的代碼塊在我的網頁加載只是爲了測試目的所以可以得到一個直接結果....但它從來沒有到頁面的加載在生產，但能正常工作本地計算機上的VS調試時...

IIdentity id = WindowsIdentity.GetCurrent(); 
     WindowsIdentity winId = id as WindowsIdentity; 

     if (id == null) 
     { 
      txtDetailedProblem.Text = "Identity is not a windows identity"; 
      return; 
     } 

     string userInQuestion = winId.Name.Split('\\')[1]; 
     string myDomain = winId.Name.Split('\\')[0]; // this is the domain that the user is in 
     // the account that this program runs in should be authenticated in there      
     DirectoryEntry entry = new DirectoryEntry("LDAP://" + myDomain); 
     DirectorySearcher adSearcher = new DirectorySearcher(entry); 

     adSearcher.SearchScope = SearchScope.Subtree; 
     adSearcher.Filter = "(&(objectClass=user)(samaccountname=" + userInQuestion + "))"; 
     SearchResult userObject = adSearcher.FindOne(); 
     if (userObject != null) 
     { 
      string[] props = new string[] {"mail"}; 
      foreach (string prop in props) 
      { 
       txtTEST.Text = prop.ToString() + " " + userObject.Properties[prop][0].ToString(); 
      } 
     }

IIdentity id = WindowsIdentity.GetCurrent(); 
      WindowsIdentity winId = id as WindowsIdentity; 

      if (id == null) 
      { 
       CurrentUserEmail = "identity is not a windows identity"; 
       return; 
      } 

      var name = winId.Name; 

      string userInQuestion = name.Split('\\')[1]; 
      string myDomain = name.Split('\\')[0]; // this is the domain that the user is in 
      // the account that this program runs in should be authenticated in there      

      using (HostingEnvironment.Impersonate()) 
      { 
       DirectoryEntry entry = new DirectoryEntry("LDAP://" + myDomain); 
       DirectorySearcher adSearcher = new DirectorySearcher(entry); 

       adSearcher.SearchScope = SearchScope.Subtree; 
       adSearcher.Filter = "(&(objectClass=user)(samaccountname=" + userInQuestion + "))"; 
       SearchResult userObject = adSearcher.FindOne(); 
       if (userObject != null) 
       { 
        string[] props = new string[] {"mail"}; 
        foreach (string prop in props) 
        { //when it works set variable to CurrentUserEmail instead of txtDetailPrblem textbox 
         CurrentUserEmail = userObject.Properties[prop][0].ToString(); 
        } 
       } 

      }
