• VS2010 水晶报表的使用


    在VS2010中新建一个“Windows 窗体应用程序”项目,在该项目中添加一个水晶报表“CrystalReport1.rpt”,然后在项目上点击鼠标右键属性,将“目标框架”改为“.Net Framework 4”

    打开app.config文件,在“startup”节点一个“useLegacyV2RuntimeActivationPolicy="true"”属性

    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
    </startup>

    在Form1窗体中,从工具箱拖出一个Crystal Report Viewer控件,双击Form窗体,是双击Form窗体,不是Crystal Report Viewer,在后台的Form_Load事件中写入如下代码:

    private void Form1_Load(object sender, EventArgs e)
            {
                string connStr = "Data Source=.\SqlExpress;Initial Catalog=dbTest;User ID=sa;Password=test";
                SqlConnection conn = new SqlConnection(connStr);
                conn.Open();
                try
                {
                    string sql = "SELECT * FROM Customer where email!='test@gmail.com'";
                    SqlDataAdapter sda = new SqlDataAdapter(sql, conn);
                    DataSet ds = new DataSet();
                    sda.Fill(ds, "tmpTable");
    
                    string reportPath = System.Windows.Forms.Application.StartupPath + @"CrystalReport1.rpt";
                    ReportDocument rd = new ReportDocument();
                    rd.Load(reportPath);
                    rd.SetDataSource(ds.Tables[0].DefaultView);
                    this.crystalReportViewer1.ReportSource = rd;
                }
                catch (Exception ex)
                {
                    throw new Exception(ex.Message.ToString());
                }
                finally
                {
                    conn.Close();
                }
            }

    这样就OK了
