發行說明

• 新增使用密碼加密和解密".xlsx"、".xlsm"和".xltx"檔案的功能。 Use WorkBook.SaveAs(string fileName, string password) method to encrypt the WorkBook with provided password when saving it. Use WorkBook.Load(string filename, string password) method to decrypt file with provided password when loading the workbook. 密碼也可以透過以下方式指定：
  • Using WorkBook.Password property (workbook will be encrypted on save if this property is not null, and will not be encrypted if it is null)
  • Using SavingOptions object with SavingOptions.Password property, when calling WorkBook.SaveAs(string fileName, SavingOptions options) method
  • Using LoadingOptions object with LoadingOptions.Password property, when calling WorkBook.Load(string filename, LoadingOptions options) method
• To check if the WorkBook object will be encrypted on save use WorkBook.IsEncrypted boolean property. Encryption can also be turned off by assigning WorkBook.IsEncrypted = false (Note: workbook cannot be encrypted by assigning WorkBook.IsEncrypted = true, this will throw an exception at runtime, asking to instead specify a password).
• 如果將密碼設定為".xlsx"、".xlsm"和".xltx"以外的工作簿類型，也會在執行時拋出異常，提醒使用者無法加密該工作簿。
• 新增對 .NET 6.0 的支援
• Removes dependency on System.Common.Drawing
• 移除對 .NET Framework 4.5 的支援。現在支援的最低 .NET Framework 版本為 4.6.2。
• Breaking change: WorkBook.SaveAs(string filename, string listDelimiter) method was renamed to WorkBook.SaveAsWithCustomDelimiter(string filename, string listDelimiter) to remove ambiguity between SaveAs(string filename, string listDelimiter) and SaveAs(string fileName, string password) methods.
• Breaking change: IronXL.Drawing.Images.IImage.ToBitmap() method is removed, as System.Common.Drawing is no longer supported.
• Breaking change: IronXL.Drawing.Images.IImage.ToImage() method now returns a SixLabors.ImageSharp.Image object used as a replacement for removed System.Common.Drawing objects.
• 修正了 XLSX 工作簿中儲存格或區域的背景顏色在 Excel 中無法呈現的錯誤。
• 修正了泰語區域設定拋出許可證異常的錯誤
• Fixes a bug where each time a new cell was assigned a DateTime value in XLSX workbook a new cell style was created for each cell, overflowing the style table and breaking the resulting file if the number of cells was > 64000.
• Improves speed of creating large amounts of cells with a DateTime value and format. For example, creating a workbook with 80K DateTime value and format cells on a single worksheet used to take 25 seconds, and now takes less than 0.8 seconds (actual performance will depend on the environment the code is executed in).

發行說明

• Adds a way to change the string value of a cell without automatically formatting the cell: this is achieved through StringValue property of a Cell.
• Adds AutoSizeRow method to Row and WorkSheet, which changes the height of a row to fit the contents.
• Adds AutoSizeColumn method to Column and WorkSheet, which changes the width of a row to fit the contents.
• 修正了新增或變更邊框時拋出異常的錯誤。
• 修正了一個錯誤，當儲存格值變更為依賴單一儲存格的公式時（例如"=A1"），會拋出例外。
• 修正了一個錯誤，即當將類似"12-720"的字串新增至儲存格時，該字串會被解析為 720 年的日期。 Excel 不支援 1900 年之前的日期。像這樣的字串不再被解析為日期。 但是，1900 年之後可以解析為有效日期的字串仍將被解析為日期。 例如"12-1956"。 Use StringValue property to bypass this parse.
• 修正了一個錯誤，即載入、變更和儲存現有工作簿時，儲存格的內容變更後可能會遺失原始格式。 情況已不再如此。

發行說明

• Adds a new IronXL.Formatting.ConditionType.
• Old IronXL.Formatting.Enums.ConditionType is obsolete.

• 修正了載入包含 .bmp 映像的文件，但無法透過程式碼存取 .bmp 映像的錯誤。
• 修正了建立包含任何大量已使用儲存格的工作簿時，儲存後產生的檔案會損壞的錯誤。
• 修復了一些其他罕見的錯誤，這些錯誤偶爾可能會導致檔案損壞。
• 修正了對一系列儲存格套用樣式變更時耗時過長的問題。樣式變更包括字型變更（高度、粗體等）、垂直對齊方式、水平對齊方式等。
• 提高了產生檔案的整體穩定性，包括使用 IronXL 建立的檔案以及由 IronXL 匯入和編輯的檔案。
• 大大提高了效能，以前生成一個包含 10000 個已使用單元格的檔案需要 1.5 分鐘，現在只需 20 秒（具體時間取決於您的程式碼對單元格執行的操作）。
