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
