文本居中怎么設置？

oPara1.Range.Text="我需要居中"; //插入文本

oPara1.Range.ParagraphFormat.Alignment =Word.WdParagraphAlignment.wdAlignParagraphCenter; //我的意圖是讓這段文字居中，但這樣做是不行的

把這兩句調換順序試試……

如果不行的話，我的寫法是這樣的：

Object Nothing = System.Reflection.Missing.Value;

worddoc.Paragraphs.Last.Alignment = WdParagraphAlignment.wdAlignParagraphCenter;

worddoc.Paragraphs.Last.Range.Text = "我需要居中";

worddoc.Paragraphs.Add(ref Nothing);

worddoc.Paragraphs.Last.Alignment = WdParagraphAlignment.wdAlignParagraphRight;

worddoc.Paragraphs.Last.Range.Text = "我需要右對齊";
