【求大家帮忙看看代码】C#读取PPT
我想实现查找PPT内容的程序
我的程序如下:
protected void Button3_Click(object sender, EventArgs e)
{
bool b = false;
string file = @ "E:\Net实训\Lesson9.ppt "; //搜索文件
Microsoft.Office.Interop.PowerPoint.Application pptApp = new Microsoft.Office.Interop.PowerPoint.ApplicationClass();
Microsoft.Office.Interop.PowerPoint.Presentation pptPre = pptApp.Presentations.Open(file,
Microsoft.Office.Core.MsoTriState.msoTrue,
Microsoft.Office.Core.MsoTriState.msoFalse,
Microsoft.Office.Core.MsoTriState.msoFalse);
Microsoft.Office.Interop.PowerPoint.Slides mySlides = pptPre.Slides;
string strSearch = "多线程 "; //搜索内容
Microsoft.Office.Interop.PowerPoint.TextRange oText = null;
foreach (Microsoft.Office.Interop.PowerPoint.Slide slide in pptPre.Slides)
{
foreach (Microsoft.Office.Interop.PowerPoint.Shape shape in slide.Shapes)
{
oText = shape.TextFrame.TextRange.Find(strSearch, 0,
Microsoft.Office.Core.MsoTriState.msoFalse,
Microsoft.Office.Core.MsoTriState.msoTrue);
if (oText != null)
{
b = true;
break;
}
else
b = false;
}
}
if (b)
Response.Write( "Find ");
}
-------------------------
错误:TextFrame (unknown member) : Invalid request. This type of shape cannot have a TextRange
