Question

我有一个在IIS 7服务器上运行的应用程序，在这个程序中我需要找到当前用户所属的所有组。当我使用服务器上的浏览器访问网站时，它运行正常，但是当我尝试从我的机器访问它时，它会不断抛出COM异常，这是我用来获取用户组的代码。

private List<string> GetUserGroups(string userName)
{
    //The list of strings for output.
    List<string> output= new List<string>();
    try
    {
        //creating a PrincipalContext object in a using block for easy disposal
        using(PrincipalContext domain = new PrincipalContext(ContextType.Domain,"domain"))
        //using(WindowsIdentity user = WindowsIdentity.GetCurrent())
        {

            //Creating a UserPrincipal from the PrincipalContext by finding the user that 
            //was passed to the function

            //This is the line that keeps throwing the exception.
            using (UserPrincipal user = UserPrincipal.FindByIdentity(domain,IdentityType.SamAccountName,userName))
            {
                //Checking to make sure the user was found.
                if (user != null)
                {
                    //Getting the users groups in a collection variable called groups
                    PrincipalSearchResult<Principal> groups = UserPrincipal.Current.GetAuthorizationGroups();
                    //IdentityReferenceCollection groups = user.Groups;
                    //This foreach loop goes through each result in the groups collection
                    foreach (Principal p in groups)
                    {
                        //check the result is a GroupPrincipal object and is not null
                        if (p is GroupPrincipal && p.ToString() != null)
                        {
                            output.Add(p.ToString());//Add the string value to the output list.
                            debugString += "<br/>"+p.ToString();
                        }
                    }
                }
            }
        }
    }
    catch (Exception ex)
    {
        processLog.Text += ex.ToString()+ ex.GetType();
    }
    //return the list of groups the user is a member of.
    return output;
}

当我从服务器以外的位置访问异常时，为什么会抛出异常？我该如何解决？

更新：这是stacktrace异常和所有

System.Runtime.InteropServices.COMException（0x80072020）：An 发生操作错误。在 System.DirectoryServices.DirectoryEntry.Bind（Boolean throwIfFail）at System.DirectoryServices.DirectoryEntry.Bind（）at System.DirectoryServices.DirectoryEntry.get_AdsObject（）at System.DirectoryServices.PropertyValueCollection.PopulateList（）at System.DirectoryServices.PropertyValueCollection..ctor（的DirectoryEntry entry，String propertyName）at System.DirectoryServices.PropertyCollection.get_Item（字符串 propertyName）at System.DirectoryServices.AccountManagement.PrincipalContext.DoLDAPDirectoryInitNoContainer（）在 System.DirectoryServices.AccountManagement.PrincipalContext.DoDomainInit（）在 System.DirectoryServices.AccountManagement.PrincipalContext.Initialize（）在 System.DirectoryServices.AccountManagement.PrincipalContext.get_QueryCtx（）在 System.DirectoryServices.AccountManagement.Principal.FindByIdentityWithTypeHelper（PrincipalContext context，Type principalType，Nullable`1 identityType，String identityValue，DateTime refDate）at System.DirectoryServices.AccountManagement.Principal.FindByIdentityWithType（PrincipalContext context，Type principalType，IdentityType identityType，String identityValue）at System.DirectoryServices.AccountManagement.UserPrincipal.FindByIdentity（PrincipalContext context，IdentityType identityType，String identityValue）at ResetUnlockAccount.ResetUnlockAccount.GetUserGroups（String userName）在 C：\ ResetUnlockAccount \ ResetUnlockAccount \ ResetUnlockAccount.aspx.cs：行 894

Answer 1

根据OP的评论，

答案在这里找到：GroupPrincipal method FindByIdentity throw strange exception

只需添加using System.Web.Hosting;和   using(HostingEnvironment.Impersonate())超过第一次使用   原始代码。

asp.net应用程序userprincipal.findbyidentity与服务器上的浏览器一起使用，从我的机器抛出异常
