Often there is a need to read word file contents, so by considering that requirement I decided to write the article. Let's learn step-by-step how to read a word file and display its
content in a Textbox.
The most common scenarios are as follows:
- To upload a resume and show the contents in a TextBox as summary.
- Save that resume contents into the database so later on it is useful for CV or resume parsing.
- In a blog or community website to upload file contents directly
into the editor so it becomes faster to edit contents and save it.
Now let us see the preceding explanation by creating a sample web application as follows:
- "Start" - "All Programs" - "Microsoft Visual Studio"
- "File" - "New WebSite" - "C#" - "Empty WebSite" (to avoid adding a master page).
- Provide the web site a name such as "ReadWordFilesInFillTextBox" or another as you wish and specify the location.
- Then right-click on the Solution Explorer and select "Add New Item" and Add Web Form.
- Drag and drop two Buttons, a Fileuploader and TextBox control onto the <form> section of the Default.aspx page
- Set TextBox text mode to multiline.
Now the default.aspx page source code will looks as follows.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<body bgcolor="navy">
<form id="form2" runat="server">
<div style="color: White;">
<h4>

<br />
<table width="100%">
<tr>
<td>
<asp:TextBox ID="TextBox1" TextMode="MultiLine" runat="server" Height="142px" Width="380px"></asp:TextBox><br />
</td>
</tr>
</table>
<br />
<table>
<tr>
<td>
<asp:FileUpload ID="FileUpload1" runat="server" />
</td>
<td>
<asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="btnUpload_Click" />
</td>
<td>
<asp:Button ID="Button1" runat="server" Text="Clear" OnClick="Button1_Click" />
</td>
</tr>
</table>
</div>
</form>
</body>
</html>
Now
add the reference for Microsoft.Office.Interop by right-clicking the
Solution Explorer to handle the Word file related process. I hope you
have done that. The following namespaces are required to work with
operations related to Word files:
using System.IO;
using Microsoft.Office.Interop.Word;
using System.Text;
Now double-click on the upload button and write the following code:
protected void btnUpload_Click(object sender, EventArgs e)
{
//createting the object of application class
Application Objword = new Application();
//creating the object of document class
Document objdoc = new Document();
//get the uploaded file full path
dynamic FilePath = Path.GetFullPath(FileUpload1.PostedFile.FileName);
//pass the optional (missing) parameter to API
dynamic NA = System.Type.Missing;
//open Word file document
objdoc = Objword.Documents.Open
(ref FilePath, ref NA, ref NA, ref NA, ref NA,
ref NA, ref NA, ref NA, ref NA,
ref NA, ref NA, ref NA, ref NA,
ref NA, ref NA, ref NA
);
//creating the object of string builder class
StringBuilder sb = new StringBuilder();
for (int Line = 0; Line < objdoc.Paragraphs.Count; Line++)
{
string Filedata = objdoc.Paragraphs[Line + 1].Range.Text.Trim();
if (Filedata != string.Empty)
{
//Append word files data to stringbuilder
sb.AppendLine(Filedata);
}
}
//closing document object
((_Document)objdoc).Close();
//Quit application object to end process
((_Application)Objword).Quit();
//assign stringbuilder object to show text in textbox
TextBox1.Text =Convert.ToString(sb);
}
Now double-click on the reset button and write the following code:
protected void Button1_Click(object sender, EventArgs e)
{
TextBox1.Text =string.Empty;
}
The entire code of the default.aspx.cs will look as in the following:
using System;
using System.IO;
using Microsoft.Office.Interop.Word;
using System.Text;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnUpload_Click(object sender, EventArgs e)
{
//createting the object of application class
Application Objword = new Application();
//creating the object of document class
Document objdoc = new Document();
//get the uploaded file full path
dynamic FilePath = Path.GetFullPath(FileUpload1.PostedFile.FileName);
//pass the optional (missing) parameter to API
dynamic NA = System.Type.Missing;
//open Word file document
objdoc = Objword.Documents.Open
(ref FilePath, ref NA, ref NA, ref NA, ref NA,
ref NA, ref NA, ref NA, ref NA,
ref NA, ref NA, ref NA, ref NA,
ref NA, ref NA, ref NA
);
//creating the object of string builder class
StringBuilder sb = new StringBuilder();
for (int Line = 0; Line < objdoc.Paragraphs.Count; Line++)
{
string Filedata = objdoc.Paragraphs[Line + 1].Range.Text.Trim();
if (Filedata != string.Empty)
{
//Append word files data to stringbuilder
sb.AppendLine(Filedata);
}
}
//closing document object
((_Document)objdoc).Close();
//Quit application object to end process
((_Application)Objword).Quit();
//assign stringbuilder object to show text in textbox
TextBox1.Text =Convert.ToString(sb);
}
protected void Button1_Click(object sender, EventArgs e)
{
TextBox1.Text =string.Empty;
}
}
Now run the application. The UI will look as follows:
In
the preceding UI Browse control will be used to select the files from
the physical location. On a upload button click, it will read the
uploaded Word file and show it in the TextBox. The Clear button will
clear the text box contents.
Now select the Word file and click on upload, it will show the file contents in the TextBox as follows.
Now you have seen how to read Word file contents and put it into a TextBox.
Notes
- Do a proper validation such as if it has a file or not of the File Upload control when implementing.
