C#中操作Word（4）—— 利用Range对象设置文本的格式

        本文主要介绍修改文本的格式的方法。按照上文介绍的方法，现在将D盘的Test.docx文档进行修改，修改成如下内容：



        在“测试”按钮的单击事件处理函数中，获取对应的Range：

private void button1_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
string version = app.Version;
Console.WriteLine(version);
Document doc = app.Documents.Open("D:\\Test.docx");
doc.ActiveWindow.Visible = true;
Range range = doc.Range();
range.Select();
doc.Save();
//app.Quit();
app = null;
}

        下面我们通过range来控制word中文本的格式：

1、修改字体

        设置字体的格式为微软雅黑，字体的大小为14：

range.Font.Size = 14;
range.Font.Name = "微软雅黑";

2、修改对齐方式

        修改成居中对齐：

range.ParagraphFormat.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;

3、加粗

range.Bold = 10;

4、增加下划线

range.Underline = Microsoft.Office.Interop.Word.WdUnderline.wdUnderlineDotDash;

5、选中文本

range.Select();

        最终的代码如下：

private void button1_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
string version = app.Version;
Console.WriteLine(version);
Document doc = app.Documents.Open("D:\\Test.docx");
doc.ActiveWindow.Visible = true;
Range range = doc.Range();
range.Font.Size = 14;
range.Font.Name = "微软雅黑";
range.ParagraphFormat.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;
range.Bold = 10;
range.Underline = Microsoft.Office.Interop.Word.WdUnderline.wdUnderlineDotDash;
range.Select();
doc.Save();
//app.Quit();
app = null;
}

6、设置对齐方式                  

range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;
range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphRight;
range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphLeft;
