Reusing Style Objects

Reusing style objects can save memory and make a program faster.

To apply some formatting to a large range of cells in a worksheet:

1. Create a style object.
2. Specify the attributes.
3. Apply the style to the cells in the range.

// 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();

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

// Access cells
Cell cell1 = worksheet.Cells["A1"];
Cell cell2 = worksheet.Cells["B1"];

// Set the styles of both cells to Times New Roman
Style styleObject = workbook.CreateStyle();
styleObject.Font.Color = System.Drawing.Color.Red;
styleObject.Font.Name = "Times New Roman";
cell1.SetStyle(styleObject);
cell2.SetStyle(styleObject);

// Put the values inside the cell
cell1.PutValue("Hello World!");
cell2.PutValue("Hello World!!");

// Save to Pdf without setting PdfSaveOptions.IsFontSubstitutionCharGranularity
workbook.Save(dataDir + "SampleOutput_out.xlsx");

Because the Cell.GetStyle/Cell.SetStyle approach uses a lot less memory, and is efficient, the older Cell.Style property which consumed a lot of unnecessary memory, was removed with the release of Aspose.Cells 7.1.0.
