如何将office文件转换成图片格式

Question

请教一下，我现在想实现一个将office文件转换成图片的功能，能不能用代码实现。

Answer 1

这个比较麻烦。

当年在某个项目中，我是采用openoffice作为中转站实现这个的。你可以借鉴一下。

Answer 2

Document doc = null;
ApplicationClass app = new ApplicationClass();
app.Visible = false;
app.AlertResponse = (short)1;
string CurrentPath = Server.MapPath("~/test1.vsd");

doc = app.Documents.OpenEx(CurrentPath, (short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visOpenCopy);//打开一个visio文件

doc.Pages[1].Export(Server.MapPath("~/test1.jpg"));//转换成jpg格式的文件 
doc.Close();
app.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(doc);
System.Runtime.InteropServices.Marshal.ReleaseComObject(app);

我在网上看到这段代码  我现在试的是word文件但是好像没有 Pages[1].Export 这个方法

Hi sl_water,

欢迎来到MSDN论坛。

如果您只是想把office文档转成图片格式，可以使用现成的office工具，Microsoft Office Document Imaging (MODI)。

Office 2003 & 2007：http://office.microsoft.com/en-us/help/about-microsoft-office-document-imaging-HP001077103.aspx 

Office 2010：http://support.microsoft.com/kb/982760 

如果希望使用代码实现，您可以参考下面的代码：

        static void Main(string[] args)
        {
            print();
            Console.WriteLine("Done");
            Console.ReadKey();
        }

        static private void print()
        {
            try
            {
                // Declaring the object variables we will need later 
                object varFileName = "E:\\Test\\test.docx";
                object varFalseValue = false;
                object varTrueValue = true;
                object varMissing = Type.Missing;

                // Create a reference to MS Word application 
                Microsoft.Office.Interop.Word._Application varWord = new
                Microsoft.Office.Interop.Word.Application();
                              
                varWord.ActivePrinter = "Microsoft Office Live Meeting 2007 Document Writer";
                // Creates a reference to a word document 
                Microsoft.Office.Interop.Word._Document varDoc =
                    varWord.Documents.Open(varFileName, ReadOnly: varFalseValue);
                  
                // Activate the document 
                varDoc.Activate();
                // Print the document 
                object PrintToFile = true;

                object OutputFileName = "E:\\test\\test.tif";
                varDoc.PrintOut(OutputFileName: OutputFileName);                   

                varDoc.Close();
                varWord.Quit();
                varDoc = null;
                varWord = null;

                GC.Collect();
                GC.WaitForPendingFinalizers();
                GC.Collect();
                GC.WaitForPendingFinalizers();
            }
            catch (Exception varE)
            {
                Console.WriteLine("Error:\n" + varE.Message, "Error message");
            }
        }
