將上傳的文件保存到服務器文件系統，並使用ASP.NET MVC5在sql server數據庫中保存文件路徑

-1

我正在研究保存db.table文件屬性的ASP.NET MVC5應用程序，並同時上傳文件夾內的實際文件。它工作正常，但我不知道如何在上傳文件時將我的文件路徑保存在數據庫中。我想將上傳的文件路徑存儲在數據庫中，以便能夠使用路徑來檢索它。非常感謝！！控制器是：將上傳的文件保存到服務器文件系統，並使用ASP.NET MVC5在sql server數據庫中保存文件路徑

[HttpPost] 
    [ValidateAntiForgeryToken] 
    public ActionResult Create([Bind(Include = "LearnObj_ID,LearnObj_No,LearnObj_Title,LearnObj_Description,LearnObj_Keyword,LearnObj_Language,LearnObj_CreatorName,LearnObj_CreatorLastName,LearnObj_Email,LearnObj_Version,LearnObj_Status,LearnObj_Date,LearnObj_Coverage,LearnObj_Contributor,LearnObj_Format,LearnObj_Location,LearnObj_Subject,LearnObj_Relation,LearnObj_Source,LearnObj_Publisher,LearnObj_Type")] Learning_Object learning_object, HttpPostedFileBase UploadTheFile) 
    { 

      if (UploadTheFile != null && UploadTheFile.ContentLength > 0) 
      { 
       // extract only the fielname 
       var fileName = Path.GetFileName(UploadTheFile.FileName); 
       // store the file inside ~/Content/LearnObject-Repository folder 
       var path = Path.Combine(Server.MapPath("~/Content/LearnObject-Repository"), fileName); 
       UploadTheFile.SaveAs(path); 

       here, I want to save the file path(as above) in the db.Learning_Object 
       the field is LearnObj_Source 

      } 


      if (ModelState.IsValid) 
      { 
       db.Learning_Object.Add(learning_object); 
       db.SaveChanges(); 
       return RedirectToAction("Index"); 
      } 

      return View(learning_object); 
     } 
     } 
    //------- end of uploading ---->

也許它會幫助，如果你真的問了一個問題 –

感謝您的答覆，我會編輯我的問題。 – user3521892

因爲，你的數據庫不應該依賴於服務器的路徑，你可以這部分保存爲路徑

var fileNameToSaveInDB = @"Content/LearnObject-Repository/"+fileName

然後每當你想加載文件，你可以這樣做

Path.Combine(Server.MapPath("~",Table.FileNameField)

Path.Combine（@「Content/LearnObject-Repository」，fileName）不起作用。我有var path = Path.Combine（Server.MapPath（「〜/ Content/LearnObject-Repository」），fileName）;在我的控制器中。 – user3521892

@ user3521892我已編輯我的答案 – RezaRahmati

不能在db.Learning_Object表中添加一個nvarchar列，並將路徑保存爲文本？你可以做一個存儲過程，這樣

@path nvarchar(MAX) 
as 
INSERT INTO db.Learning_Object (path,column2,column3,...) 
VALUES (@path,value2,value3,...)

然後（如果你使用LINQ）調用存儲過程並插入要保存這樣的路徑。

LearningObjectDataContextClass db = new LearningObjectDataContextClass(); 
db.InsertPath(pathtoinsert);
