如何实现下旬在C＃中的Microsoft.Office.Interop.Word约束力？

问题描述

我想实现下面的代码线，使用早期绑定后期绑定。我如何在C＃中实现呢？

当我删除的Microsoft.Office.Interop.Word参考，我得到了一些错误，这是在评论在下面的代码中提到。
Folloowing是我使用转换Word文档为PDF的代码。

 键入wordType = Type.GetTypeFromProgID（ Word.Application）; 
 
动感字= Activator.CreateInstance（wordType）; 
 
 
对象oMissing = System.Reflection.Missing.Value; 
 
 
 DirectoryInfo的dirInfo =新的DirectoryInfo（@\\server\folder）; 
 FileInfo的wordFile =新的FileInfo（文件名）; 
 
 Word.Visible = FALSE; 
 Word.ScreenUpdating = FALSE; 
 
目标文件名=（对象）wordFile.FullName; 
 
 
 VAR DOC = Word.Documents.Open（REF文件名）; 
 doc.Activate（）; 
 
对象outputFileName = wordFile.FullName.Replace（DOC，.PDF）; 
 
 / *获得一个错误WdSaveFor​​mat * / 
对象FILEFORMAT = WdSaveFor​​mat.wdFormatPDF; 
 
 
 
 doc.SaveAs（REF outputFileName，裁判FILEFORMAT）; 
 
 
 
 / *获得一个错误WdSaveOptions * / 
的SaveChanges对象= WdSaveOptions.wdDoNotSaveChanges; 
 
 / *获得一个错误_document * / 
（（_document）DOC）.Close（REF的SaveChanges）; 
 DOC = NULL; 
 
 
 Word.Quit（）; 
 
 
 MessageBox.Show（转换成功）; 
  

解决方案

做了以下变化时，其现在工作的罚款。

 键入wordType = Type.GetTypeFromProgID（Word.Application）; 
 
动感字= Activator.CreateInstance（wordType）; 
 
 
对象oMissing = System.Reflection.Missing.Value; 
 
 
 DirectoryInfo的dirInfo =新的DirectoryInfo（@\\server\folder）; 
 FileInfo的wordFile =新的FileInfo（文件名）; 
 
 Word.Visible = FALSE; 
 Word.ScreenUpdating = FALSE; 
 
目标文件名=（对象）wordFile.FullName; 
 
 VAR DOC = Word.Documents.Open（REF文件名）; 
 doc.Activate（）; 
 
对象outputFileName = wordFile.FullName.Replace（DOC，.PDF）; 
 
 / *在WdSaveFor​​mat枚举，17是pdf格式的值* / 
对象FILEFORMAT = 17; 
 
 
 doc.SaveAs（REF outputFileName，裁判FILEFORMAT）; 
 
 /在WdSaveOptions枚举，0是不保存未决更改* / 
的SaveChanges对象= 0。 
 
 doc.Close（REF的SaveChanges）; 
 DOC = NULL; 
 
 Word.Quit（）; 
 
 MessageBox.Show（转换成功）; 
  

I want to achieve late binding for the following lines of code which are using early binding. How can I achieve it in C#?

When I removed Microsoft.office.interop.word reference, I am getting some errors, which are mentioned in the comments in following code.Folloowing is the code I am using to convert a word document to pdf.

    Type wordType = Type.GetTypeFromProgID("Word.Application");

        dynamic Word = Activator.CreateInstance(wordType);


        object oMissing = System.Reflection.Missing.Value;


        DirectoryInfo dirInfo = new DirectoryInfo(@"\\server\folder");
        FileInfo wordFile = new FileInfo(fileName);

        Word.Visible = false;
        Word.ScreenUpdating = false;

        Object filename = (Object)wordFile.FullName;


        var doc = Word.Documents.Open(ref filename);
        doc.Activate();

        object outputFileName = wordFile.FullName.Replace(".doc", ".pdf");

    /*Getting an error in WdSaveFormat */ 
        object fileFormat = WdSaveFormat.wdFormatPDF;



        doc.SaveAs(ref outputFileName, ref fileFormat);



        /*Getting an error in WdSaveOptions */       
        object saveChanges = WdSaveOptions.wdDoNotSaveChanges;

    /*Getting an error in _Document*/ 
        ((_Document)doc).Close(ref saveChanges);
        doc = null;


        Word.Quit();


        MessageBox.Show("Successfully converted");

解决方案

Made the following changes, Its working fine now.

    Type wordType = Type.GetTypeFromProgID("Word.Application");

    dynamic Word = Activator.CreateInstance(wordType);


    object oMissing = System.Reflection.Missing.Value;


    DirectoryInfo dirInfo = new DirectoryInfo(@"\\server\folder");
    FileInfo wordFile = new FileInfo(fileName);

    Word.Visible = false;
    Word.ScreenUpdating = false;

    Object filename = (Object)wordFile.FullName;

    var doc = Word.Documents.Open(ref filename);
    doc.Activate();

    object outputFileName = wordFile.FullName.Replace(".doc", ".pdf");

/*in the WdSaveFormat enum, 17 is the value for pdf format*/ 
    object fileFormat = 17;


    doc.SaveAs(ref outputFileName, ref fileFormat);

 /in the   WdSaveOptions enum, 0 is for Do not save pending changes.*/
    object saveChanges = 0;

    doc.Close(ref saveChanges);
    doc = null;

    Word.Quit();

    MessageBox.Show("Successfully converted");
