我正在使用Umbraco 7.5.7作为我的应用程序当我点击CMS中的内容项时它会向我显示此错误，我已经提供了下面的代码，可以帮助我解决这个问题。 在访问内容和投掷时，Umbraco CMS中的HttpContext.Current.Session和UmbracoContext.Current.HttpContext.Session始终为null 从服务器收到错误 - ＆＃34;值不能为空。参数名称：httpSessionState＆＃34; cms UI上的错误

IManageState.cs 

public interface IManageState
{
void SetValue(string key, object data);
bool HasKey(string key);
T GetValue<T>(string key);
bool SessionIdExists();
}

SessionContext.cs 

protected readonly IManageState SessionManager;
public SessionContext()
{
     SessionManager = new HttpSessionManager();
}

HttpSessionManager.cs 

public class HttpSessionManager : IManageState
{

private readonly HttpSessionStateBase _session;
public HttpSessionManager()
{
}
public HttpSessionManager(HttpSessionStateBase session)
{
    _session = session;
}
public HttpSessionStateBase Session
{
    get { return _session ?? new HttpSessionStateWrapper(HttpContext.Current.Session); }//getting null here for HttpContext.Current.Session
}
public void SetValue(string key, object data)
{
    Session[key] = data;
}
public bool HasKey(string key)
{
    return Session[key] != null;
}
public T GetValue<T>(string key)
{
    return HasKey(key) ? (T)Session[key] : default(T);
}
public bool SessionIdExists()
{
    if (HttpContext.Current.Session == null)
    {
        return false;
    }
    string cookieHeader = HttpContext.Current.Request.Headers[GenericConstants.Cookie];
    return !string.IsNullOrEmpty(cookieHeader)
           && cookieHeader.IndexOf(GenericConstants.AuthorizationCode, StringComparison.OrdinalIgnoreCase) >= 0
           && HttpContext.Current.Request.Cookies[GenericConstants.DOTNETSESSIONID] != null
           && Session[GenericConstants.AuthorizationCode] != null
           && HttpContext.Current.Request.Cookies[GenericConstants.AuthorizationCode] == Session[GenericConstants.AuthorizationCode];
}
}

我也试过下面的代码，我换了这行

get { return _session ?? new HttpSessionStateWrapper(HttpContext.Current.Session); }

带

get { return _session != null ? _session : HttpContext.Current.Session != null ? new HttpSessionStateWrapper(HttpContext.Current.Session):  UmbracoContext.Current.HttpContext.Session ; }
