C#實(shí)現(xiàn)給Word每一頁設(shè)置不同文字水印的方法詳解
Word中設(shè)置水印時(shí),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(shí),會(huì)對(duì)所有頁面都設(shè)置成統(tǒng)一效果,如果需要對(duì)每一頁或者某個(gè)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(duì)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(gè)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(duì)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(diǎn)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(diǎn)擊“引用”,“管理NuGet包”,然后搜索“Spire.Doc”,點(diǎn)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(tái)安裝。
Install-Package Spire.Doc -Version 10.1.14
代碼示例
給每頁添加文字水印時(shí),可參考如下步驟:
- 創(chuàng)建Document類的對(duì)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(duì)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(duì)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(duì)應(yīng)的節(jié),然后參考上述用到的方法來添加即可。
