从 Excel 文件中提取主题数据

Aspose.Cells 允许用户从 Excel 文件中提取主题相关数据。例如，您可以提取应用于工作簿的主题名称和应用于单元格或单元格边框的主题颜色等。

您可以使用 Microsoft Excel 通过页面布局 > 主题命令将主题应用到您的工作簿。

C# 从 Excel 文件中提取主题数据的代码

以下示例代码提取应用于源工作簿的主题名称，然后提取应用于单元格 A1 的主题颜色和应用于单元格底部边框的主题颜色。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Create workbook object
Workbook workbook = new Workbook(dataDir + "source.xlsx");

// Extract theme name applied to this workbook
Console.WriteLine(workbook.Theme);

// Access first worksheet
Worksheet worksheet = workbook.Worksheets[0];

// Access cell A1
Cell cell = worksheet.Cells["A1"];

// Get the style object
Style style = cell.GetStyle();

if (style.ForegroundThemeColor != null)
{
    // Extract theme color applied to this cell if theme has foregroundtheme color defined
    Console.WriteLine(style.ForegroundThemeColor.ColorType);
}
else
{
    Console.WriteLine("Theme has not foreground color defined.");
}

// Extract theme color applied to the bottom border of the cell if theme has border color defined
Border bot = style.Borders[BorderType.BottomBorder];
if (bot.ThemeColor != null)
{
    Console.WriteLine(bot.ThemeColor.ColorType);
}
else
{
    Console.WriteLine("Theme has not Border color defined.");
}
