The following code example illustrates how to get the RGB color value for the applied cell color in an Excel document.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Xlsx;
//Create a workbook
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Apply cell background color
worksheet.Range["A1"].CellStyle.ColorIndex = ExcelKnownColors.Custom50;
//Get the RGB values of the cell color
Color color = worksheet.Range["A1"].CellStyle.Color;
byte red = color.R;
byte green = color.G;
byte blue = color.B;
Console.WriteLine($"Red: {red}, Green: {green}, Blue: {blue}");
}
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Xlsx;
//Create a workbook
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Apply cell background color
worksheet.Range["A1"].CellStyle.ColorIndex = ExcelKnownColors.Custom50;
//Get the RGB values of the cell color
Color color = worksheet.Range["A1"].CellStyle.Color;
byte red = color.R;
byte green = color.G;
byte blue = color.B;
Console.WriteLine($"Red: {red}, Green: {green}, Blue: {blue}");
}
Using excelEngine As New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Xlsx
'Create a workbook
Dim workbook As IWorkbook = application.Workbooks.Create(1)
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Apply cell background color
worksheet.Range("A1").CellStyle.ColorIndex = ExcelKnownColors.Custom50
'Get the RGB values of the cell color
Dim color As Color = worksheet.Range("A1").CellStyle.Color
Dim red As Byte = color.R
Dim green As Byte = color.G
Dim blue As Byte = color.B
Console.WriteLine($"Red: {red}, Green: {green}, Blue: {blue}")
