SharePoint【学习笔记】-- SharePoint 权限提升和杜绝当前上下文环境影响

权限提升的方式：

SPSecurity.RunWithElevatedPrivileges(delegate() 
{ 
    ListItem.Web.AllowUnsafeUpdates = true; 
    ListItem["ZhDocID"] = DocID; 
    ListItem["ZhDocDescription"] = DocDescription; 
    ListItem["ZhIsControlled"] = DocIsControlled; 
    ListItem["ZhDocStatus"] = DocStatus; 
    ListItem["ZhDocIssuedStatus"] = DocIssuedStatus; 
    ListItem["ZhDocIssuedTime"] = DocIssuedTime; 
    ListItem["ZhDocSignInTime"] = DocSignInTime; 
    ListItem["ZhDocSURL"] = DocSURL; 
    string strZhDocIssuedDetails = ""; 
    if (DocStateInBMList != null && DocStateInBMList.Count > 0) 
    { 
        strZhDocIssuedDetails = string.Join(";", DocStateInBMList.ToArray()); 
    } 
    ListItem["ZhDocIssuedDetails"] = strZhDocIssuedDetails; 
    ListItem.SystemUpdate(); 
});
