以下代码在调试时引发异常-

 class Program
    {
        static void Main(string[] args)
        {
            //Customise parameters for render method
            Warning[] warnings;
            string[] streamIds;
            string mimeType = "application/pdf";
            string encoding = String.Empty;
            string filenameExtension = String.Empty;
            string deviceInfo = "<DeviceInfo>" + "<OutputFormat>PDF</OutputFormat>" + "<PageWidth>8.5in</PageWidth>" + "<PageHeight>11in</PageHeight>" + "<MarginTop>0.5in</MarginTop>" + "<MarginLeft>1in</MarginLeft>" + "<MarginRight>1in</MarginRight>" + "<MarginBottom>0.5in</MarginBottom>" + "</DeviceInfo>";
            //Create a SqlConnection to the AdventureWorks2008R2 database. 
            SqlConnection connection = new SqlConnection("data source=localhost;initial catalog=AdventureWorks2008R2;integrated security=True");
            //Create a SqlDataAdapter for the Sales.Customer table.
            SqlDataAdapter adapter = new SqlDataAdapter();
            // A table mapping names the DataTable.
            adapter.TableMappings.Add("Table", "Sales.Customer");
            // Open the connection.
            connection.Open();
            Console.WriteLine("'nThe SqlConnection is open.");
            // Create a SqlCommand to retrieve Suppliers data.
            SqlCommand command = new SqlCommand("SELECT Sales.Customer.CustomerID,Sales.Customer.PersonID,Sales.Customer.StoreID,Sales.Customer.TerritoryID,Sales.Customer.AccountNumber,Sales.Customer.rowguid,Sales.Customer.ModifiedDate FROM Sales.Customer", connection);
            command.CommandType = CommandType.Text;
            // Set the SqlDataAdapter's SelectCommand.
            adapter.SelectCommand = command;
            command.ExecuteNonQuery();
            // Fill the DataSet.
            DataSet dataset = new DataSet("Sales.Customer");
            adapter.Fill(dataset);
            //set up Reportviewver
            Microsoft.Reporting.WinForms.LocalReport viewer = new Microsoft.Reporting.WinForms.LocalReport();
            viewer.ReportPath = @"C:'Documents and Settings'murali.madhava'My Documents'Visual Studio 2008'Projects'PdfReportGeneration'PdfReportGeneration'Report.rdlc";

           //add data source.
           viewer.DataSources.Clear();
           viewer.DataSources.Add(new ReportDataSource("dataset", dataset.Tables[0]));

           //Now render it to pdf
           try
           {
            byte[] bytes = viewer.Render("PDF", deviceInfo, out mimeType, out encoding, out filenameExtension, out streamIds, out warnings);
            using (System.IO.FileStream fs = new System.IO.FileStream("output.pdf", System.IO.FileMode.Create))
            {
                //file saved to bin directory
                    fs.Write(bytes, 0, bytes.Length);
                }
                //Save report to D:'
                // FileStream fsi = new FileStream(@"D:'output.pdf", FileMode.Create);
            }
            catch (Exception e)
            {
                Console.WriteLine("'nCHEY!!!this Exception encountered:", e);
            }

                        // Close the connection.
                        connection.Close();
                        Console.WriteLine("'nThe SqlConnection is closed.");
                        Console.ReadLine();
        }
    }

使用的Winform版本是9.0.0.0,我使用了Adventureworks2008R2.Exception说:"本地报告处理过程中发生错误"。如何遇到这种情况?

渲染 rdlc 文件时引发异常

这里的问题出在语句上

viewer.DataSources.Add(new ReportDataSource("dataset", dataset.Tables[0]));

此处提到的"数据集"名称应与 .rdlc 报表中使用的数据集名称相同。单击报表元素属性以查看它使用的数据集。并提供来自查询数据集的完全相同的数据'数据集。表[0]'。它有效。
