如何在ASP.NET中创建详细报告

Question

我想在ASP.NET中创建一个包含非常详细数据的报告。此报告应可导出为PDF和Excel。你能告诉我如何做这种报告的提示吗？

我在ReportViewer中链接我的数据集时遇到问题。

使用iTextSharp下载：

NSError *error = NULL;
NSUInteger currentSchemaVersion = [RLMRealm schemaVersionAtPath:[RLMRealm defaultRealmPath] error:&error];
if (currentSchemaVersion == RLMNotVersioned) {
    // new db, skip

} else if (currentSchemaVersion < 26) {
    // kill local db
    [[NSFileManager defaultManager] removeItemAtPath:[RLMRealm defaultRealmPath] error:&error];
    if (error) {
        MRLogError(error);
    }

} else if (error) {
    // for good measure...
    MRLogError(error);
}

// perform realm migration
[RLMRealm setSchemaVersion:26
            forRealmAtPath:[RLMRealm defaultRealmPath]
        withMigrationBlock:^(RLMMigration *migration, NSUInteger oldSchemaVersion) {

        }];

到Excel：

        using iTextSharp.text;
        using iTextSharp.text.html.simpleparser;
        using iTextSharp.text.pdf;
        Response.ContentType = "application/pdf";
        Response.AddHeader("content-disposition", "attachment;filename=this.pdf");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        StringWriter sw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(sw);
        HtmlForm frm = new HtmlForm();
        GridView1.AllowPaging = false;
        GridView1.Parent.Controls.Add(frm);
        frm.Controls.Add(GridView1);
        frm.RenderControl(hw);
        StringReader sr = new StringReader(sw.ToString());
        Document PDFdoc = new Document(PageSize.A4, 10.0F, 10.0F, 10.0F, 0.0F);
        iTextSharp.text.html.simpleparser.HTMLWorker htmlparser =   new iTextSharp.text.html.simpleparser.HTMLWorker(PDFdoc);
        PdfWriter.GetInstance(PDFdoc, Response.OutputStream);
        PDFdoc.Open();
        htmlparser.Parse(sr);
        PDFdoc.Close();
        Response.Write(PDFdoc);
        Response.End();
