C# 添加Word水印（文本水印、图片水印）

1、1.添加Word文本水印

【C#】

using Spire.Doc;

using Spire.Doc.Documents;

using System.Drawing;

namespace Text_Watermark

{

    class Program

    {

        static void Main(string[] args)

        {

            //新建一个Document类对象，并加载需要添加水印的Word文档

            Document doc = new Document();

            doc.LoadFromFile("Test.docx");

            //新建一个TextWatermark对象，设置文本水印字样

            TextWatermark txtWatermark = new TextWatermark();

            txtWatermark.Text = "Internal Use Only";

            //设置文本水印字体大小、颜色和文本排列方式

            txtWatermark.FontSize = 45;

            txtWatermark.Color = Color.Green;

            txtWatermark.Layout = WatermarkLayout.Diagonal;

            //将文本应用到Word文档水印

            doc.Watermark = txtWatermark;

            //保存并打开文档

            doc.SaveToFile("Text_Watermark.docx",FileFormat.Docx2013);

            System.Diagnostics.Process.Start("Text_Watermark.docx");

        }

    }

}

2、2. 添加Word图片水印

【C#】

using Spire.Doc;

using Spire.Doc.Documents;

namespace Add_Watermark_To_Word

{

    class Program

    {

        static void Main(string[] args)

        {

            //新建一个Document类对象，并加载需要添加水印的Word文档

            Document doc = new Document();

            doc.LoadFromFile("Test.docx");

            //初始化PictureWatermark类实例，加载作为水印的图片

            PictureWatermark picture = new PictureWatermark();

            picture.Picture = System.Drawing.Image.FromFile("wto.jpg");

            //设置图片大小，并将图片设置成水印

            picture.Scaling = 50;

            doc.Watermark = picture;

            //保存并打开文档

            doc.SaveToFile("Image_Watermark.docx",FileFormat.Docx2013);

            System.Diagnostics.Process.Start("Image_Watermark.docx");

        }

    }

}
