SharePoint 讨论板常见的代码操作

SharePoint 讨论板常见的代码操作

        我们直入主题，讨论针对SharePoint 讨论板常用的代码操作有哪些呢？
1. 你的网站集和网站：
 1
 2
SPSite currentSite = SPContext.Current.Site;
SPWeb currentRootWeb = currentSite.RootWeb;
来自CODE的代码片
SiteInstance.cs
2. 假设我们有一个名为“MyDiscussionList”的讨论板列表。
        获得这个列表的GUID：
 1
 2
 3
 4
 5
 6
 7
 8
 9
Guid myDiscussionListGUID = Guid.NewGuid();
foreach (SPList list in currentRootWeb.Lists)
{
if (list.BaseTemplate.ToString() == "DiscussionBoard" && list.Title == "MyDiscussionList")
{
myDiscussionListGUID = list.ID; // Read GUID of Discussion List
break;
}
}

GetGUID.cs
        小建议：
  • list.ItemCount将会返回所有讨论和答复。
  • list.Items.Count将只返回答复。
3. 获得你的列表：
 1
SPList myDiscussionList = currentRootWeb.Lists.GetList(myDiscussionListGUID, false);

SPListItem newItem = SPUtility.CreateNewDiscussion(myDiscussionList.Items, "New Message using code");
newItem["Body"] = "My new message content using code";
newItem.Update();

{
Response.Write("Attachment Url " + folder.Attachments.UrlPrefix + folder.Attachments + "<BR>");
