Question

尝试以编程方式添加sharepoint 2010 Web应用程序中的用户策略时出现此错误：

Operation is not valid due to the current state of the object.

这是一个代码示例：

public Boolean AddUser(SoftwareUser user)
    {
        SPSecurity.RunWithElevatedPrivileges(delegate()
        {
            using (site = new SPSite(siteUrl))
            {
                using (web = site.RootWeb)
                {
                    web.AllowUnsafeUpdates = true;
                    SPUser spUser = web.EnsureUser(user.UserShortname);
                    web.Groups["MySolution Members"].AddUser(spUser);
                    if (spUser != null)
                    {
                        if (user.Email != null)
                        {
                            spUser.Email = user.Email;
                        }
                        spUser.Update();
                        SPWebApplication webApp = site.WebApplication;
                        SPPolicy policy = webApp.Policies.Add(spUser.Name, "deny");
                        policy.PolicyRoleBindings.Add(webApp.PolicyRoles["deny"]);
                        webApp.Update();
                    }
                    web.AllowUnsafeUpdates = false;
                }
            }
        });
        return true;
    }

提前谢谢。

在下面找到stacktrace：

请勿在Elevated Permissions委托中调用.Update() 只需在SPSecurity.RunWithElevatedPrivileges

下面进行操作即可

由于对象的当前状态，操作无效。（SPWebApplication.Update）
