如何以编程方式将Word文件转换为PDF？[关闭]

使用foreach循环而不是for循环-它解决了我的问题。

int j = 0;foreach (Microsoft.Office.Interop.Word.Page p in pane.Pages){    var bits = p.EnhmetaFileBits;    var target = path1 +j.ToString()+  "_image.doc";    try    {        using (var ms = new MemoryStream((byte[])(bits)))        { var image = System.Drawing.Image.FromStream(ms); var pngTarget = Path.ChangeExtension(target, "png"); image.Save(pngTarget, System.Drawing.Imaging.ImageFormat.Png);        }    }    catch (System.Exception ex)    {        MessageBox.Show(ex.Message);      }    j++;}

这是对我有用的程序的修改。它使用安装了“
另存为PDF”加载项的
Word 2007
。它在目录中搜索.doc文件，在Word中打开它们，然后将它们另存为PDF。请注意，您需要在解决方案中添加对Microsoft.Office.Interop.Word的引用。
