如何在Crystal Reports中使用带参数的存储过程？我在VS 2013，asp.net，MVC和razor中使用以下代码。

 public ActionResult AllCustomerReports()
 {
     ReportDocument rd = new ReportDocument();
     rd.Load(Server.MapPath("\\Reports\\rpt_AllCustomers.rpt"));
     rd.SetDataSource(db.CUSTOMERs.Select(p => new
     {
         Id = p.Id,
         CUSTOMER_CODE = p.CUSTOMER_CODE,
         CUSTOMER_NAME = p.CUSTOMER_NAME,
         CUSTOMER_EMAIL_ADDRESS = p.CUSTOMER_EMAIL_ADDRESS,
         CUSTOMER_LANDLINE = p.CUSTOMER_LANDLINE,
         CUSTOMER_TYPE_ID = p.CUSTOMER_TYPE.Id,
         CUSTOMER_TYPE_NAME = p.CUSTOMER_TYPE.CUSTOMER_TYPE_NAME,
         LOCATION_TYPE_ID = p.LOCATION_TYPE.Id,
         LOCATION_TYPE_NAME = p.LOCATION_TYPE.LOCATION_TYPE_NAME,
         INDUSTRY_TYPE_ID = p.INDUSTRY_TYPE.Id,
         INDUSTRY_TYPE_NAME = p.INDUSTRY_TYPE.INDUSTRY_TYPE_NAME
     }).ToList());

     Response.Buffer = false;
     Response.ClearContent();
     Response.ClearHeaders();
     Stream stream = rd.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
     stream.Seek(0, SeekOrigin.Begin);
     return File(stream, "application/pdf", "ListofAllCustomers.pdf");
}

您必须先在数据集或数据表中获取数据库记录，然后将该数据分配给报告，如下所示。 无需在报告中传递参数即可获取数据。您可以在sp direct 中传递这些参数。

DataSet ds = get data from database which call sp with parameter;                

string reportPath = Server.MapPath("~/Reports/XXXXX.rpt");
reportDocument.Load(reportPath);

DataTable dt = ds.Tables[0].Copy();

reportDocument.SetDataSource(dt);

CrystalReportViewer.ReportSource = reportDocument;
CrystalReportViewer.DataBind();

在报告中使用包含参数的存储过程
