WordDocument.Words[_index_].Font.Bold returns -1 for Bold text. RRS feed

  • Question

  • Hello everyone.

    I use Visual Studio 2017 and .NET Framework 4.5.

    I tried to identify all words with bold font in word document. First i thought that i would get 1 for Bold, 0 for regular font, but interop word returned -1 for bold font.

    I wonder to know is this case is normal or not.

    Thank you for attention!

  • False = 0
    True = -1

    You might also need to allow for Words that contain some, but not all, characters in a bold font:
    Mixed = 9999999

  • Hi AllocatedMemory,

    Below is the testing result on my side with VS 2017.

     private void button1_Click(object sender, EventArgs e)
                word.Application page = new word.Application();
                page.Visible = true;
                word.Document doc = null;
                    doc = page.Documents.Open(@"C:\Users\v-padee\Desktop\sample.docx");
                    if (doc != null)
                        textBox1.Text = doc.Words[1].Bold.ToString();


    I hope it clears your doubt.
