Export Image to Excel using c#

Here am trying to show how we can export an image to excel file.

References Used: Microsoft.Office.Interop.Excel;

Link for downloading the dlls and install : Office XP PIAs

Add Microsoft.Office.Interop.Excel.dll to the bin folder.

Add office.dll to the bin folder.

String sFileImage = System.IO.Path.Combine(System.Configuration.ConfigurationManager.AppSettings["UploadPath"], Session["UserId"].ToString() + ".gif");
String sFilePath = System.IO.Path.Combine(System.Configuration.ConfigurationManager.AppSettings["UploadPath"], Session["UserId"].ToString() + ".xls");
if (File.Exists(sFilePath)) { File.Delete(sFilePath); }

Microsoft.Office.Interop.Excel.ApplicationClass objApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
Microsoft.Office.Interop.Excel.Worksheet objSheet = new Microsoft.Office.Interop.Excel.Worksheet();
Microsoft.Office.Interop.Excel.Workbook objWorkBook = null;
//object missing = System.Reflection.Missing.Value;

try
{
objWorkBook = objApp.Workbooks.Add(Type.Missing);
objSheet = (Microsoft.Office.Interop.Excel.Worksheet)objWorkBook.ActiveSheet;

//Add picture to single sheet1
objSheet = (Worksheet)objWorkBook.Sheets[1];
objSheet.Name = "Graph with Report";

//////////////

Or multiple sheets

for (int iSheet = 0; iSheet < objWorkBook.Sheets.Count - 1; iSheet++)
{
objSheet = objWorkBook.Sheets[iSheet] as Worksheet;
///(objSheet as Microsoft.Office.Interop.Excel._Worksheet).Activate();
}

/////////////////

objSheet.Shapes.AddPicture(sFileImage, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue, 10, 10, 700, 350);
objWorkBook.SaveAs(sFilePath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}
