MOSS对列表的部分操作
1.查询列表的所有字段
view plaincopy to clipboardprint?
SPSite site = new SPSite("http://mosssite/");
SPWeb web=site.OpenWeb();
SPList list = web.GetList("/Information");
foreach (SPField sf in list.Fields)
{
Console.WriteLine(sf.Title);
}
site.dispose();
web.dispose();
SPSite site = new SPSite("http://mosssite/");
SPWeb web=site.OpenWeb();
SPList list = web.GetList("/Information");
foreach (SPField sf in list.Fields)
{
Console.WriteLine(sf.Title);
}
site.dispose();
web.dispose();
2.使用对象模型创建列表，SPListTemplateType.Announcements指定使用通知内容类型作为模板来创建。
注意一定要调用Update()方法。
view plaincopy to clipboardprint?
string listName="TestList";
foreach(SPList currList in web .Lists)
{
if(currList.Title.Equals(listName,StringComparison.InvariantCultureIgnoreCase))
{
list=currList;
break;
}
}
if(list==null)
{
Guid listID=web.Lists.Add(listName,"New nnouncements",SPListTemplateType.Announcements);
list=web.Lists[listID];
list.OnQuickLaunch=true;
list.Update();
}
string listName="TestList";
foreach(SPList currList in web .Lists)
{
if(currList.Title.Equals(listName,StringComparison.InvariantCultureIgnoreCase))
{
list=currList;
break;
}
}
if(list==null)
{
Guid listID=web.Lists.Add(listName,"New nnouncements",SPListTemplateType.Announcements);
list=web.Lists[listID];
list.OnQuickLaunch=true;
list.Update();
}
3.使用对象模型给列表添加item，注意一定要调用Update()方法。
view plaincopy to clipboardprint?
SPListItem newItem = null;
newItem = list.Items.Add();
newItem["Title"] = "AnnouItem1";
newItem["Body"] = "The first AnnouItem1 ";
newItem["Expires"] = DateTime.Now + TimeSpan.FromDays(2);
newItem.Update();
newItem = list.Items.Add();
newItem["Title"] = "AnnouItem2";
newItem["Body"] = "The second AnnouItem2.";
newItem["Expires"] = DateTime.Now + TimeSpan.FromDays(5);
newItem.Update();
SPListItem newItem = null;
newItem = list.Items.Add();
newItem["Title"] = "AnnouItem1";
newItem["Body"] = "The first AnnouItem1 ";
newItem["Expires"] = DateTime.Now + TimeSpan.FromDays(2);
newItem.Update();
newItem = list.Items.Add();
newItem["Title"] = "AnnouItem2";
newItem["Body"] = "The second AnnouItem2.";
newItem["Expires"] = DateTime.Now + TimeSpan.FromDays(5);
newItem.Update();
4.查询item的相关信息
view plaincopy to clipboardprint?
foreach (SPListItem listItem in list.Items)
{
foreach (SPField field in list.Fields)
{
if (!field.Hidden && !field.ReadOnlyField)
Console.WriteLine("{0} = {1}", field.Title, newItem[field.Id]);
}
}
foreach (SPListItem listItem in list.Items)
{
foreach (SPField field in list.Fields)
{
if (!field.Hidden && !field.ReadOnlyField)
Console.WriteLine("{0} = {1}", field.Title, newItem[field.Id]);
}
}
5. 如果你要想得到一个列表的item，你可以通过WebId, ListId, and ID来得到.
view plaincopy to clipboardprint?
SPWeb parentWeb = web.Site.OpenWeb(new Guid(row["WebId"].ToString()));
SPList list = parentWeb.Lists[ new Guid(row["ListId"].ToString()) ];
SPListItem item = list.GetItemById((int.Parse(row["ID"].ToString())));
SPWeb parentWeb = web.Site.OpenWeb(new Guid(row["WebId"].ToString()));
SPList list = parentWeb.Lists[ new Guid(row["ListId"].ToString()) ];
SPListItem item = list.GetItemById((int.Parse(row["ID"].ToString())));
6.使用SPQuery来查询列表中item信息：
view plaincopy to clipboardprint?
SPQuery query = new SPQuery();
query.ViewFields = @"<FieldRef Name='Title'/><FieldRef Name='Created'/>";
query.Query = @"<Where>
<Neq>
<FieldRef Name='Created' />
<Value Type='DateTime'>
<Today /></Value>
</Neq>
</Where>";
SPList list = web.Lists["AnnouList"];
SPListItemCollection items = list.GetItems(query);
foreach (SPListItem expiredItem in items)
{
Console.WriteLine(expiredItem["Title"]);
Console.WriteLine(expiredItem["Created"]);
}
SPQuery query = new SPQuery();
query.ViewFields = @"<FieldRef Name='Title'/><FieldRef Name='Created'/>";
query.Query = @"<Where>
<Neq>
<FieldRef Name='Created' />
<Value Type='DateTime'>
<Today /></Value>
</Neq>
</Where>";
SPList list = web.Lists["AnnouList"];
SPListItemCollection items = list.GetItems(query);
foreach (SPListItem expiredItem in items)
{
Console.WriteLine(expiredItem["Title"]);
Console.WriteLine(expiredItem["Created"]);
}
6.1. ViewFields 表示你查询后要返回的字段
6.2. Query表示查询过滤的表达式，使用CAML语言
7. 使用SPSiteDataQuery来查询列表中item信息
view plaincopy to clipboardprint?
SPSiteDataQuery query = new SPSiteDataQuery();
query.Lists = @"<Lists ServerTemplate='104' />";
query.ViewFields = @"<FieldRef Name='Title'/><FieldRef Name='Created'/>";
query.Webs = "<Webs Scope='SiteCollection' />";
string queryText mailto:=@%22%3CWhere>
<Neq>
<FieldRef Name='Created' />
<Value Type='DateTime'>
<Today /></Value>
</Neq>
</Where>";
query.Query = queryText;
DataTable table = web.GetSiteData(query);
foreach (DataRow row in table.Rows)
{
Console.WriteLine(row["Title"].ToString() + row["Created"].ToString());
}
SPSiteDataQuery query = new SPSiteDataQuery();
query.Lists = @"<Lists ServerTemplate='104' />";
query.ViewFields = @"<FieldRef Name='Title'/><FieldRef Name='Created'/>";
query.Webs = "<Webs Scope='SiteCollection' />";
string queryText mailto:=@%22%3CWhere>
<Neq>
<FieldRef Name='Created' />
<Value Type='DateTime'>
<Today /></Value>
</Neq>
</Where>";
query.Query = queryText;
DataTable table = web.GetSiteData(query);
foreach (DataRow row in table.Rows)
{
Console.WriteLine(row["Title"].ToString() + row["Created"].ToString());
}
7.1. query.Lists = @"<Lists ServerTemplate='104' />";中104代表通知列表类型
7.2 query.Webs = "<Webs Scope='SiteCollection' />";为查询的范围。
7.3. CAML的基本格式是这样的：“<Where><operator><operand /><operand /></operator> </Where>”.
7.4.使用SPQuery返回的是SPListItemCollection，而SPSiteDataQuery可以从不同的列表或是整个网站集查，实际上是返回了一个ADO.NET DataTable对象。
