SharePoint CSOM 处理人员和组字段

　　前言

　　最近，在做SharePoint Online 数据迁移的工作，于是乎，就有了处理人员和组字段的需求。

　　正文

　　首先，需要获取字段的值未FieldUserValue[]类型，然后，每个用户都需要在新站点EnsuerUser一下，确保在新站点上已经存在。

if (sourceItem.FieldValues["Users"] != null)
{
FieldUserValue[] fUsers1 = sourceItem.FieldValues["Users"] as FieldUserValue[];
FieldUserValue[] users1 = new FieldUserValue[fUsers1.Length];
for (int m = 0; m < fUsers1.Length; m++)
{
    try
    {
        User TempUser = targetWeb.EnsureUser(fUsers1[m].Email);
        targetContext.Load(TempUser);
        targetContext.ExecuteQuery();
        FieldUserValue fieldUserVal = new FieldUserValue();
        fieldUserVal.LookupId = TempUser.Id;
        users1.SetValue(fieldUserVal, m);
    }
    catch{}
}

newItem["Users"] = users1;
newItem.Update();
targetContext.ExecuteQuery();
}

　　结束语

　　其实，在处理的过程中，还需要判断其中是否有User已经不在Talent里了的情况，防止程序报错。
