导出带图片的Excel报表
最近工作需要用到导出报表中带用图片，在网上一番苦找和自己实验，终于导出了图片，下面分享方法，希望有用
先引用 Microsoft.Office.Tools.Excel.v4.0.Utilities.dll程序集，然后在后台页面引用using Excel = Microsoft.Office.Interop.Excel;
然后后台写下面这段：
#region 导出Excel
Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
protected void BtnExport_Click(object sender, EventArgs e)
{
string SN = this.txt_SN.Text;
DataTable dt= CpacSNBLL.GetCpacSNBLL(SN);
ImportDataToExcel(dt);
}
#region 导出
private void ImportDataToExcel(DataTable dt)
{
if (dt != null)
{
#region 操作excel
xlWorkBook = new Microsoft.Office.Interop.Excel.Application().Workbooks.Add(Type.Missing);
xlWorkBook.Application.Visible = false;

//设置标题

xlWorkSheet.Cells[1, 12] = "Amend_Dte";
//设置宽度，默认宽度和高度会改变图片的尺寸
