在SharePoint 2010中通过客户端对象模型获取多选列中的值

一小段代码，用于解释如何用客户端对象模型同多选列中添加并获取值。

ListItemCollection listItems = list.GetItems(camlQuery);

//Add values -

listItems[0]["MultiChoiceField"] = newstring[] {“Choice 1″,”Choice 4″ };

//Retrieve -

if (listItems[0]["testmultichoice"] != null)
{
string[] values = listItems[0]["testmultichoice"] as string[];

if (values != null)
{
var result = from c in values where c.Contains(searchChoice) select c;
if (result != null)
choices = result.ToList();
}

}
return choices;
