如何使用Open XML和c#改变单个段落或页面的方向
本文关键字：方向 单个段 改变 Open 何使用 XML | 更新日期: 2023-09-27 18:05:59
我正在使用c#和Open XML SDK生成word文档。我想改变一些段落及其包含页面的方向横向，而保持其他的纵向。
我尝试了一些解决方案，但他们没有达到我想要的，而是所有页面的方向都被改为横向除了第一个。这些解决方案包括:
-添加SectionProperties到我想要更改的段落它的横向方向:
WordprocessingDocument WordDocument = WordprocessingDocument.Open(ReportFile, true)
Paragraph paragraph = new Paragraph(new ParagraphProperties(
new SectionProperties( new PageSize()
{ Width = (UInt32Value)15840U, Height = (UInt32Value)12240U, Orient = PageOrientationValues.Landscape })));
WordDocument.MainDocumentPart.Document.Body.Append(paragraph);
-在主文档中添加一个新的Body，并在其上追加段落:
WordprocessingDocument WordDocument = WordprocessingDocument.Open(ReportFile, true)
Body body = new Body();
Paragraph paragraph = new Paragraph(new ParagraphProperties(
new SectionProperties( new PageSize()
{ Width = (UInt32Value)15840U, Height = (UInt32Value)12240U, Orient = PageOrientationValues.Landscape })));
body.Append(paragraph);
WordDocument.MainDocumentPart.Document.Append(body);
-在主文档中添加一个新的Body，并直接添加sectionproperties:
WordprocessingDocument WordDocument = WordprocessingDocument.Open(ReportFile, true)
Body body = new Body();
Paragraph paragraph = new Paragraph();
SectionProperties sectionProp = new SectionProperties(new PageSize() { Width = (UInt32Value)15840U, Height = (UInt32Value)12240U, Orient = PageOrientationValues.Landscape });
body.Append(paragraph);
body.Append(sectionProp);
WordDocument.MainDocumentPart.Document.Append(body);
那么，有没有办法改变单个段落/页面的方向呢?
你必须放一个下一页分隔符开始一个新的部分，并设置该部分的方向。一旦你完成了，用默认的页面方向开始一个新的部分。
下一页开始横向分割:
doc.MainDocumentPart.Document.Body.Append(
new Paragraph(
new ParagraphProperties(
new SectionProperties(
new PageSize() { Width = (UInt32Value)12240U, Height = (UInt32Value)15840U, Orient = PageOrientationValues.Landscape },
new PageMargin() { Top = 720, Right = Convert.ToUInt32(rightmargin * 1440.0), Bottom = 360, Left = Convert.ToUInt32(leftmargin * 1440.0), Header = (UInt32Value)450U, Footer = (UInt32Value)720U, Gutter = (UInt32Value)0U }))));
下一页分隔符开始纵向:
doc.MainDocumentPart.Document.Body.Append(
new Paragraph(
new ParagraphProperties(
new SectionProperties(
new PageSize() { Width = (UInt32Value)12240U, Height = (UInt32Value)15840U },
new PageMargin() { Top = 720, Right = Convert.ToUInt32(rightmargin * 1440.0), Bottom = 360, Left = Convert.ToUInt32(leftmargin * 1440.0), Header = (UInt32Value)450U, Footer = (UInt32Value)720U, Gutter = (UInt32Value)0U }))));
根据上面的对话和我的理解，代码可能如下所示:
在Main方法中调用子方法:
using (WordprocessingDocument package = WordprocessingDocument.Create(filePath, WordprocessingDocumentType.Document))
{
package.AddMainDocumentPart();
package.MainDocumentPart.Document = new Document();
Body body = package.MainDocumentPart.Document.Body = new Body();
Paragraph para1 = CreatePara1(); // Paragraph 1 Portrait
Paragraph breakBefore = CreateBreakBefore(); // Break before next paragraph that would be landscape
Paragraph para2 = CreatePara2(); // Paragraph 2 Landscape
Paragraph breakAfter = CreateBreakAfter(); // Break after previous paragraph that was landscape
Paragraph para3 = CreatePara3(); // Paragraph 3 Portrait again
body.Append(para1);
body.Append(breakBefore);
body.Append(para2);
body.Append(breakAfter);
body.Append(para3);
}
在子方法之后:
private static Paragraph CreatePara1()
{
Paragraph para1 = new Paragraph();
Run run1 = new Run(new Text("This is Paragraph one."));
para1.Append(run1);
return para1;
}
private static Paragraph CreateBreakBefore()
{
Paragraph paragraph2 = new Paragraph() { RsidParagraphAddition = "00BA2F0F", RsidParagraphProperties = "00BA2F0F", RsidRunAdditionDefault = "00BA2F0F" };
ParagraphProperties paragraphProperties1 = new ParagraphProperties();
SectionProperties sectionProperties1 = new SectionProperties() { RsidR = "00BA2F0F" };
PageSize pageSize1 = new PageSize() { Width = (UInt32Value)12240U, Height = (UInt32Value)15840U };
PageMargin pageMargin1 = new PageMargin() { Top = 1440, Right = (UInt32Value)1440U, Bottom = 1440, Left = (UInt32Value)1440U, Header = (UInt32Value)720U, Footer = (UInt32Value)720U, Gutter = (UInt32Value)0U };
Columns columns1 = new Columns() { Space = "720" };
DocGrid docGrid1 = new DocGrid() { LinePitch = 360 };
sectionProperties1.Append(pageSize1);
sectionProperties1.Append(pageMargin1);
sectionProperties1.Append(columns1);
sectionProperties1.Append(docGrid1);
paragraphProperties1.Append(sectionProperties1);
paragraph2.Append(paragraphProperties1);
return paragraph2;
}
private static Paragraph CreatePara2()
{
Paragraph para2 = new Paragraph() { RsidParagraphAddition = "00BA2F0F", RsidParagraphProperties = "00BA2F0F", RsidRunAdditionDefault = "00BA2F0F" };
BookmarkStart bookmarkStart1 = new BookmarkStart() { Name = "_GoBack", Id = "0" };
Run run2 = new Run();
LastRenderedPageBreak lastRenderedPageBreak1 = new LastRenderedPageBreak();
Text text2 = new Text();
text2.Text = "This is the paragraph two";
run2.Append(lastRenderedPageBreak1);
run2.Append(text2);
para2.Append(bookmarkStart1);
para2.Append(run2);
BookmarkEnd bookmarkEnd1 = new BookmarkEnd() { Id = "0" };
return para2;
}
private static Paragraph CreateBreakAfter()
{
Paragraph paragraph4 = new Paragraph() { RsidParagraphAddition = "00BA2F0F", RsidParagraphProperties = "00BA2F0F", RsidRunAdditionDefault = "00BA2F0F" };
ParagraphProperties paragraphProperties2 = new ParagraphProperties();
SectionProperties sectionProperties2 = new SectionProperties() { RsidR = "00BA2F0F", RsidSect = "00BA2F0F" };
PageSize pageSize2 = new PageSize() { Width = (UInt32Value)15840U, Height = (UInt32Value)12240U, Orient = PageOrientationValues.Landscape };
PageMargin pageMargin2 = new PageMargin() { Top = 1440, Right = (UInt32Value)1440U, Bottom = 1440, Left = (UInt32Value)1440U, Header = (UInt32Value)720U, Footer = (UInt32Value)720U, Gutter = (UInt32Value)0U };
Columns columns2 = new Columns() { Space = "720" };
DocGrid docGrid2 = new DocGrid() { LinePitch = 360 };
sectionProperties2.Append(pageSize2);
sectionProperties2.Append(pageMargin2);
sectionProperties2.Append(columns2);
sectionProperties2.Append(docGrid2);
paragraphProperties2.Append(sectionProperties2);
paragraph4.Append(paragraphProperties2);
return paragraph4;
}
private static Paragraph CreatePara3()
{
Paragraph para3 = new Paragraph();
Run run3 = new Run(new Text("This is Paragraph three."));
para3.Append(run3);
return para3;
