在c＃中删除/编辑word office builtindocumentproperties [英] Remove/Edit word office builtindocumentproperties in c#

问题描述

关于此代码，请求您的帮助。我正在编写一个c＃中的代码，它可以清除属性中内置的word文档，并在提供的替换时将其替换为提供的替换。基于我在microsft支持网站http://support.microsoft.com/kb/303296上在网上找到的例子，我的代码没问题，并且假设工作，因为我也没有得到任何编译错误。但是没有做我要求它做的事情，因为我没有得到任何结果。请大家，如果有人会帮助我替代或者指出我的错误，那么我真的很感激，这样我花的几周就会白白浪费。谢谢你的帮助。以下是我的代码。

  private   void  execute_Click（ object  sender，EventArgs e）
 {
 Word。申请表; 
 Word.Document dc =  new  Word.Document（）; 
 对象 bSaveChanges =  false ; 
  string  chosen_file =  ; 
 chosen_file = openFD.FileName; 
 textBox1.Text =（chosen_file）; 
  var  filter = Path.GetExtension（chosen_file）; 
 
  object  Filename = chosen_file.ToString（）; 
  if （filter ==  。doc  || filter ==  。docx）
 {
 wapp =  new  Word.Application（）; 
 wapp.Visible =  true ; 
 docword = wapp.Documents.Add（ ref 文件名，参考缺失， ref 缺失， ref 缺失）; 
 
  object  _BuiltInProperties = docword.BuiltInDocumentProperties; 
类型typeDocBuiltInProps = _BuiltInProperties.GetType（）; 
 
 removeproperty（_BuiltInProperties，typeDocBuiltInProps）;  //  传递参数 
 docword.Close（ ref  bSaveChanges， ref 缺失， ref 缺少）; 
 wapp.Quit（ ref  bSaveChanges， ref 缺失，参考缺失）; 
} 
} 
 
 私有  void  removeproperty（  object  _BuiltInProperties，Type typeDocBuiltInProps）
 {
 
  string  subjectprop =  主题; 
  string  subjectValue =  ; 
  string  companyprop =  公司; 
  string  companyvalue = txtcompany.Text; 
 
  if （clearsubject.Checked ==  true ）
 { 
 尝试 
 {
 对象 Subjectprop = typeDocBuiltInProps.InvokeMember（< span class =code-string>  Item，BindingFlags.Default | BindingFlags.GetProperty， null ，_ BuildInProperties， new   object  [] {  主题}）; 
类型typeSubjectprop = Subjectprop.GetType（）; 
 
 typeSubjectprop.InvokeMember（  Item，BindingFlags.Default | BindingFlags。 SetProperty， null ，Subjectprop， new   object  [] {subjectprop，subjectValue}）; 
 
} 
  catch （COMException）
 {
 
} 
 
} 
 
  if （resetcompany.Checked ==  true ）
 {
 尝试 
 {
 对象 Companyprop = typeDocBuiltInProps .InvokeMember（  Item，BindingFlags.Default | BindingFlags.GetProperty， null ，_ BuildInProperties， new   object  [] { 公司}）; 
类型typeCompanyprop = Companyprop.GetType（）; 
 typeCompanyprop.InvokeMember（  Item，
 BindingFlags.Default | 
 BindingFlags.SetProperty，
  null ，Companyprop，
  new   object  [] {companyprop，companyvalue}）; 
 
 
} 
  catch （COMException）
 {
 
} 
 
 
} 

解决方案

对于 C＃DOCX 文件格式，您可以使用此C# / VB.NET Word 库。



这是一个示例C＃代码：

  //  在免费模式下使用该组件。 
 ComponentInfo.SetLicense（  FREE-LIMITED-KEY）; 
 
  //  创建新的空文档。 
  var  document =  new  DocumentModel（）; 
 
  //  添加各种内置文档属性。 
 document.DocumentProperties.BuiltIn.Add（BuiltInDocumentProperty.Title， 我的文档标题）; 
 document.DocumentProperties.BuiltIn.Add（BuiltInDocumentProperty.Subject， 我的文档主题） ; 
 document.DocumentProperties.BuiltIn.Add（BuiltInDocumentProperty.Author，  John Doe）; 
 document.DocumentProperties.BuiltIn.Add（BuiltInDocumentProperty.Keywords，  keyword1，keyword2，keyword3）; 
 
  //  将文档保存到文件中。 
 document .Save（  Document.docx，SaveOptions.DocxDefault）; 
 
  //  从文件加载文档。 
文档= DocumentModel.Load（  Document.docx，LoadOptions.DocxDefault）; 
 
  //  迭代内置文档属性并将其写入Console。 
  foreach （ var  builtInProperty  in  document.DocumentProperties.BuiltIn）
 Console.WriteLine（  {0}：{1}，builtInProperty.Key，builtInProperty.Value）; 

我不知道你现在是否需要解决方案但是我做了这件事。 br />
我的代码在你的版本中也没有用。

我删除外部方法removeproperty并将所有代码放到execute_Click并且情况变好了。

Please need your help regarding this code. I am writing a code in c# that can will clear a word document built in property, and also replace it with a provided replacement where provided. Base on the example i found online in microsft support website http://support.microsoft.com/kb/303296 , my code is alright and suppose to work as i don''t get any compile error as well. but is not doing what i ask it to do as i don''t get any result. Please guys , will really appreciate it if some one will help me with an alternative or point out my error so that the weeks i spent will ruin in vain. Thanks you as you help. Below is my code.

private void execute_Click(object sender, EventArgs e)
        {
             Word.Application wapp; 
             Word.Document dc = new Word.Document() ;
 Object bSaveChanges = false;
           string chosen_file = "";
           chosen_file = openFD.FileName;
           textBox1.Text = (chosen_file);
           var filter = Path.GetExtension(chosen_file);

           object Filename = chosen_file.ToString();
           if (filter == ".doc" || filter == ".docx")
           {
               wapp = new Word.Application();
               wapp.Visible = true;
               docword = wapp.Documents.Add(ref Filename, ref missing, ref missing, ref missing);

               object _BuiltInProperties = docword.BuiltInDocumentProperties;
                Type typeDocBuiltInProps = _BuiltInProperties.GetType();

                 removeproperty(_BuiltInProperties, typeDocBuiltInProps);// pass parameter
                 docword.Close(ref bSaveChanges, ref missing, ref missing);
                 wapp.Quit(ref bSaveChanges, ref missing, ref missing);
           }
  }

 private void removeproperty(object _BuiltInProperties, Type typeDocBuiltInProps)
        {

            string subjectprop = "Subject";
            string subjectValue = "";
            string companyprop = "Company";
            string companyvalue = txtcompany.Text;

             if (clearsubject.Checked == true)
            {
                try
                {
                    Object Subjectprop = typeDocBuiltInProps.InvokeMember("Item", BindingFlags.Default | BindingFlags.GetProperty, null, _BuiltInProperties, new object[] { "Subject" });
                    Type typeSubjectprop = Subjectprop.GetType();

                    typeSubjectprop.InvokeMember("Item", BindingFlags.Default | BindingFlags.SetProperty, null, Subjectprop, new object[] { subjectprop, subjectValue  });

                }
                catch (COMException)
                {

                }

            }

       if (resetcompany.Checked == true)
            {
                try
                {
                  Object Companyprop = typeDocBuiltInProps.InvokeMember("Item", BindingFlags.Default | BindingFlags.GetProperty, null, _BuiltInProperties, new object[] { "Company" });
                    Type typeCompanyprop = Companyprop.GetType();
                    typeCompanyprop.InvokeMember("Item",
                               BindingFlags.Default |
                               BindingFlags.SetProperty,
                               null, Companyprop,
                               new object[] { companyprop, companyvalue });


                }
                 catch (COMException)
                {

                }


}

解决方案

For C# DOCX file format, you can easily add / edit / iterate over document properties using this C# / VB.NET Word library.

Here is a sample C# code:

// Use the component in free mode.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");

// Create new empty document.
var document = new DocumentModel();

// Add various built-in document properties.
document.DocumentProperties.BuiltIn.Add(BuiltInDocumentProperty.Title, "My document title");
document.DocumentProperties.BuiltIn.Add(BuiltInDocumentProperty.Subject, "My document subject");
document.DocumentProperties.BuiltIn.Add(BuiltInDocumentProperty.Author, "John Doe");
document.DocumentProperties.BuiltIn.Add(BuiltInDocumentProperty.Keywords, "keyword1, keyword2, keyword3");

// Save the document to a file.
document.Save("Document.docx", SaveOptions.DocxDefault);

// Load a document from the file.
document = DocumentModel.Load("Document.docx", LoadOptions.DocxDefault);

// Iterate over built-in document properties and write them to Console.
foreach (var builtInProperty in document.DocumentProperties.BuiltIn)
	Console.WriteLine("{0}: {1}", builtInProperty.Key, builtInProperty.Value);

I don''t know if you now need the solution but I do this thing.
My code didn''t work in your version too.
I remove external method "removeproperty" and place all code to "execute_Click" and situation became Ok.
