RDLC报告索引超出了数组asp net核的范围。
在asp net核心mvc中使用调试模式时，索引超出了数组错误的范围，但在非调试模式(Shift+F5)中运行时，索引是可以的。
在这里，错误描述的细节：
处理请求时发生了未处理的异常。IndexOutOfRangeException:索引超出了数组的界限。AspNetCore.ReportingServices.RdlExpressions.ExpressionHostObjectModel.RemoteArrayWrapper.get_Item(int指数
ReportProcessingException:报表处理中发生意外错误。索引超出了数组的界限。AspNetCore.ReportingServices.ReportProcessing.Execution.RenderReport.Execute(IRenderingExtension newRenderer)
LocalProcessingException:在本地报表处理期间发生错误。在报表处理中发生意外错误。索引超出了数组的界限。AspNetCore.Reporting.InternalLocalReport.InternalRender(string格式，bool allowInternalRenderers，string deviceInfo，PageCountMode pageCountMode，CreateAndRegisterStream createStreamCallback，out Warning[]警告)
在这里，我导出到pdf代码：
int extension = 1;
var path = $"{this._webHostEnvironment.WebRootPath}\\Report\\RptDO2.rdlc";
Dictionary<string, string> parameters = new Dictionary<string, string>();
Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
Encoding.GetEncoding("windows-1252");
parameters.Add("txtto", inv.Quotation.CustomerContact.Customer.CompanyName);
parameters.Add("txtaddress_detail", inv.Quotation.CustomerContact.Customer.Address1 + "\r\n"
+ inv.Quotation.CustomerContact.Customer.Address2 + "- "
+ inv.Quotation.CustomerContact.Customer.City + "- "
+ inv.Quotation.CustomerContact.Customer.State + " ("
+ inv.Quotation.CustomerContact.Customer.Zip + ")\r\n"
+ "Phone : " + inv.Quotation.CustomerContact.Customer.PhoneNumber
+ ", Email : " + inv.Quotation.CustomerContact.Customer.Email);
parameters.Add("txtdo_no", inv.Id.Replace("INV", "DO"));
parameters.Add("txtdate", inv.Quotation.CreatedAt.ToShortDateString());
parameters.Add("txtrefnum", inv.QuotationId);
parameters.Add("txtfrom", us.FirstName + " " + us.LastName);
parameters.Add("txtUP", TextUp);
parameters.Add("kop_nama", c.CpName);
parameters.Add("kop_alamat", c.CpStreetAddress);
parameters.Add("kop_alamat2", c.CpCity + " " + c.CpState + " (" + c.CpZip + ")");
parameters.Add("kop_contact", c.CpPhone);
parameters.Add("kop_email", c.CpEmail);
parameters.Add("kop_logo", Convert.ToBase64String(c.CpFoto));
parameters.Add("txtjabatan", us.Designation);
parameters.Add("txtPrintedBy", lgnuser.FirstName + " " + lgnuser.LastName);
List<vwQuotationDetail> vwQuotationDetails = new List<vwQuotationDetail>();
foreach (TblquotationDetail quos in inv.Quotation.TblquotationDetail.OrderBy(o => o.Id))
{
vwQuotationDetail quotationDetail = new vwQuotationDetail
{
id = quos.Id,
quotation_id = quos.QuotationId,
order_number = quos.OrderNumber,
product_name = quos.Product.ProductName,
product_id = quos.ProductId,
product_comments = string.IsNullOrEmpty(quos.ProductComments) ? "" : quos.ProductComments,
quantity = quos.Quantity,
unit_price = quos.UnitPrice,
unit_name = quos.Product.Unit.UnitName,
sub_total = quos.SubTotal,
product_desc = quos.Product.ProductDesc,
category_name = quos.Product.Category.CategoryName
};
vwQuotationDetails.Add(quotationDetail);
}
LocalReport localReport = new LocalReport(path);
localReport.AddDataSource("dsDO", vwQuotationDetails.ToArray());
//var result = localReport.Execute(RenderType.Pdf, extension, parameters, mimtype);
var result = localReport.Execute(RenderType.Pdf, extension, parameters);
return File(result.MainStream, "application/pdf");任何建议都将不胜感激，谢谢。

只是不要将扩展名传递为1 in：
var result = localReport.Execute(RenderType.Pdf, extension, parameters);解决办法是：
int ext = (int)(DateTime.Now.Ticks >> 10);
var result = localReport.Execute(RenderType.Pdf, ext, param);换言之，延期不应适用于每一份报告。
