ASP.NET VS2013 Office 转 PDF

本文适用于VS2013 项目中的Word转换为PDF、Excel转换为PDF、PPT转换为PDF

0.一种更加简单方便的方法

1.本页所用的方法在本机测试时基本不会出现问题，只是偶尔PPT转PDF失败，需要重新添加dll，但是在服务器环境就会出现各种错误，需要各种配置。

2.http://www.cnblogs.com/moonache/p/4991459.html 请参考此文，更简单实用。

1.添加Using

1.在后台添加using

using Microsoft.Office.Interop.Word;
using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Core;
using Microsoft.Office.Interop.PowerPoint;

2.添加引用

1.添加引用

3.添加代码

1.在后台添加代码

protected void Page_Load(object sender, EventArgs e)
{
    string wordSource,wordTarget,excelSource,excelTarget,pptSource,pptTarget;
    wordSource = @"E:FileDownloadExplorer意向 0.3.docx";
    wordTarget = @"E:FileDownloadExplorerW2P.pdf";
    excelSource = @"E:FileDownloadExplorerxlsx.xlsx";
    excelTarget = @"E:FileDownloadExplorerE2P.pdf";
    pptSource = @"E:FileDownloadExplorer质量月活动1509.pptx";
    pptTarget = @"E:FileDownloadExplorerP2P.pdf";


    WordToPdf(wordSource,wordTarget);
    ExcelToPdf(excelSource,excelTarget);
    PPTConvertToPDF(pptSource, pptTarget);

}

public static bool WordToPdf(string sourcePath, string targetPath)
{
    bool result = false;
    WdExportFormat wdExportFormatPDF = WdExportFormat.wdExportFormatPDF;//转换格式1.wdExportFormatPDF转换成pdf格式 2.wdExportFormatXPS转换成xps格式
    object missing = Type.Missing;
    Microsoft.Office.Interop.Word.ApplicationClass applicationClass = null;
    Document document = null;
    try
    {
        applicationClass = new Microsoft.Office.Interop.Word.ApplicationClass();
        object inputfileName = sourcePath;//需要转格式的文件路径
        string outputFileName = targetPath;//转换完成后PDF或XPS文件的路径和文件名名称
        WdExportFormat exportFormat = wdExportFormatPDF;//导出文件所使用的格式
        bool openAfterExport = false;//转换完成后是否打开
        WdExportOptimizeFor wdExportOptimizeForPrint = WdExportOptimizeFor.wdExportOptimizeForPrint;//导出方式1.wdExportOptimizeForPrint针对打印进行导出，质量较高，生成的文件大小较大。2.wdExportOptimizeForOnScreen 针对屏幕显示进行导出，质量较差，生成的文件大小较小。

        if (document != null)
        {
            document.ExportAsFixedFormat(outputFileName, exportFormat, openAfterExport, wdExportOptimizeForPrint, wdExportAllDocument, from, to, wdExportDocumentContent, includeDocProps, keepIRM, wdExportCreateWordBookmarks, docStructureTags, bitmapMissingFonts, UseISO19005_1, ref missing);
        }
        result = true;
    }
    catch
    {
        result = false;
    }
    finally
    {
        if (document != null)
        {
            document.Close(ref missing, ref missing, ref missing);
            document = null;
        }
        if (applicationClass != null)
        {
            applicationClass.Quit(ref missing, ref missing, ref missing);
            applicationClass = null;
        }
    }
    return result;
}

public static bool ExcelToPdf(string sourcePath, string targetPath)
{
    bool result = false;
    XlFixedFormatType xlTypePDF = XlFixedFormatType.xlTypePDF;//转换成pdf
    object missing = Type.Missing;
    Microsoft.Office.Interop.Excel.ApplicationClass applicationClass = null;
    Workbook workbook = null;
    try
    {
        applicationClass = new Microsoft.Office.Interop.Excel.ApplicationClass();
        string inputfileName = sourcePath;//需要转格式的文件路径
        string outputFileName = targetPath;//转换完成后PDF文件的路径和文件名名称
        XlFixedFormatType xlFixedFormatType = xlTypePDF;//导出文件所使用的格式
        XlFixedFormatQuality xlFixedFormatQuality = XlFixedFormatQuality.xlQualityStandard;//1.xlQualityStandard:质量标准，2.xlQualityMinimum;最低质量
        bool includeDocProperties = true;//如果设置为True，则忽略在发布时设置的任何打印区域。
        bool openAfterPublish = false;//发布后不打开
        workbook = applicationClass.Workbooks.Open(inputfileName, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
        if (workbook!=null)
        {
            workbook.ExportAsFixedFormat(xlFixedFormatType, outputFileName, xlFixedFormatQuality, includeDocProperties, openAfterPublish, missing, missing, missing, missing);
        }
        result = true;
    }
    catch
    {
        result = false;
    }
    finally
    {
        if (workbook != null)
        {
            workbook.Close(true, missing, missing);
            workbook = null;
        }
        if (applicationClass != null)
        {
            applicationClass.Quit();
            applicationClass = null;
        }
    }
    return result;
}

public static bool PPTConvertToPDF(string sourcePath, string targetPath)
{
   bool result;
   PpSaveAsFileType ppSaveAsFileType = PpSaveAsFileType.ppSaveAsPDF;//转换成pdf
   object missing = Type.Missing;
   Microsoft.Office.Interop.PowerPoint.ApplicationClass application = null;
   Presentation persentation = null;
   try
   {
       application = new Microsoft.Office.Interop.PowerPoint.ApplicationClass();
       persentation = application.Presentations.Open(sourcePath, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse);
       if (persentation!=null)
       {
           persentation.SaveAs(targetPath, ppSaveAsFileType, MsoTriState.msoTrue);
       }
       result = true;
   }
   catch
   {
       result = false;
   }
   finally
   {
       if (persentation != null)
       {
           persentation.Close();
           persentation = null;
       }
       if (application != null)
       {
           application.Quit();
           application = null;
       }
   }
   return result;
}

2.单独的Excel2PDF（Word2PDF同理，不过PPT2PDF就要采用上面的方法）

1.在后台添加using

using Microsoft.Office.Interop.Excel;

2.在项目中添加引用

3.添加如下代码

public static bool ExcelToPdf(string sourcePath, string targetPath)
{
    bool result = false;
    XlFixedFormatType xlTypePDF = XlFixedFormatType.xlTypePDF;//转换成pdf
    object missing = Type.Missing;
    Microsoft.Office.Interop.Excel.ApplicationClass applicationClass = null;
    Workbook workbook = null;
    try
    {
        applicationClass = new Microsoft.Office.Interop.Excel.ApplicationClass();
        string inputfileName = sourcePath;//需要转格式的文件路径
        string outputFileName = targetPath;//转换完成后PDF文件的路径和文件名名称
        XlFixedFormatType xlFixedFormatType = xlTypePDF;//导出文件所使用的格式
        XlFixedFormatQuality xlFixedFormatQuality = XlFixedFormatQuality.xlQualityStandard;//1.xlQualityStandard:质量标准，2.xlQualityMinimum;最低质量
        bool includeDocProperties = true;//如果设置为True，则忽略在发布时设置的任何打印区域。
        bool openAfterPublish = false;//发布后不打开
        workbook = applicationClass.Workbooks.Open(inputfileName, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
        if (workbook!=null)
        {
            workbook.ExportAsFixedFormat(xlFixedFormatType, outputFileName, xlFixedFormatQuality, includeDocProperties, openAfterPublish, missing, missing, missing, missing);
        }
        result = true;
    }
    catch
    {
        result = false;
    }
    finally
    {
        if (workbook != null)
        {
            workbook.Close(true, missing, missing);
            workbook = null;
        }
        if (applicationClass != null)
        {
            applicationClass.Quit();
            applicationClass = null;
        }
    }
    return result;
}

4.如果遇到”无法嵌入互操作类型“……”，请改用适用的接口“

选中项目中引入的dll，鼠标右键，选择属性，把“嵌入互操作类型”设置为False。

1.我在具体项目中使用时发现方法一种引入的DLL可以重复引用（感觉就像引用了没效果一样），而且每次关闭VS2013后重新打开编译工程都失败，都必须再重新引用一次。侥幸PPT转PDF功能用不上，最后选择了方法二。
