Comment sauvegarder un fichier sur le disque?

Question

Voici mon contrôleur:

[HttpPost] 
    public ActionResult Index(HttpPostedFileBase excelFile) 
    { 

     /*Somewhere here, I have to save the uploaded file.*/ 

     var fileName = string.Format("{0}\\{1}", Directory.GetCurrentDirectory(), excelFile.FileName); 
     var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName); 

     var adapter = new OleDbDataAdapter("SELECT * FROM [workSheetNameHere$]", connectionString); 
     var ds = new DataSet(); 
     adapter.Fill(ds, "results"); 

     DataTable data = ds.Tables["results"]; 

     return View(); 
    } 

Answer 1

Ceci est une façon de le gérer si vous recevez des fichiers téléchargés.

string nameAndLocation = "~/UploadedFiles/" + hpf.FileName; 
hpf.SaveAs(Server.MapPath(nameAndLocation)); 

Answer 2

Avez-vous essayé HttpPostedFileBase.SaveAs méthode?

Answer 3

[HttpPost] 
public ActionResult Index(HttpPostedFileBase excelFile) 
{ 
    /*Somewhere here, I have to save the uploaded file.*/ 

    var fileName = string.Format("{0}\\{1}", Directory.GetCurrentDirectory(), excelFile.FileName); 

    excelFile.SaveAs(fileName); 

    //... 
}
