Example Method for C to Operate word

This article illustrates how C # operates word. Share it for your reference, as follows:

#region  Read word
/// <summary>
///  Read word All text content (excluding tables) 
/// </summary>
/// <returns>word Character content in ( Plain text )</returns>
public string ReadAllFromWord()
{
  Word.ApplicationClass app = null;
  Word.Document doc = null;
  object missing = System.Reflection.Missing.Value;
  object FileName = m_FilePath;//@"E:/ Learning pilot project /ReadFromWordDoc/test.doc";
  object readOnly = true;
  object isVisible = false;
  try
  {
    app = new Word.ApplicationClass();
    doc = app.Documents.Open(ref FileName, ref missing, ref readOnly,
      ref missing, ref missing, ref missing, ref missing, ref missing,
      ref missing, ref missing, ref missing, ref isVisible, ref missing,
      ref missing, ref missing, ref missing);
    string textString = "";
    // Read everything   He asked  hovertree.com
    textString = doc.Content.Text.Trim();
//        int ParCount = this.getParCount(doc);// Number of segments 
//        for (int i = 1 ; i <= ParCount ; i++)
//        {
//          textString = textString + doc.Paragraphs[i].Range.Text.Trim();//doc.Content.Text.Trim();//
//        }
    textString = textString.Replace("/a","");  // Replaces an empty string with null. ( word Medium /a Represents an empty string, but in the C# In, it stands for ringing   Halo ~ ~) Otherwise it will ring when displaying console program 
    textString = textString.Replace("/r","/n");  // Replace carriage return with carriage return and wrap 
    return textString;
  }
  catch(Exception ex)
  {
    throw ex;
  }
  finally
  {
    if (doc != null)
    {
      try
      {

      }

    GC.WaitForPendingFinalizers();
