ppt中的中英文字体设置不一致？

C#代码要先添加两个引用。COM的microsoft office XX Object Library和microsoft office interop powerpoint

 

Microsoft.Office.Interop.PowerPoint.Application pptApplication = null;

Microsoft.Office.Interop.PowerPoint.Presentation pptPresentation = null;

 //start power point
 pptApplication = new Microsoft.Office.Interop.PowerPoint.Application();
//open powerpoint document
 pptPresentation = pptApplication.Presentations.Open(originalPptPath,Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse);

foreach (Microsoft.Office.Interop.PowerPoint.Slide slide in pptPresentation.Slides)
                {//开始读取每一个数据块
                    foreach (Microsoft.Office.Interop.PowerPoint.Shape item in slide.Shapes)
                    {
                        if (item.HasTextFrame == Microsoft.Office.Core.MsoTriState.msoTrue)//判断内容是否为文字
                        {
                            item.TextFrame.TextRange.Font.Name = "Clear Sans";//设置西洋字符格式
                            item.TextFrame.TextRange.Font.NameFarEast = "Noto Sans S Chinese Bold";//设置亚洲字符格式
                        }
                    }
                }
