如何使用.net将powerpoint转为html文件
我们当然要使用com组件了，所以要先安装powerpoint2000,在vs.net里面添加一个refrence,找到microsoft powerpoint object library 9.0，添加进来。
然后写如下代码，很简单，我就不必解释了：）
using system;
using office;
using powerpoint;
namespace courseserver.course
{

set

_htmlfilename=value;
}

public void convert(string pptfilename)
{
pptfile=ppt.presentations.open(pptfilename,office.msotristate.msotrue,office.msotristate.msoctrue,office.msotristate.msofalse);
pptfile.saveas(_htmlfilename,powerpoint.ppsaveasfiletype.ppsaveashtml,office.msotristate.msoctrue);
pptfile.close();
}
}
}
