从Reportviewer以黑白PDF渲染LocalReport

Question

这是我从ReportViewer以PDF格式导出报告的方式：

Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
byte[] myBytes;
string reportName = hfReportName.Value;

myBytes = rvReport.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);

Response.Buffer = true;
Response.Clear();  
Response.ContentType = mimeType;
Response.AddHeader("content-disposition", "attachment; filename=" + reportName + "_" + ddlPracGroup.SelectedItem + "." + extension);
Response.BinaryWrite(myBytes);
Response.Flush();

是否可以在Black and White仅导出此报告？

Answer 1

如果有人提出这个问题，我会发布我的解决方案。

我在rdlc报告IsPrintType中再添加一个参数。这是布尔参数。在SSRS中，您可以将报告设置为仅黑白。单击打印按钮reload report with this parameter > print report using code above > reload report back with color
