different format into one single line Interop.word

Question

I\'ve been trying to figure out how to insert 2 different formats into the same paragraph using interop.word in c# like this:

hello planet earth her

I know this is an old thread, but I thought I'd post here anyway for those that come across it via Google (like I did). I got most of the way to a solution with krillgar's approach, but I had trouble because some of my text contains newlines. Accordingly, this modification worked best for me:

private void WriteText(string text)
    {
        var para = doc.Content.Paragraphs.Add();
        var start = para.Range.Start;
        var end = para.Range.Start + text.IndexOf(":");
        para.Range.Text = text;
        para.Range.Font.Bold = 0;
        para.Range.InsertParagraphAfter();

        if(text.Contains(":")){
            var rngBold = doc.Range(start, end);
            rngBold.Bold = 1;
        }
    }

The key difference is that I calculate start and end earlier in the function. I can't quite put my finger on it, but I think if your new text has newlines in it, the later calculation of start/end messes something up.

And obviously my solution is intended for text with the format:

Label: Data

where Label is to be bolded.
