemsSource = dt;

这是:

  

无法将源类型'System.Data.DataTable'转换为目标类型   'System.Collections.IEnumerable'

答案 0 :(得分:1)

试试这个:

dataSiteCollections.ItemsSource = dt.AsDataView();
