安装wps
创建.net core控制项目
添加com引用，搜索wps
准备word，名字叫001.docx
word转pdf
编写代码
namespace WPSStu01
{
internal class Program
{
static void Main(string[] args)
{
Console.WriteLine("转化开始");
var inputFile = "001.docx";
var outputFile = "001.pdf";
WordExportAsPdf(inputFile, outputFile);
Console.WriteLine("转化成功");
Console.ReadKey();
}
///
/// 转换为pdf文件，适合（.doc、.docx、.mht、.htm文件类型）
///
///
///
///
public static string WordExportAsPdf(string fileName, string outputFileName)
{
string isSucceed = "OK";
Word.WdExportFormat fileFormat = Word.WdExportFormat.wdExportFormatPDF;
Word.Application wordApp = null;
if (wordApp == null) wordApp = new Word.Application();
Word._Document wordDoc = null;
try
{
wordDoc = wordApp.Documents.Open(fileName, false, true);
wordDoc.ExportAsFixedFormat(outputFileName, fileFormat);
}
catch (Exception ex)
{
isSucceed = ex.Message;
}
finally
{
if (wordDoc != null)
{
wordDoc.Close(false);
wordDoc = null;
}
if (wordApp != null)
{
wordApp.Quit(false);
wordApp = null;
}
}
return isSucceed;
}
}
}
启动项目报错
选择一下32位程序
发现还是不行，最后换成.net framework 4.8的控制台项目
添加dll的引用,dll需要去安装的wps里面查找
Console.WriteLine("转化开始");
var exePath = System.AppDomain.CurrentDomain.BaseDirectory;
var inputFile = Path.Combine(exePath, "001.docx");
var outputFile = Path.Combine(exePath, "001.pdf");
WordExportAsPdf(inputFile, outputFile);
Console.WriteLine("转化成功");
Console.ReadKey();
asp.net core也可以问题根本原因是路径的问题，不能些相对路径，必须绝对路径
excel转pdf
////// Excel转换为pdf文件 /// /// /// /// public static string ExcelExportAsPdf(string fileName, string outputFileName) { string isSucceed = "OK"; Excel.Application excelApp = null; if (excelApp == null) excelApp = new Excel.Application(); Excel.Workbook workBook = null; try { workBook = excelApp.Workbooks.Open(fileName, false, true); workBook.ExportAsFixedFormat(Excel.XlFixedFormatType.xlTypePDF,outputFileName); } catch (Exception ex) { isSucceed = ex.Message; } finally { if (workBook != null) { workBook.Close(false); workBook = null; } if (excelApp != null) { excelApp.Quit(); excelApp = null; } } return isSucceed; }
调用
Console.WriteLine("转化开始");
var exePath = System.AppDomain.CurrentDomain.BaseDirectory;
var inputFile = Path.Combine(exePath, "002.xls");
var outputFile = Path.Combine(exePath, "002.pdf");
ExcelExportAsPdf(inputFile, outputFile);
Console.WriteLine("转化成功");
Console.ReadKey();
ppt转pdf
////// PPT转换为pdf文件 /// /// /// /// public static string PptExportAsPdf(string fileName, string outputFileName) { string isSucceed = "OK"; PowerPoint.Application pptApp = null; if (pptApp == null) pptApp = new PowerPoint.Application(); PowerPoint.Presentation presentation = null; try { presentation = pptApp.Presentations.Open(fileName); presentation.ExportAsFixedFormat(outputFileName,PowerPoint.PpFixedFormatType.ppFixedFormatTypePDF); } catch (Exception ex) { isSucceed = ex.Message; } finally { if (pptApp != null) { presentation.Close(); pptApp = null; } if (pptApp != null) { pptApp.Quit(); pptApp = null; } } return isSucceed; }
调用
Console.WriteLine("转化开始");
var exePath = System.AppDomain.CurrentDomain.BaseDirectory;
var inputFile = Path.Combine(exePath, "003.pptx");
var outputFile = Path.Combine(exePath, "003.pdf");
PptExportAsPdf(inputFile, outputFile);
Console.WriteLine("转化成功");
Console.ReadKey();
