C# Excel批注“哪种开发语言最好”

骑猪看日落 2023-10-16 21:55 12阅读 0赞

Excel批注常用于为个别的单元格添加注释，读者能够从注释中获取额外的信息。批注可隐藏，只会在单元格右上方显示红色三角，添加后不会对单元格的内容喧宾夺主。在日常编程处理Excel中，为个别单元格添加备注信息，也有必要。这篇博文主要介绍使用免费版的Spire.XLS在C\#中为单元格添加备注，并设置位置，大小，富文本及文本对齐方式。

想尝试的朋友可以从以下三个地址下载Free Spire.XLS: [E-iceblue官网下载][E-iceblue]；[Nuget][]；[CSDN下载][CSDN]。下载之后，请将bin 文件夹里的.dll添加为VS的引用。

**步骤一:** 创建一个新的工作薄和表单。

Workbook workbook = new Workbook();
                Worksheet sheet = workbook.Worksheets[0];

**步骤二：**启用类ExcelFont添加设置字体，在设置comment文本时会用到。

ExcelFont font1 = workbook.CreateFont();
                font1.FontName = "仿宋";
                font1.Color = Color.Red;
                font1.IsBold = true;
                font1.Size = 12;
                ExcelFont font2 = workbook.CreateFont();
                font2.FontName = "仿宋";
                font2.Color = Color.Blue;
                font2.Size = 12;
                font2.IsBold = true;
                ExcelFont font3 = workbook.CreateFont();
                font3.FontName = "Calibri";
                font3.Color = Color.Blue;
                font3.Size = 12;
                font3.IsBold = true;

**步骤三：**为单元格F5添加批注1，设置其大小，位置，文本，文本对齐方式。

ExcelComment Comment1 = sheet.Range["F5"].Comment;
                Comment1.IsVisible = true;
                //设置批注高度和宽度
                Comment1.Height = 150;
                Comment1.Width = 300;
                //设置批注位置
                Comment1.Top = 20;
                Comment1.Left = 40;
                //设置文本内容，对齐方式，文本旋转
                Comment1.RichText.Text = "为了防止人类齐心协力开发出人工智能，上帝给了程序员不同的开发语言。但哪种语言才是最好的呢？";
                Comment1.RichText.SetFont(0, 32, font2);
                Comment1.RichText.SetFont(33, 44, font1);
                Comment1.TextRotation = TextRotationType.LeftToRight;
                Comment1.VAlignment = CommentVAlignType.Center;
                Comment1.HAlignment = CommentHAlignType.Justified;

**步骤四：**添加批注2作为对照。

ExcelComment Comment2= sheet.Range["F14"].Comment;
                Comment2.IsVisible = true;
                Comment2.Height = 150;
                Comment2.Width = 300;
                Comment2.RichText.Text = "About E-iceblue: \nE-iceblue focuses on providing excellent office components for developers to operate Word, Excel, PDF, and PowerPoint documents.";
                Comment2.TextRotation = TextRotationType.LeftToRight;
                Comment2.RichText.SetFont(0, 16, font2);
                Comment2.Top = 170;
                Comment2.Left = 450;
                Comment2.VAlignment = CommentVAlignType.Top;
                Comment2.HAlignment = CommentHAlignType.Justified;

**步骤五：**保存文档，并启动查看效果。

workbook.SaveToFile("S3.xlsx", ExcelVersion.Version2010);
                System.Diagnostics.Process.Start("S3.xlsx");
