在VSTO和Aspose.Cells中插入和移除工作表中的单元格注释

要向单元格添加注释：

1. 打开一个现有的Excel文件。
2. 向单元格添加评论。
3. 保存文件。

要删除注释，该过程类似，唯一不同之处在于注释被移除。

下面的代码示例首先说明了如何添加评论，然后说明了如何使用VSTO或Aspose.Cells for .NET移除评论。

插入注释

这些代码片段展示了如何首先使用VSTO（C＃）向单元格添加评论，然后再使用Aspose.Cells for .NET（C#）。

VSTO

 //Instantiate the Application object.

 Excel.Application excelApp = Application;

//Specify the template excel file path.

  string myPath = "Book1.xls";

//Open the excel file.

 excelApp.Workbooks.Open(myPath, Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value);

//Get the A1 cell.

 Excel.Range rng1 = excelApp.get_Range("A1", Missing.Value);

//Add the comment with text.

 rng1.AddComment("This is my comment");

//Save the file.

  excelApp.ActiveWorkbook.Save();

//Quit the Application.

  excelApp.Quit();

Aspose.Cells

 //Specify the template excel file path.

string myPath = "Book1.xls";

//Instantiate a new Workbook.

//Open the excel file.

 Workbook workbook = new Workbook(myPath);

//Add a Comment to A1 cell.

 int commentIndex = workbook.Worksheets[0].Comments.Add("A1");

//Accessing the newly added comment

 Comment comment = workbook.Worksheets[0].Comments[commentIndex];

//Setting the comment note

 comment.Note = "This is my comment";

//Save As the excel file.

 workbook.Save("Book1.xls");

移除评论

要从单元格移除评论，请使用VSTO（C＃）和Aspose.Cells for .NET（C#）的以下代码行。

VSTO

 //Remove the comment.

  rng1.Comment.Delete();

Aspose.Cells

 //removing comments

 workbook.Worksheets[0].Comments.RemoveAt("A1");
