将`Window`保存为pdf

Question

我有一个类ReportViewerView，它继承了Window class。我想将此类的内容保存为pdf文件。

我已经可以将该类打开为ShowDialog()的窗口，一旦打开该窗口，就可以选择保存为正常工作的Acrobat（pdf）文件。但是，我想保存该窗口的内容 ，不用 首先打开一个对话框。我拥有打开此窗口所需的所有数据，我想立即将其保存到预定的文件位置，无需任何用户输入。我怎么能这样做？

public void SaveReport(MyClass report, string title)
{
    ReportViewerView reportViewer = new ReportViewerView(report, title);
    //reportViewer.ShowDialog();

    // is it even possible to make this a byte[] ?
    byte[] reportBytes = Convert.FromBase64String(reportViewer.ToString());
    System.IO.File.WriteAllBytes("C:\\Temp\\Test_Save.pdf", reportBytes);

    //Maybe a FileStream?
    using (FileStream fs = new FileStream("C:\\Temp\\Test_Save.pdf", FileMode.Open))
    {  // Maybe not a TextReader... what would a 'Window' use?
        using (System.Xml.XmlTextReader xmlReader = new System.Xml.XmlTextReader(fs))
        {
            reportViewer.Serialize(xmlReader); // cannot serialize anyway
        }
    }
}

类ReportViewerView是我的遗留代码，与Telerik类ReportViewer相关。类MyClass是继承自Telerik.Reporting.Report的遗留代码。我怀疑Windows课程是我的答案，但如果它有帮助，ReportViewerView.xaml.cs：

public partial class ReportViewerView : Window
{
    public ReportViewerView(MyClass reportDoc, string title)
    {
        InitializeComponent();

        InstanceReportSource rs = new InstanceReportSource();
        rs.ReportDocument = reportDoc;
        this.reportViewer1.ReportSource = rs;
        this.Title = title;
    }
}

课程MyClass有点笨重，可以完全复制/粘贴，但它应该执行其父Telerik.Reporting.Report可以做的任何事情。这是简短版本：

partial class MyClass
{
    private void InitializeComponent()
    {
        // lot of stuff
    }

    private Telerik.Reporting.PageHeaderSection pageHeaderSection1;
    private Telerik.Reporting.DetailSection detail;
    private Telerik.Reporting.PageFooterSection pageFooterSection1;
    private Telerik.Reporting.TextBox textBox1;
    private Telerik.Reporting.TextBox TitleTB;
    private Telerik.Reporting.TextBox CustomerNameTB;
    private Telerik.Reporting.TextBox ReportDateTB;
    private string dateString
    {
        get { return DateTime.Now.ToString("g", CultureInfo.CreateSpecificCulture("en-us")); }
    }

}
