Sometimes we need to insert a symbol or special character in the paragraph. The article is introducing the solution to insert a symbol in Word with c# code. We will use Ä and Ë as the symbol examples to complete the process, with the help of a Word .NET API called Spire.Doc.

First we need to complete the preparatory work:

• Download the latest Spire.Doc and install it on your machine.
• Add the Spire.Doc.dll files as reference.
• Open bin folder and select the three dll files under .NET 4.0.
• Right click property and select properties in its menu.
• Set the target framework as .NET 4.
• Add Spire.Doc as namespace.

Here comes to the explanation of the code.

Step 1: Create an instance of Spire.Doc.Document.

Document document = new Document();

Step 2: Add a section.

Section section = document.AddSection();

Step 3: Add a paragraph.

Paragraph paragraph = section.AddParagraph();

Step 4: Use unicode characters to create symbol Ä.

TextRange tr = paragraph.AppendText('\u00c4'.ToString());

In fact, the following step5 and step6 are just the option according to your requirement.

Step 5: Set the color of symbol Ä.

tr.CharacterFormat.TextColor = Color.Red;

Step 6: Add symbol Ë.

paragraph.AppendText('\u00cb'.ToString());

Step 7: Save to Word file.

document.SaveToFile("sample.docx", FileFormat.Docx);

Here is the full code:

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;
namespace InsertSymbol
{

    class Program
    {
        static void Main(string[] args)
        {
            Document document = new Document();
            Section section = document.AddSection();
            Paragraph paragraph = section.AddParagraph();
            TextRange tr = paragraph.AppendText('\u00c4'.ToString());
            tr.CharacterFormat.TextColor = Color.Red;
            paragraph.AppendText('\u00cb'.ToString());
            document.SaveToFile("sample.docx", FileFormat.Docx);
        }

    }
}
