Word中設(shè)置水印時，可使用預(yù)設(shè)的文字或自定義文字設(shè)置為水印效果，但通常添加水印效果時，會對所有頁面都設(shè)置成統(tǒng)一效果，如果需要對每一頁或者某個頁面設(shè)置不同的水印效果，則可以參考本文中的方法。下面，將以C# 代碼為例，對Word每一頁設(shè)置不同的文字水印效果作詳細(xì)介紹。

方法思路

在給Word每一頁添加文字水印前，首先需要在Word文檔每一頁正文的最后一個字符后面插入“連續(xù)”分節(jié)符，然后在每一節(jié)的頁眉段落里添加藝術(shù)字形狀，并設(shè)置形狀大小、對齊方式等。最后保存文檔。

dll引用

方法1

在程序中引入Spire.Doc.dll文件；將Spire.Doc for .NET下載到本地，解壓，找到BIN文件夾下的Spire.Doc.dll。然后在Visual Studio中打開“解決方案資源管理器”，鼠標(biāo)右鍵點擊“引用”，“添加引用”，將本地路徑BIN文件夾下的dll文件添加引用至程序。

方法2

通過NuGet安裝?？赏ㄟ^以下2種方法安裝：

1.可以在Visual Studio中打開“解決方案資源管理器”，鼠標(biāo)右鍵點擊“引用”，“管理NuGet包”，然后搜索“Spire.Doc”，點擊“安裝”。等待程序安裝完成。

2.將以下內(nèi)容復(fù)制到PM控制臺安裝。

Install-Package Spire.Doc -Version 10.1.14

代碼示例

給每頁添加文字水印時，可參考如下步驟：

創(chuàng)建Document類的對象，并通過LoadFromFile(string fileName)方法加載Word文檔。
通過Document.Sections[]屬性獲取指定節(jié)。
通過HeadersFooters.Header屬性獲取頁眉，HeaderFooter.AddParagraph()方法添加段落到頁眉。
創(chuàng)建ShapeObject類的對象，并傳入?yún)?shù)設(shè)置形狀類型為TextPlainText類型的藝術(shù)字。并調(diào)用方法設(shè)置藝術(shù)字樣式，如藝術(shù)字高度、寬度、旋轉(zhuǎn)、顏色、對齊方式等。
使用DocumentObjectCollection.Add(IDocumentObject)方法將藝術(shù)字添加到段落。
最后，通過Document.SaveToFile(string fileName, FileFormat fileFormat)方法保存文檔。

不同頁面中設(shè)置不一樣的文字水印效果，只需要獲取該頁面對應(yīng)的節(jié)，然后參考上述用到的方法來添加即可。
