用代码实现task列表里面的Assigned To选择多个人

MSDN帖子记录http://social.msdn.microsoft.com/Forums/zh-CN/sharepointwebpartzhchs/thread/1bef6db4-d95a-4bbb-88e3-ea5e89a0f5e5

Q：

在新建一个task item的Assigned To字段默认只能选择一个人，或者一个组，

但是这里如果我想选择2个人或者2个以上，则不行，需要去Team Site > Tasks > Settings > Edit Column   把 Allow multiple selections 选择Yes

如何用代码实现： Allow multiple selections 选项为 Yes ， 默认为 No

 

A:

using (SPSite site = new SPSite("http://moss:5000"))
         using (SPWeb web = site.RootWeb)
         {
             web.AllowUnsafeUpdates = true;
             SPList list = web.Lists["Tasks"];
             SPFieldLookup userField = list.Fields["Assigned To"] as SPFieldLookup;
             userField.AllowMultipleValues = true;
             userField.Update();
         }
