本文实例讲述了Asp.net获取服务器指定文件夹目录文件并提供下载的方法。分享给大家供大家参考。具体实现方法如下：

复制代码 代码如下:string dirPath = HttpContext.Current.Server.MapPath("uploads/");

if (Directory.Exists(dirPath))

{

//获得目录信息

DirectoryInfo dir = new DirectoryInfo(dirPath);

//获得目录文件列表

FileInfo[] files = dir.GetFiles("*.*");

string[] fileNames = new string[files.Length];

//临时数据表

DataTable dt = new DataTable();

dt.Columns.Add("FileName");

foreach (FileInfo fileInfo in files)

{

DataRow dr = dt.NewRow();

dr["FileName"] = fileInfo.Name;

dt.Rows.Add(dr);

}

Repeater1.DataSource = dt;

Repeater1.DataBind();

}

if (e.CommandName == "down")

{

try

{

string DownloadFileName = "~/uploads/" + e.CommandArgument.ToString();//文件路径

string filepath = Server.MapPath(DownloadFileName);

string filename = Path.GetFileName(filepath);

FileInfo file = new FileInfo(filepath);

Response.Clear();

Response.ContentType = "application/octet-stream";

Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8));

Response.AddHeader("Content-length", file.Length.ToString());

Response.Flush();

Response.WriteFile(filepath);

}

catch

{

Response.Write("<script>alert('没有找到下载的源文件')</script>");

}

}

希望本文所述对大家的asp.net程序设计有所帮助。
