c#/vb.net 添加或删除 powerpoint 段落和设置段落样式-凯发线上登陆下载网址

在使用c#创建powerpoint文档的过程中，我们首先需要添加一个shape图形到幻灯片文档,然后在图形中添加多个段落并设置段落格式。该示例将详细描述如何使用spire.presentation 添加或删除powerpoint段落。

添加段落到幻灯片

//新建一个powerpoint文档并获取第一个幻灯片
presentation presentation = new presentation();
 islide slide = presentation.slides[0];
//添加一个shape到第一张幻灯片并设置其大小，颜色
 iautoshape shape = slide.shapes.appendshape(shapetype.rectangle, new rectanglef(50, 70, 600, 200));
 shape.fill.filltype = fillformattype.none;
 shape.shapestyle.linecolor.color = color.white;
 
//在图形上添加第一个段落及文字    
 shape.textframe.paragraphs[0].textranges.append(new textrange("使用代码添加段落到幻灯片"));
 //在图形上添加第二个段落及文字   
 string text = "一款专业的 powerpoint 组件，使用该组件，开发者可以在 .net 平台上对 powerpoint 文档进行生成、读取、写入、修改、转换和打印等操作。";
 textparagraph p=new textparagraph();
 p.text=text;
 shape.textframe.paragraphs.append(p);
 
//设置段落中文字的字体与颜色   
 foreach (textparagraph para in shape.textframe.paragraphs)
 {
     foreach (textrange range in para.textranges)
     {
         range.latinfont = new textfont("宋体");
         range.fill.filltype = fillformattype.solid;
         range.fill.solidcolor.color = color.black;
     }
//设置段落对齐方式、段首缩进及行距
   para.alignment = textalignmenttype.left;
   para.indent = 50;
   para.linespacing = 150;
 }
//保存文档
 presentation.savetofile("result.pptx", fileformat.pptx2010);

dim p as new textparagraph()
p.text = text
shape.textframe.paragraphs.append(p)
'设置段落中文字的字体与颜色   
for each para as textparagraph in shape.textframe.paragraphs
	for each range as textrange in para.textranges
		range.latinfont = new textfont("宋体")
		range.fill.filltype = fillformattype.solid
		range.fill.solidcolor.color = color.black
	next
	'设置段落对齐方式、段首缩进及行距
	para.alignment = textalignmenttype.left
	para.indent = 50
	para.linespacing = 150
next
'保存文档
presentation.savetofile("result.pptx", fileformat.pptx2010)

删除段落

//加载文档
presentation presentation = new presentation();
presentation.loadfromfile("result.pptx",fileformat.pptx2010);
//获取第一张幻灯片
islide slide = presentation.slides[0];
//获取第一个图形
iautoshape shape = slide.shapes[0] as iautoshape;
//删除图形里的第二个段落
shape.textframe.paragraphs.removeat(1);
//保存文档
presentation.savetofile("removepara.pptx", fileformat.pptx2010);

'加载文档
dim presentation as new presentation()
presentation.loadfromfile("result.pptx", fileformat.pptx2010)
'获取第一张幻灯片
dim slide as islide = presentation.slides(0)
'获取第一个图形
dim shape as iautoshape = trycast(slide.shapes(0), iautoshape)
'删除图形里的第二个段落
shape.textframe.paragraphs.removeat(1)
'保存文档
presentation.savetofile("removepara.pptx", fileformat.pptx2010)
