本文介绍了一个使用ASP.NET实现的简单文件下载功能。通过提供文件名和文件路径作为参数，该方法可以设置HTTP响应头来触发浏览器下载指定的文件。

#region /// 文件下载
/// <summary>
/// 文件下载
/// </summary>
/// <param name="fileName">文件名</param>
/// <param name="filePath">文件保存路径</param>
public static void FileDown(string fileName, string filePath)
{
FileInfo fileInfo = new FileInfo(filePath);
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);
HttpContext.Current.Response.AddHeader("Content-Length", fileInfo.Length.ToString());
HttpContext.Current.Response.AddHeader("Content-Transfer-Encoding", "binary");
HttpContext.Current.Response.ContentType = "application/octet-stream";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
HttpContext.Current.Response.WriteFile(fileInfo.FullName);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}

#endregion
