TimerJob共享点服务器2013

Question

在sharepoint中，所有具有Status列（数据类型为Dropdown）和Duedate列的列表。 应更改的到期日期列今天的状态列应使用Timerjob自动关闭。我使用了此代码，但无法正常工作，请有人修改此代码以及如何实现此解决方案。

class.cs

namespace TimerJobNew
{
    class StatusCompleted : SPJobDefinition

    {
         public const string jobName = "CompletedProjectsJob";
        public StatusCompleted() : base() { }
        public StatusCompleted(SPWebApplication webApplication)
            : base(jobName, webApplication, null,SPJobLockType.Job)
        {
            Title = "Completed Projects Job";
        }
        public override void Execute(Guid targetInstanceId)
        {
            SPWebApplication webApp = this.Parent as SPWebApplication;
            SPSite site = new SPSite(SPContext.Current.Web.Url);
            SPWeb web = site.RootWeb;
           // SPWeb web = webApp.Sites["/sites/test"].RootWeb;
            SPList list = web.Lists.TryGetList("CommonList");
            SPListItem items;
            bool flag =true;
            SPListItemCollection itemColl = list.Items;
            var query =new SPSiteDataQuery();
            query.Lists = "<Lists BaseType='0' />";
            query.ViewFields = "<FieldRef Name='Title' Nullable='TRUE' />" +
                               "<FieldRef Name='Status' Nullable='TRUE' />" +
                               "<FieldRef Name='CommonlistID' Nullable='TRUE' />";

            query.Query = "<Where>" +
                                "<Eq>" +
                                    "<FieldRef Name='Status' />" +

                           "</Where>";
            query.Webs = "<Webs Scope='SiteCollection' />";
            DataTable dt = web.GetSiteData(query);
            foreach (DataRow row in dt.Rows)
            {
                items = list.Items.Add();
                if (itemColl.Count != 0)
                {
                    foreach (SPListItem item in itemColl)
                    {
                        if (item["CommonlistID"].ToString() == row["CommonlistID"].ToString())
                        {
                            flag = false;

Answer 1

如评论所述，由于使用SPTimerJob时SPContext为null，因此您的代码将永远无法工作。 （请注意，EventReceiver也是一样的）

您可以增强作业的构造函数以检索更多信息。 因此，您可以这样做：

public StatusCompleted(SPWebApplication webApplication, string TargetSite)
        : base(jobName, webApplication, null,SPJobLockType.Job)
{
    Title = "Completed Projects Job";
    Properties.Add("TargetSite", TargetSite);
}

然后，当您调用Execute（）方法时，您可以检索该站点：

string targetList = (this.Properties["TargetList"] ?? string.Empty).ToString();
using (SPSite site = new SPSite(targetSite))
{
   using (SPWeb web = site.OpenWeb())
   {
   //TO DO
   }
}

希望这可以帮助

最后，不要忘记调试TimerJob。 查找错误将非常有用。 您只需要将Visual Studio附加到进程OWSTIMER.exe。
