我是使用Microsoft.Office.Interop.Word. 考虑到我有一个标题为“Header1”样式的 word 文档,并且它下面包含一些“normal”样式的句子。现在我需要找到属于“Header 1”样式段落的那些行。这是我被编码的原因:
foreach (Microsoft.Office.Interop.Word.Paragraph paragraph in doc.Paragraphs)
{
Microsoft.Office.Interop.Word.Style style = paragraph.get_Style() as Microsoft.Office.Interop.Word.Style;
string styleName = style.NameLocal;
string text = paragraph.Range.Text;

这里,method2在调用时运行,但在执行其委托方法之前,method3开始执行.怎么避免呢?请提出任何建议或代码
我在方法2中调用了与其委托的nsurl连接
