以编程方式设计动态RDLC

using System;
using System.Data;
using Microsoft.Reporting.WinForms;

public class DynamicRDLCExample
{
    public void CreateDynamicReport()
    {
        // 创建一个数据集
        DataSet dataSet = new DataSet();
        DataTable dataTable = new DataTable("SampleData");
        dataTable.Columns.Add("Name", typeof(string));
        dataTable.Columns.Add("Age", typeof(int));

        // 添加一些示例数据
        dataTable.Rows.Add("Alice", 30);
        dataTable.Rows.Add("Bob", 25);

        dataSet.Tables.Add(dataTable);

        // 创建报表视图
        ReportViewer reportViewer = new ReportViewer();
        reportViewer.ProcessingMode = ProcessingMode.Local;

        // 动态创建RDLC报表
        LocalReport localReport = reportViewer.LocalReport;
        localReport.ReportPath = "DynamicReport.rdlc"; // 报表文件路径

        // 添加数据源
        localReport.DataSources.Add(new ReportDataSource("SampleData", dataSet.Tables["SampleData"]));

        // 渲染报表
        string mimeType;
        string encoding;
        string fileNameExtension;
        string[] streams;
        Warning[] warnings;

        byte[] renderedBytes = localReport.Render(
            "PDF", null, out mimeType, out encoding, out fileNameExtension,
            out streams, out warnings);

        // 将报表保存为PDF文件
        System.IO.File.WriteAllBytes("DynamicReport.pdf", renderedBytes);
    }
}

localReport.DataSources.Add(new ReportDataSource("SampleData", dataSet.Tables["SampleData"]));

localReport.ReportPath = "DynamicReport.rdlc"; // 确保路径正确
