Setting com iterop boolean value in C#

[ntlpjc]

I'm busy using the Word-inerop interface to search a Word document, but get an Error when trying to search for all bold text.

The code looks like this:
Microsoft.Office.Interop.Word.ApplicationClass vk_word_app = new Microsoft.Office.Interop.Word.ApplicationClass();

object vk_read_only = false;
object vk_visible = true;
object vk_false = false;
object vk_true = true;
object vk_dynamic = 2;
object vk_replaceMethode = WdReplace.wdReplaceAll;
int vk_bold = 1;

vk_word_app.Selection.Find.ClearFormatting();
vk_word_app.Selection.Find.Font.Bold = vk_bold;


And it trought an exception when trying to set the Bold property for searching:
Exception reads:
"Object reference not set to an instance of an object."

Which line is reported for the exception?

Welcome to TSDN. Did you miss the ; after Microsoft.Office.Interop.Word.ApplicationClass vk_word_app = new?

Welcome to TSDN. Did you miss the ; after Microsoft.Office.Interop.Word.ApplicationClass vk_word_app = new?

The statement seems to be covering two lines

     Microsoft.Office.Interop.Word.ApplicationClass vk_word_app = new Microsoft.Office.Interop.Word.ApplicationClass(); 

Perhaps they should do a
using Microsoft.Office.Word; or whatever it is to make their code lines shorter and more readable.
