SSRS 2016：将报表加载到服务器时出现 NullReferenceException 和 ReportServerException

Question

我在远程模式下使用 Microsoft ReportViewer 查看存储在本地的报告。该代码似乎无法 将报告 上传到 SQL 2016（虽然与 SQL 2014 一起工作良好）命令 NullReferenceException ServerReport.LoadReportDefinition(...).

我的代码有错误还是 ReportViewer 错误？是不是省略了什么设置？

我知道 What is a NullReferenceException, and how do I fix it?，但我从 Microsoft 代码的深度得到了异常，我可以访问的对象中有 none 是 null。

重现步骤

创建一个新的 winforms 项目
向 Form1 添加工具箱中的 Reporting/ReportViever (reportViewer1)
Install-Package Microsoft.ReportingServices.ReportViewerControl.Winforms（安装版本140.1000.523 october 2017）
将以下代码粘贴（修改报表路径和服务器名称）到 Form1：

    private void Form1_Load(object sender, EventArgs e)
        {
            reportViewer1.ProcessingMode = ProcessingMode.Remote;
            reportViewer1.ShowCredentialPrompts = true;
            reportViewer1.ServerReport.ReportServerUrl =new Uri("http://MyServer/ReportServer");
            using (var tr = System.IO.File.OpenText(@"c:\ ... \MyReport.rdl"))
            {
                reportViewer1.ServerReport.LoadReportDefinition(tr);
            }
            this.reportViewer1.RefreshReport();
        }

当 MyServer 为 SQL Server 2014 时，报告会按预期在查看器中呈现。当服务器是 SQL Server 2016（甚至 2017）时，我在第 reportViewer1.ServerReport.LoadReportDefinition 行。我相信第二个例外是第一个例外的结果。

完全异常：

第一个：

报表在 Report Builder 2014 中打开时，可以毫无问题地在两台服务器上呈现。当报表已上传到服务器时（.ReportPath = 替换 .LoadReportDefinition(），Report Viewer 控件可以呈现它。
编辑

问题已报告给Microsoft SSRS report viewer crashes when uploading a report to Report Sever 2016

Answer 1

我不熟悉 LoadReportDefintion API，但是从调用堆栈来看，LoadReportDefinition API 调用没有通过 Publish RDL 路径中的 upgrade\downgrade 代码路径.

请将您的报告升级到 2016 架构、最新的 Report Builder 或 SSDT，然后重试。

Answer 2

问题现已在 Microsoft.ReportingServices.ReportViewerControl.Winforms 150.900.148 中得到纠正。

在向开发团队报告问题后，我被要求提供更详细的信息，问题得到确认和更正。（感谢 Brad Syputa - Microsoft）。
