如何将Word转换为PDF

一、使用Spire组件

文件提取自Spire.Office for .NET v2.16

组件名称 组件版本

Spire.Doc.dll 5.9.23.14040

Spire.Presentation.dll 2.8.13.14040

Spire.XLS.dll 7.12.23.14040

Spire.Pdf.dll 3.9.130.14040

使用方法：请将需要用的组件连同Spire.License.dll一起添加至项目引用。PS：桌面客户端(WPF/WinForm等)调用应该没有问题，Web调用会报错，破解水平有限，请体谅。

免费下载Spire.Doc for .NET并将其转换为PDF以供个人使用或评估。 在C＃中将Word转换为PDF的整个过程可以描述为2个简单的步骤。

1.通过使用ocument.LoadFromFile（）方法声明您准备的文档和加载文档，传递给该方法的参数是文件名字符串。

2.使用document.SaveToFile（）方法将Word文档另存为PDF，传递给此方法的参数是文件名字符串和文件格式，文件格式必须为PDF格式。

全部代码：

using Spire.Doc;
using Spire.Presentation;
using Spire.Xls;
using System;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //word转PDF
            Document word = new Document();
            word.LoadFromFile(@"C:1.docx");
            word.SaveToFile("ToPdf.pdf", Spire.Doc.FileFormat.PDF);
            System.Diagnostics.Process.Start("ToPdf.pdf");

            //Excel转PDF
            Workbook xls = new Workbook();
            xls.LoadFromFile(@"C:1.xlsx");
            xls.SaveToFile("ToPdf.pdf", Spire.Xls.FileFormat.PDF);
            xls.ConverterSetting.SheetFitToPage = true;
            System.Diagnostics.Process.Start("ToPdf.pdf");

            //PPT转PDF
            Presentation ppt = new Presentation();
            ppt.LoadFromFile(@"C:1.pptx");
            ppt.SaveToFile("ToPdf.pdf", Spire.Presentation.FileFormat.PDF);
            System.Diagnostics.Process.Start("ToPdf.pdf");
        }
    }
}

二、使用Aspose组件

ASPOSE及授权

Aspose.Cells.dll 文件版本8.3

Aspose.Pdf.dll 文件版本9.8

Aspose.Slides.dll文件版本14.10

Aspose.Words.dll 文件版本14.10

全部代码：

using Aspose.Cells;
using Aspose.Slides;
using Aspose.Words;
using System;
using System.IO;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        /// <summary>
        /// PPT转PDF
        /// </summary>
        /// <param name="InPath">输入路径</param>
        /// <param name="OutPath">输出路径</param>
        public void PPT_PDF(string InPath, string OutPath)
        {
            Presentation ppt = new Presentation(InPath);
            ppt.Save(OutPath, Aspose.Slides.Export.SaveFormat.Pdf);
        }

        /// <summary>
        /// Word转PDF
        /// </summary>
        /// <param name="InPath"></param>
        /// <param name="OutPath"></param>
        public void Word_PDF(string InPath, string OutPath)
        {
            Document doc = new Document(InPath);
            doc.Save(OutPath, Aspose.Words.SaveFormat.Pdf);
        }

        /// <summary>
        /// Excel转PDF
        /// </summary>
        /// <param name="InPath"></param>
        /// <param name="OutPath"></param>
        public void Excel_PDF(string InPath, string OutPath)
        {
            Workbook excel = new Workbook(InPath);
            excel.Save(OutPath, Aspose.Cells.SaveFormat.Pdf);
        }

        private void button1_Click(object sender, System.EventArgs e)
        {
            AsposeLicenseHelper.SetCellsLicense();
            Excel_PDF(@"C:UsersPCDocumentsWeChat FilesyangbobinFileStorageFile2021-09校服费(1).xls", "ToPdf.pdf");
            System.Diagnostics.Process.Start("ToPdf.pdf");
        }
    }
}
