小编Jar*_*yer的帖子

我有一个保存在SQL2005报告服务器上的报告,我想返回此报告的呈现PDF.我在使用本地*.rdlc文件时已经想到了这一点(我已经在博客上发表过这篇文章),但是当*.rdl驻留在报表服务器上时却没有.我在线上收到401 Not Notized错误...

reportViewer.ServerReport.SetParameters(reportDefinition.ReportParameters);

这是用于呈现报告的方法.

public byte[] Render(IReportDefinition reportDefinition)
{
    var reportViewer = new ReportViewer();
    byte[] renderedReport;
    try
    {
        var credentials = new WindowsImpersonationCredentials();
        reportViewer.ServerReport.ReportServerUrl = new Uri("http://myssrsbox", UrlKind.Absolute);
        reportViewer.ServerReport.ReportServerCredentials = credentials;
        reportViewer.ServerReport.ReportPath = reportDefinition.Path;
        // Exception is thrown on the following line...
        reportViewer.ServerReport.SetParameters(reportDefinition.ReportParameters);

        string mimeType;
        string encoding;
        string filenameExtension;
        string[] streams;
        Warning[] warnings;

        renderedReport = reportViewer.ServerReport.Render(reportDefinition.OutputType, reportDefinition.DeviceInfo, out mimeType, out encoding, out filenameExtension, out streams, out warnings);
    }
    catch (Exception ex)
    {
        // …

我正在构建一个类来在会话中存储用户ID和用户角色.我不确定当多个用户同时在网站上时这个类会如何表现.有没有人看到这个问题？

public static class SessionHandler
    {   
        //*** Session String Values ***********************

        private static string _userID = "UserID";
        private static string _userRole = "UserRole";

        //*** Sets and Gets **********************************************************

        public static string UserID
        {
            get
            {
                if (HttpContext.Current.Session[SessionHandler._userID] == null)
                { return string.Empty; }
                else
                { return HttpContext.Current.Session[SessionHandler._userID].ToString(); }
            }
            set
            { HttpContext.Current.Session[SessionHandler._userID] = value; }

        }
        public static string UserRole
        {
            get
            {
                if (HttpContext.Current.Session[SessionHandler._userRole] == null)
                { return string.Empty; }
                else
                { return HttpContext.Current.Session[SessionHandler._userRole].ToString(); }
            }
            set
            { HttpContext.Current.Session[SessionHandler._userRole] …
