C# Excel 中设置文字对齐方式、方向和换行

在Excel表格中输入文字时，我们常常需要调整文字对齐方式或者对文字进行换行。本文将介绍如何通过编程的方式设置文字对齐方式，改变文字方向以及对文字进行换行。

//创建Workbook对象
Workbook wookbook = new Workbook();
Worksheet sheet = wookbook.Worksheets[0];

//添加说明文字
sheet.Range["B1"].Text = "文字对齐方式";
sheet.Range["D1"].Text = "文字方向";
sheet.Range["F1"].Text = "文字换行";
sheet.Range["B1:F1"].Style.Font.IsBold = true;

//左对齐
sheet.Range["B3"].Text = "左对齐";
sheet.Range["B3"].Style.HorizontalAlignment = HorizontalAlignType.Left;

//水平居中
sheet.Range["B4"].Text = "水平居中";
sheet.Range["B4"].Style.HorizontalAlignment = HorizontalAlignType.Center;

//右对齐
sheet.Range["B5"].Text = "右对齐";
sheet.Range["B5"].Style.HorizontalAlignment = HorizontalAlignType.Right;

//居上
sheet.Range["B7"].Text = "居上";
sheet.Range["B7"].Style.VerticalAlignment = VerticalAlignType.Top;

//居中
sheet.Range["B8"].Text = "垂直居中";
sheet.Range["B8"].Style.VerticalAlignment = VerticalAlignType.Center;

//居下
sheet.Range["B9"].Text = "居下";
sheet.Range["B9"].Style.VerticalAlignment = VerticalAlignType.Bottom;

//分散对齐并居中
sheet.Range["B10"].Text = "水平分散对齐+垂直居中";
sheet.Range["B10"].Style.HorizontalAlignment = HorizontalAlignType.Distributed;
sheet.Range["B10"].Style.VerticalAlignment = VerticalAlignType.Center;

//逆时针旋转45°
sheet.Range["D7"].Text = "旋转45°";
sheet.Range["D7"].Style.Rotation = 45;

//逆时针旋转90°
sheet.Range["D8"].Text = "旋转90°";
sheet.Range["D8"].Style.Rotation = 90;

//顺时针旋转45°
sheet.Range["D9"].Text = "旋转-45°";
sheet.Range["D9"].Style.Rotation = 135;

//顺时针旋转90°
sheet.Range["D10"].Text = "旋转-90°";
sheet.Range["D10"].Style.Rotation = 180;

//添加‘\n’进行文字换行
sheet.Range["F9"].Text = "这是\n手动\n换行";

//自动换行
sheet.Range["F10"].Text = "这是自动换行（额外测试文字）";
sheet.Range["F10"].Style.WrapText = true;

//设置列宽、行高
sheet.Columns[1].ColumnWidth = 15;
sheet.Columns[3].ColumnWidth = 15;
sheet.Columns[5].ColumnWidth = 15;
sheet.Range["B3:B5"].RowHeight = 15;
sheet.Range["B7:B10"].RowHeight = 50;

//保存文档
wookbook.SaveToFile("TextAlignment.xlsx", FileFormat.Version2013);
