Programmatically Open Word Document Located in the Computer in C#

Question

I'm using WinForms. I have a form that has a button.

Goal: On button click: Open up a word document. Where the file path is hard coded into the program. I don't want the users to have to locate the word document.

Problem: I receive this error message. When I wrote my code, I get a red error line under 'Application'.

    private void button1_Click(object sender, EventArgs e)
    { 
        this.Application.Documents.Open(@"C:\Test\NewDocument.docx", ReadOnly:true)

    }

Answer 1

Instead of adding interop in your reference, you may also consider to use this:

System.Diagnostics.Process.Start(@"C:\Test\NewDocument.docx");

Answer 2

first add the dll of Microsoft.Office.Interop.Word to your references then add this:

using Microsoft.Office.Interop.Word;

and use the following code:

Application ap = new Application(); 
Document document = ap.Documents.Open(@"C:\Test\NewDocument.docx");
