我最终将创建一个共享点日历。我想在这里创建一个事件列表,但我会在这里得到这个奇怪的错误。
我创建了一个事件列表,然后检查[查看]它是否已经创建。如果是,我不想创建它,但我的 testLabel 说它已经存在。
当我尝试删除列表时myButton_Click
,它给了我这个错误:
Microsoft.SharePoint.Client.ServerException:URL 为“ http://server1 ”的站点中不存在列表“CompanyCalendar ”。
代码
using Microsoft.SharePoint.Client;
namespace CalendarWeb.Pages
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Uri hostWeb = new Uri(Request.QueryString["SPHostUrl"]);
using (var clientContext = TokenHelper.GetS2SClientContextWithWindowsIdentity(hostWeb, Request.LogonUserIdentity))
{
Web web = clientContext.Web;
ListCreationInformation listCreator = new ListCreationInformation();
listCreator.Title = "CompanyCalendar";
listCreator.Description = "Workcalendar";
listCreator.TemplateType = (int)ListTemplateType.Events;
var ifListExcists = web.Lists.GetByTitle(listCreator.Title);
if (ifListExcists == null)
{
web.Lists.Add(listCreator);
clientContext.ExecuteQuery();
testLabel.Text = "The " + listCreator.Title + " list was created";
}
else
{
testLabel.Text = "List already excist";
}
}
}
protected void myButton_Click(object sender, EventArgs e)
{
Uri hostWeb = new Uri(Request.QueryString["SPHostUrl"]);
using (var clientContext = TokenHelper.GetS2SClientContextWithWindowsIdentity(hostWeb, Request.LogonUserIdentity))
{
Web web = clientContext.Web;
var deleteList = web.Lists.GetByTitle("CompanyCalendar");
deleteList.DeleteObject();
clientContext.ExecuteQuery();
testLabel.Text = "list deleted";
}
}
}
}
当我查看我的 server1 站点时,该列表不存在,但在代码中它似乎存在,因为我的变量"ifListExcists"
永远不会为空。
