最近在研究winform打印文件，需要支持word，excel，ppt，pdf，图片这几种格式，不能依赖相关软件环境，研究后决定使用Aspose套件将相关文件全部转换成pdf后打印
WrodToPDF
使用Aspose.Word
代码语言：javascript复制 //去水印
string licenseFile = "Aspose.Words.lic";
if (File.Exists(licenseFile))
{
Aspose.Words.License license = new Aspose.Words.License();
license.SetLicense(licenseFile);
}
//转换
Aspose.Words.Document doc = new Aspose.Words.Document(FileFullName);
doc.Save(SaveFileName, Aspose.Words.SaveFormat.Pdf);ExcelToPDF
使用Aspose.Cell（破解版本）
代码语言：javascript复制 //转换
Workbook excel = new Workbook(FileFullName);
excel.Save(SaveFileName, Aspose.Cells.SaveFormat.Pdf);PPTToPDF
使用Aspose.Slides
代码语言：javascript复制 //去水印
