最基础的PUSH方法的水晶报表

   
protected void Page_Load(object sender, EventArgs e)
    {
        ReportDocument oRpt = new ReportDocument();
        string RptDir = "E:\\My Document\\Demo8\\CrystalReport.rpt";
        oRpt.Load(RptDir);
  
        DataSet myset = new DataSet1();
        String cnnstr = "server=localhost;uid=sa;pwd=;database=YJSBDB";
        String sqlstr = "Select * from BuMXXB";
        SqlConnection sqlcnn = new SqlConnection(cnnstr);
        SqlDataAdapter myadapter = new SqlDataAdapter(sqlstr, sqlcnn);
        myadapter.Fill(myset, "BuMXXB");
       
        oRpt.SetDataSource(myset);  
        CrystalReportViewer1.ReportSource=oRpt;
    }

大概思路：创建报表-〉加载报表-〉将数据集放入DataSet -〉报表从数据集中回去数据
