下面的例子演示了如何使用XtraReport将报表导出为MHT格式。

C#

using System.Drawing;
using System.Diagnostics;
using DevExpress.XtraPrinting;
using DevExpress.XtraReports.UI;
// ...

private void button1_Click(object sender, EventArgs e)
{
    // A path to export a report.
    string reportPath = "c:\\Test.mht";

    // Create a report instance.
    XtraReport1 report = new XtraReport1();

    // Get its MHT export options.
    MhtExportOptions mhtOptions = report.ExportOptions.Mht;

    // Set MHT-specific export options.
    mhtOptions.CharacterSet = "UTF-8";
    mhtOptions.RemoveSecondarySymbols = false;
    mhtOptions.Title = "Test Title";

    // Set the pages to be exported, and page-by-page options.
    mhtOptions.ExportMode = HtmlExportMode.SingleFilePageByPage;
    mhtOptions.PageRange = "1, 3-5";
    mhtOptions.PageBorderColor = Color.Blue;
    mhtOptions.PageBorderWidth = 3;

    // Export the report to MHT.
    report.ExportToMht(reportPath);

    // Show the result.
    StartProcess(reportPath);
}

// Use this method if you want to automaically open
// the created MHT file in the default program.
public void StartProcess(string path)
{
    Process process = new Process();
    try
    {
        process.StartInfo.FileName = path;
        process.Start();
        process.WaitForInputIdle();
    }
    catch { }
}
