Question

我正在尝试将报告查看器添加到我的WPF应用程序中。我已按照This Site上的步骤操作，但现在我收到此错误：

An error occurred during local report processing. The report definition for report 'ConSegReport' has not been specified. Object reference not set to an instance of an object.

这是我的代码：

private void Reportviewer_Load(object sender, EventArgs e)
    {
        if (!_IsReportViewerLoaded)
        {
            Microsoft.Reporting.WinForms.ReportDataSource reportData = new Microsoft.Reporting.WinForms.ReportDataSource();
            Consolidated_DBDataSet conSet = new Consolidated_DBDataSet();
            conSet.BeginInit();

            reportData.Name = "ConSegSet";
            reportData.Value = conSet.Cnsldtd_Performance_tbl;
            this.reportViewer.LocalReport.DataSources.Add(reportData);
            this.reportViewer.LocalReport.ReportEmbeddedResource = "FP Reporting Dashboard.ConSegReport.rdlc";

            conSet.EndInit();

            Consolidated_DBDataSetTableAdapters.Cnsldtd_Performance_tbl_CLONETableAdapter conAD = new Consolidated_DBDataSetTableAdapters.Cnsldtd_Performance_tbl_CLONETableAdapter();
            conAD.ClearBeforeFill = true;
            conAD.Fill(conSet.Cnsldtd_Performance_tbl_CLONE);

            reportViewer.RefreshReport();

            _IsReportViewerLoaded = true;
        }
    }

我还将.rdlc文件设置为＆＃34;复制如果更新＆＃34;输出目录。

我从未尝试过将嵌入式报告引用到上传到SSRS的报告。

这是我的代码，也许会有所帮助：

IReportServerCredentials irsc = new CustomReportCredentials(rc.report_ssrs_username,
    rc.report_ssrs_password, rc.report_ssrs_domain);
ReportViewer1.ServerReport.ReportServerCredentials = irsc;
ReportViewer1.ServerReport.ReportPath = rc.report_ssrs_path;
ReportViewer1.ServerReport.ReportServerUrl = new System.Uri(rc.report_ssrs_url);

SqlConnectionStringBuilder conString = new Database().conBuilder;
List<ReportParameter> parameters = new List<ReportParameter>();
parameters.Add(new ReportParameter("ConString", conString.ConnectionString));
ReportViewer1.ServerReport.SetParameters(parameters);
DataSourceCredentials dsc = new DataSourceCredentials();
dsc.Name = ReportViewer1.ServerReport.GetDataSources()[0].Name;
dsc.UserId = conString.UserID;
dsc.Password = conString.Password;
ReportViewer1.ServerReport.SetDataSourceCredentials(new DataSourceCredentials[] {
    dsc });

ReportViewer1.ShowCredentialPrompts = false;
ReportViewer1.ServerReport.Refresh();

如果您对此处的内容有任何疑问，请与我们联系。我们有一个表定义了所有报告，并查询它以动态呈现reportviewer控件。

作为旁注，我将对RDLC文件使用下划线命名约定。如果代码没有正确计算，那可能会使代码绊倒。另外，尝试引用它将是一个完整的路径来验证这不是一个相对路径问题，如果它试图从调试或发布目录引用该文件。

“ FP Reporting Dashboard.ConSegReport.rdlc”将其更改为“ FP_Reporting_Dashboard.ConSegReport.rdlc”

报告的报告定义＆＃39; [报告名称]＆＃39;尚未指定
