后台

rep1 = windowsFormsHost1.Child as ReportViewer;
                    rep1.ProcessingMode = ProcessingMode.Remote;
                    serverReport = rep1.ServerReport;

 // 获得服务器证书
                    ReportServerCredentials rsCredentials =
                        serverReport.ReportServerCredentials;

//用户账户密码

                    if (string.IsNullOrEmpty(reportInfo.ReportServerBrowserName) || string.IsNullOrEmpty(reportInfo.ReportServerBrowserPassword))
                    {
                        rsCredentials.NetworkCredentials = System.Net.CredentialCache.DefaultCredentials;
                    }
                    else
                    {
                        rsCredentials.NetworkCredentials = new NetworkCredential(reportInfo.ReportServerBrowserName, reportInfo.ReportServerBrowserPassword);
                    }

// 设置报表服务地址和路径
                    serverReport.ReportServerUrl = new Uri(reportInfo.ReportServerIpAddress);
                    serverReport.ReportPath = reportInfo.ReportPath;

// 设置报表的参数 ：用户ID

                    if (serverReport.GetParameters().FirstOrDefault(p => p.Name == "UserID") != null)
                    {
                        serverReport.SetParameters(new ReportParameter("UserID", Authentication.UserID.ToString()));
                    }

//刷新报表

rep1.RefreshReport();

顺便说一下，据说之前是可以用的，浏览器访问发布的报表也是可以浏览报表数据，就是再wpf运行的时候不报异常也显示不出来报表内容，甚至鼠标放在页面是有上下页提示的，下图

另外 之前好像是vs的旧版本 win7的系统  我现在本地是win10和vs2015,不知道是不是这些差异导致的，实在找不到原因了，跪求解决
