Add image to Excel header in C#, VB.NET
Syncfusion Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. Using this library, you can add image to Excel header in C# and VB.NET.
Header and footer are used to add additional information to worksheet for printing Excel documents. You can add image to Excel header by using the IPageSetup.RightHeaderImage property. And, you should use script command "&G" which is used to represent the picture in the IPageSetup.RightHeader property.
Steps to add image to Excel header programmatically:
Step 1: Create a new C# console application project.
Create a new C# console application
Step 2: Install Syncfusion.XlsIO.WinForms NuGet package as a reference to your .NET Framework applications from the NuGet.org.
Install NuGet package
Step 3: Include the following namespace in the Program.cs file.
C#
using Syncfusion.XlsIO;
VB.NET
Imports Syncfusion.XlsIO
Step 4: Use the following code snippet to create Excel file with simple text.
C#
//Create an instance of ExcelEngine
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Set the default application version as Excel 2016
excelEngine.Excel.DefaultVersion = ExcelVersion.Excel2016;
//Create a workbook with a worksheet
IWorkbook workbook = excelEngine.Excel.Workbooks.Create(1);
//Access first worksheet from the workbook instance
IWorksheet worksheet = workbook.Worksheets[0];
//Insert sample text into cell “E15”
worksheet.Range["E15"].Text = "Hello World";
IPageSetup pageSetup = ( IPageSetup )worksheet.PageSetup;
//Add Right Header Image
pageSetup.RightHeaderImage = Image.FromFile(@"syncfusion_logo.gif");
pageSetup.RightHeader = "&G";
//Save the workbook to disk in xlsx format
workbook.SaveAs("Output.xlsx");
}
VB.NET
