問題與SharePoint 2010應用程序頁面

我是比較新的SharePoint和正在使用2010年我有應用程序中的頁面我試圖建立與下面的代碼有問題的版本：問題與SharePoint 2010應用程序頁面

using System; 
using Microsoft.SharePoint; 
using Microsoft.SharePoint.WebControls; 
using System.Text; 
using Microsoft.SharePoint.Administration; 
using Microsoft.Office.Server; 
using Microsoft.Office.Server.UserProfiles; 
using Microsoft.SharePoint.Utilities; 

namespace SharePointProject5.Layouts.SharePointProject5 
{ 
    public partial class ApplicationPage1 : LayoutsPageBase 
    { 
     protected void Page_Load(object sender, EventArgs e) 
     { 
      SPContext context = SPContext.Current; 
      StringBuilder output = new StringBuilder();   

      using(SPSite site = context.Site) 
      using (SPWeb web = site.AllWebs["BDC_SQL"]) 
      { 
       UserProfileManager upmanager = new UserProfileManager(ServerContext.GetContext(site)); 
       string ListMgr = ""; 
       string ADMgr = ""; 

       bool allowUpdates = web.AllowUnsafeUpdates; 
       web.AllowUnsafeUpdates = true; 
       web.Update(); 

       SPListCollection listcollection = web.Lists; 
       SPList list = listcollection["BDC_SQL"]; 
       foreach (SPListItem item in list.Items) 
       { 
        output.AppendFormat("<br>From List - Name & manager: {0} , {1}", item["ADName"], item["Manager_ADName"]); 
        UserProfile uProfile = upmanager.GetUserProfile(item["ADName"].ToString()); 
        output.AppendFormat("<br>From Prof - Name & manager: {0} , {1}", uProfile[PropertyConstants.DistinguishedName], uProfile[PropertyConstants.Manager]); 

        ListMgr = item["Manager_ADName"].ToString(); 
        ADMgr = Convert.ToString(uProfile[PropertyConstants.Manager]); 

        if (ListMgr != ADMgr) 
        { 
         output.AppendFormat("<br>This record requires updating from {0} to {1}", uProfile[PropertyConstants.Manager], item["Manager_ADName"]); 
         uProfile[PropertyConstants.Manager].Value = ListMgr; 

         uProfile.Commit(); 

         output.AppendFormat("<br>This record has had its manager updated"); 
        } 
        else 
        { 
         output.AppendFormat("<br>This record does not need to be updated"); 
        } 
       } 

       web.AllowUnsafeUpdates = allowUpdates; 
       web.Update(); 
      } 

      Label1.Text = output.ToString(); 
     } 

    } 
}

一切運行良好直到我加入'uProfile.Commit（）;'線。現在，我收到以下錯誤消息：

我曾嘗試通過在代碼中添加允許不安全的更新，但我仍然得到這個錯誤糾正這一點。

有沒有人對我有任何指導？這將非常感激。

在此先感謝，

馬特。

Best Pattern for AllowUnsafeUpdates

web.AllowUnsafeUpdates = true; 
web.Update(); //remove this line

或檢查您的形式消化

嘗試站點對象上設置allowUnsafeUpdates過，它會看起來像這 -

site.AllowUnsafeUpdates = true; 
UserProfileManager upmanager = new UserProfileManager(ServerContext.GetContext(site));

我的猜測是UserPro fileManager在站點之外創建一個Web對象，並在它使用的Web上繼承該設置。
我希望你已經想通了這一點...

嘗試消化驗證頁面反對的SharePoint，而不是打開不安全的更新（不是一個好的做法）

protected override void OnInit(EventArgs e) 
    { 
     SPUtility.ValidateFormDigest(); 
     base.OnInit(e); 
    }

也儘量做發佈更新請求，更新GET請求也不是一個好的做法和安全風險
