最近在項目中第一次接觸到excel部分的東西，是以學習了解了一下EppPlus，首先，引入兩篇我覺得寫的不錯的博文：
介紹詳細用法：

一個方法，看起來比較受啟發，web方面的儲存等：

之後，官網的網址及官網的WebapplicationExample
http://epplus.codeplex.com/wikipage?title=WebapplicationExample
最後貼出我自己的方法：
public static void ExportExcelFillWithDataByWeb(string filePath,string fileName, string sheetName, IDictionary<string, string> data)
{
try
{
FileInfo file = new FileInfo(filePath);
if (file.Exists)
{
using (var ExcelPlus = new ExcelPackage(file))
{
var sheet = ExcelPlus.Workbook.Worksheets[sheetName];
if (sheet!=null)
{
foreach (var kv in data)
{
sheet.Cells[kv.Key].Value = kv.Value;
}
var httpContext = HttpContext.Current;
httpContext.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
httpContext.Response.ContentEncoding = Encoding.UTF8;
httpContext.Response.Charset = "";
httpContext.Response.AppendHeader(
"Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(fileName, Encoding.UTF8));
httpContext.Response.BinaryWrite(ExcelPlus.GetAsByteArray());
httpContext.Response.Flush();
httpContext.Response.End();
}
else
{
throw new Exception("No Sheet was Found!");
}
}
}
else
{
throw new Exception("No File was Found!");
}
}
catch (Exception ex)
{
throw ex;
}
}
最後，補充一點點：
web項目中的路徑問題：
此方法中需要用到一個做好的excel檔案模版，擷取模版路徑的方法是：
Server.MapPath("virtual path");
注：
HttpRequest hr = System.Web.HttpContext.Current.Request;
string path = hr.CurrentExecutionFilePath;
通過HttpRequest的方法擷取的路徑為浏覽器位址欄裡的路徑
