通常情況下，Microsoft word只支持添加一個文本水印到Word文檔。該文將介紹如何使用Spire.Doc for .NET 在Word文檔中頁眉中添加藝術字模擬實現Word文檔中多行文字水印效果。

C#

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;

namespace WordWatermark
{
    class Program
    {
        static void Main(string[] args)
        {
            //加載示例文檔
            Document doc = new Document();
            doc.LoadFromFile("Sample.docx");

            //添加藝術字并設置大小
            ShapeObject shape = new ShapeObject(doc,ShapeType.TextPlainText);
            shape.Width = 60;
            shape.Height = 20;

            //設置藝術字文本內容、位置及樣式
            shape.VerticalPosition = 30;
            shape.HorizontalPosition = 20;
            shape.Rotation = 315;
            shape.WordArt.Text = "內部使用";

            shape.FillColor = System.Drawing.Color.Red;
            shape.StrokeColor = System.Drawing.Color.Gray;

            Section section;
            HeaderFooter header;
           for (int n = 0; n < doc.Sections.Count; n++) { section = doc.Sections[n]; //獲取section的頁眉 header = section.HeadersFooters.Header; Paragraph paragraph1; for (int i = 0; i < 3; i++) { //添加段落到頁眉 paragraph1 = header.AddParagraph(); for (int j = 0; j < 4; j++) { //復制藝術字并設置多行多列位置 shape = (ShapeObject)shape.Clone(); shape.VerticalPosition = 50 + 150 * i; shape.HorizontalPosition=20 + 160 * j; paragraph1.ChildObjects.Add(shape); } } } //保存文檔 doc.SaveToFile("result.docx", FileFormat.Docx2013); System.Diagnostics.Process.Start("result.docx"); } } }

VB.NET

Class Program
    Private Shared Sub Main(ByVal args As String())
        Dim doc As Document = New Document()
        doc.LoadFromFile("Sample.docx")
        Dim shape As ShapeObject = New ShapeObject(doc, ShapeType.TextPlainText)
        shape.Width = 60
        shape.Height = 20
        shape.VerticalPosition = 30
        shape.HorizontalPosition = 20
        shape.Rotation = 315
        shape.WordArt.Text = "內部使用"
        shape.FillColor = System.Drawing.Color.Red
        shape.StrokeColor = System.Drawing.Color.Gray
        Dim section As Section
        Dim header As HeaderFooter

        For n As Integer = 0 To doc.Sections.Count - 1
            section = doc.Sections(n)
            header = section.HeadersFooters.Header
            Dim paragraph1 As Paragraph

            For i As Integer = 0 To 3 - 1
                paragraph1 = header.AddParagraph()

                For j As Integer = 0 To 4 - 1
                    shape = CType(shape.Clone(), ShapeObject)
                    shape.VerticalPosition = 50 + 150 * i
                    shape.HorizontalPosition = 20 + 160 * j
                    paragraph1.ChildObjects.Add(shape)
                Next
            Next
        Next
        doc.SaveToFile("result.docx", FileFormat.Docx2013)
    End Sub
End Class
