本文将介绍如何使用spire.presentation for .net在powerpoint文档中使用正则表达式替换文本。

using spire.presentation;
using system.text.regularexpressions;
namespace replacetextwithregex
{
    class program
    {
        static void main(string[] args)
        {
            //创建presentation实例
            presentation ppt = new presentation();
            //加载示例文档
            ppt.loadfromfile("sample.pptx");
            //获取第一张幻灯片
            islide slide = ppt.slides[0];
            //替换该幻灯片中所有“abc”以及其后到行尾的内容为“abc def”
            regex regex = new regex("abc.*");
            string newvalue = "abc def";
            foreach (ishape shape in slide.shapes)
            {
                shape.replacetextwithregex(regex, newvalue);
            }
            //保存结果文档
            ppt.savetofile("replacetextwithregex.pptx", fileformat.pptx2013);
        }
    }
}

imports spire.presentation
imports system.text.regularexpressions
namespace replacetextwithregex
    friend class program
        private shared sub main(byval args as string())
            '创建presentation实例
            dim ppt as presentation = new presentation()
            '加载示例文档
            ppt.loadfromfile("sample.pptx")
            '获取第一张幻灯片
            dim slide as islide = ppt.slides(0)
            '替换该幻灯片中所有“abc”以及其后到行尾的内容为“abc def”
            dim regex as regex = new regex("abc.*")
            dim newvalue as string = "abc def"
            for each shape as ishape in slide.shapes
                shape.replacetextwithregex(regex, newvalue)
            next
            '保存结果文档
            ppt.savetofile("replacetextwithregex.pptx", fileformat.pptx2013)
        end sub
    end class
end namespace
