第一種方式:
最簡單的就是返回一個file類型的數據即FilePathResult類型的對象
string serverPath = ConfigurationManager.AppSettings["file.disk.path"];
string name = Path.GetFileName(path);
return File(serverPath + path, mime, name);
第二種方式:
string serverPath = ConfigurationManager.AppSettings["file.disk.path"];
FileInfo file = new FileInfo(serverPath + path);
if (file.Exists)
{
Response.ClearContent();
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "text/plain";
Response.TransmitFile(file.FullName);
Response.End();
}
