How to keep text formatting when transferring from richTextBox to Word?
using Word = Microsoft.Office.Interop.Word;

Word.Application wordApp = new Word.Application();

wordApp.Visible = true;

Answer 1

As mentioned above, copy with the mouse and everything will turn out.
If you want to understand, see the description at the link, the receiver program usually selects the oldest option from the clipboard or offers options on how to paste.
https://docs.microsoft.com/en-us/windows/win32/dat...

for (int i = 0; i < foundList.Count; i++)
{
    oPara[i] = oDoc.Content.Paragraphs.Add();
    string tempS = foundList[i].Paragraph;
    tempS = tempS.Replace("\\pard", "");
    tempS = tempS.Replace("\\par", "");
    Clipboard.SetText(tempS, TextDataFormat.Rtf);
    oPara[i].Range.InsertParagraphAfter();
    oPara[i].Range.Paste();
    oPara[i].KeepTogether = -1;
    oPara[i].Range.Font.Size = 10;
    oPara[i].Range.Font.Name = "Arial";
}

An easy way is to copy-paste and the Word will figure it out there. Otherwise, you need to recreate all the attributes of a paragraph, word, character.
