Create a new windows application project and add a button to it.
On click of that button, we will create a new document(word) and write a simple Hello World text in it.
To create a word document using C# we need to first reference the following DLL(com)
After adding reference, add this directive
using Microsoft.Office.Interop.Word;
Put this code on button click
private void button1_Click(object sender, EventArgs e)
{
object missing = System.Reflection.Missing.Value;
object Visible=true;
object start1 = 0;
object end1 = 0;
ApplicationClass WordApp = new ApplicationClass();
Document adoc = WordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing);
Range rng = adoc.Range(ref start1, ref missing);
try
{
rng.Font.Name = “Georgia”;
rng.InsertAfter(“Hello World!”);
object filename = @”D:\MyWord.doc”;
adoc.SaveAs(ref filename, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
WordApp.Visible = true;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
The easiest way to write code for office interoperability is to make use of VBA code.
Say you want to insert a picture in a word document what you can do is
open the word document – Go to Tools ->Macro-> Record New Macro
Now click on insert menu and insert the picture. Stop the recording, again go to Macro -Macros-> Select your Macro and click on edit
You will find the vba code over there
Sub Macro1()
Selection.InlineShapes.AddPicture FileName:= _
“C:\Documents and Settings\nishantr1\My Documents\My Pictures\untitled.bmp” _
, LinkToFile:=False, SaveWithDocument:=True
End Sub
Now to write the same code in c# you will do something like this
Range rngPic = adoc.Tables[1].Range;
rngPic.InlineShapes.AddPicture(@”C:\anne_hathaway.jpg”, ref missing, ref missing, ref missing);

If you use COM on server side (e.g. ASP.NET) you would probably have problems like this: http://support.microsoft.com/kb/257757.
You can try out this library http://flexdoc.codeplex.com/ which is free or some good but affordable third party like http://www.docentric.com.

You can create word document using c# language with this C# Libray for Word , it can create, edit, read or even convert your word documents to many other formats. I hope it will solve everyone’s problem who is having trouble creating word file in c#.

Great post!! But in my situation ,Microsoft Office is not allowed to be installed on either developer or client machine, so I can’t use Mircrosoft.Word.Object Library in my project. Anyway, I found C# Word component very helpful in creating/editing Word file without MS Automation.
