如何获得正确的SPFieldUservalue以使用SpsitedataQuery为某些用户汇总任务？

Question

我正在尝试为某个用户收集某个内容类型的所有任务。要完成此目的，我正在使用spsitedataquery，它看起来像这样：

string where = String.Format(@"<Where>
                                        <And>
                                            <BeginsWith>
                                                <FieldRef Name='ContentTypeId'/>
                                                <Value Type='Text'>0x0108010031C20CDC28544f93B27958D36ACBE2F5</Value>
                                            </BeginsWith>
                                            <Eq>
                                                <FieldRef Name='AssignedTo'/>
                                                <Value Type='Text'>{0}</Value>
                                            </Eq>
                                        </And>
                                     </Where>", userValue.ToString());
query.Query = where;
DataTable results = web.GetSiteData(query);

.

如果我只想过滤内容类型但是过滤用户失败的情况下，它会正常工作。

这里是我认为问题是..分配的字段包含视图的值

17;#TestUser01

.

但我的常规loginname包含索赔字符串和域，看起来像这样

i:0#.w|test\TestUser01

.

我试图创建spfielduservalue以获取位于AssendedTo-Field中找到的相同的用户字符串..如此：

SPFieldUserValue userValue = new SPFieldUserValue(web, SPContext.Current.Web.CurrentUser.ID, SPContext.Current.Web.CurrentUser.LoginName);

.

..但是我只是获得一个如下所示值：

17;#i:0#.w|test\TestUser01

.

..而且我仍然没有来自我的查询的结果..

如何获得正确的字符串来执行我的查询？

By changing the CAML like this:

string where = @"<Where>
                                        <And>
                                            <BeginsWith>
                                                <FieldRef Name='ContentTypeId'/>
                                                <Value Type='Text'>0x0108010031C20CDC28544f93B27958D36ACBE2F5</Value>
                                            </BeginsWith>
                                            <Eq>
                                                <FieldRef Name='AssignedTo' LookupId='TRUE' />
        <Value Type='Integer'><UserID /></Value>
                                            </Eq>
                                        </And>
                                     </Where>";
query.Query = where;
DataTable results = web.GetSiteData(query);

it will fetch for current user :)

If you need to specify another user you can use:

string where = String.Format(@"<Where>
                                        <And>
                                            <BeginsWith>
                                                <FieldRef Name='ContentTypeId'/>
                                                <Value Type='Text'>0x0108010031C20CDC28544f93B27958D36ACBE2F5</Value>
                                            </BeginsWith>
                                            <Eq>
                                                <FieldRef Name='AssignedTo' LookupId='TRUE' />
                                                <Value Type='Integer'>{0}</Value>
                                            </Eq>
                                        </And>
                                     </Where>", userValue.ToString());
query.Query = where;
DataTable results = web.GetSiteData(query);

and just make sue you have the ID of the user in userValue

Answer 2

The CAML Query for fetching the values for current user is:

"<Where><Eq><FieldRef Name='AssignedTo' /><Value Type='Integer'><UserID Type='Integer' /></Value></Eq></Where>";

And for another user it should be as mentioned by @Robert.
