推荐答案

您正在使用变量CrystalReportViewer1(类型为 ReportDocument [ 如何在项目中使用Crystal Report? [使用带有数据集的C#创建Crystal报表 [

You are using the variable CrystalReportViewer1 (of type CrystalReportViewer[^]) as a type. So your code really makes no sense.
I suspect you wanted to create a new ReportDocument[^] to attach to the CrystalReportViewer1.

Have a look at the below CP articles on how to use CrystalReportViewer. They are ''old'' but should still be useful.

I hope this helps.

CrystalReportViewer report = new CrystalReportViewer();

CrystalReportViewer report = new CrystalReportViewer();

您需要先创建 .rpt 然后将其加载到 ReportDocument

试试这个:

you need to create the .rpt first and then load it to ReportDocument

Try this :

protected void Page_Load(object sender, EventArgs e)
    {
 
        ReportDocument crypt = new ReportDocument();
        CrystalReportViewer1.Visible = true;
        DataSet ds = new DataSet("DataSet1");
        DataTable table = new DataTable("DataSet1");
 
        table.Columns.Add("username", typeof(System.String));
        table.Columns.Add("bookno", typeof(System.String));
 
        DataRow row = table.NewRow();
        row["username"] = "Farooq";
        row["bookno"] = "hyden";
        ReportDocument crypt = new ReportDocument();
            string path="D:\\Projects\\CrystalDemo\\CrystalDemo\\CrystalReport1.rpt";
            crypt.Load(path);
            crypt.SetDataSource(ds);
            crystalReportViewer1.ReportSource = crypt;
            crystalReportViewer1.Refresh();
        
 
    }
