rdlc报告winforms 2015内存泄漏 [英] rdlc report winforms 2015 memory leak

问题描述

我正在使用  .rdlc   report我的.NET 4.5 Framework中
。

I'm currently working on windows application with a .rdlc report within my .NET 4.5 Framework.

一切正常，但对于每个PDF，内存增加大约0.5-1 MB :(我已创建一个循环关于录制PDF的整个逻辑在哪里，我正在做一些接下来的事情。

Everything works well but for every PDF the memory increases about 0.5-1 MB :( I've created a loop where is the whole logic about recording PDF and I'm doing some of next things.

foreach (var bill in billsForPDF)
{
    //...
    this.newBillsTableAdapter.Fill(this.XXXDataSet.newBills, bill.BillNumber)
    //...
    contractBindingSource.DataSource = bill.contract;
    //...
    rptViewerBill.LocalReport.SetParameters(Adresa);
    //....
    rptViewerBill.RefreshReport();
    //...
    var pages = new List<byte[]>();
    var xxx = rptViewerBill.LocalReport.Render("PDF");
    pages.Add(xxx);

    PdfDocument docX;
    PdfDocument fulldocX = new PdfDocument();

    foreach (var item in pages)
    {
        var PDFstream = new MemoryStream(item);
        docX = PdfReader.Open(PDFstream, PdfDocumentOpenMode.Import);
        CopyPages(docX, fuldocX);
    }
    fulldocX.Save(@"C:..."+bill.billNumber.ToString()+".pdf");
    /*here i'm tried almost everything with GC and disposing LocalReport, clear, null...but nothing works */    
}

比尔 .rdlc   I
有一个expr like =

In Bill.rdlc I have an expr like =

"Bill number: " & First(Fields!billNumber.Value, "DataSet1")"

有人可以帮忙吗？
