如何在mvc中上传.pdf，.docx和.doc的文件文件类型 [英] How to upload a file file type of .pdf, .docx and .doc in mvc

问题描述

您好我可以轻松上传任何类型的文件，但我的要求是上传.pdf，.doc，.docx扩展名文件。



我有尝试但没有服用....请帮助我...

解决方案

以下链接为您提供了一个工作示例：http：//stackoverflow.com/questions / 4328947 / limit-file-format-when-using-input-type-file

我相信这会有所帮助

  public   void 插入（FileloadView doc）
 {
 使用（ var  rep =  new  FileloadRepository（））
 {
 rep.Insert（ConvertToDocuments（doc））; 
} 
} 
 
 私有 静态 FileLoad ConvertToDocuments （FileloadView doc）
 {
 FileLoad FileUplodModel =  new  FileLoad（）; 
  foreach （ var  item  in  doc.File）
 {
  byte  [] uploadFile =  new  字节 [item.InputStream.Length]; 
 item.InputStream.Read（uploadFile， 0 ，uploadFile.Length）; 
 FileUplodModel.FileName = item.FileName; 
 FileUplodModel.File = uploadFile; 
 
} 
  return  FileUplodModel; 
} 

然后在控制器中应用以下代码



private readonly FileloadBusiness _db = new FileloadBusiness（）;



public ActionResult Creating（）

{

返回查看（）;

}





[HttpPost]

public ActionResult Creating（FileloadView doc）

{

try

{

_db.Insert（doc）; < br $>


返回RedirectToAction（已上传）;

}

catch（例外e）

{



返回查看（）;

}

}



并将其添加到您的视图中

@using（Html.BeginForm（null，null，FormMethod.Post，new {enctype =multipart / form-da ta}））

{

@ Html.AntiForgeryToken（）

---

@ ViewBag.size

@ Html.ValidationSummary（true， ，new {@class =text-danger}）

@TempData [successfull]

@ Html.Label（文件名，htmlAttributes：new {@class =control-label col-md-2，style =width：150px}）

@ Html.EditorFor（model => model.FileName，new {htmlAttributes = new {@class =form-control}}）

@ Html.ValidationMessageFor（model => model.FileName，，new {@class = text-danger}）

@ Html.LabelFor（x => x.File）

@ Html.TextBoxFor（x => x.File，new {type =file， multiple =true}）

@ Html.ValidationMessageFor（x => x.File）

< input type =submitvalue =Uploadclass =btn btn-default/>

}

解决方案

The following link gives you a working sample: http://stackoverflow.com/questions/4328947/limit-file-format-when-using-input-type-file

I believe this would help

public void Insert(FileloadView doc)
{
    using (var rep = new FileloadRepository())
    {
        rep.Insert(ConvertToDocuments(doc));
    }
}

private static FileLoad ConvertToDocuments(FileloadView doc)
{
    FileLoad FileUplodModel = new FileLoad();
    foreach (var item in doc.File)
    {
        byte [] uploadFile = new byte[item.InputStream.Length];
        item.InputStream.Read(uploadFile, 0, uploadFile.Length);
        FileUplodModel.FileName = item.FileName;
        FileUplodModel.File = uploadFile;

    }
    return FileUplodModel;
}

and then apply the following code in the controller

private readonly FileloadBusiness _db = new FileloadBusiness();

public ActionResult Creating()
{
return View();
}


[HttpPost]
public ActionResult Creating(FileloadView doc)
{
try
{
_db.Insert(doc);

return RedirectToAction("Uploaded");
}
catch (Exception e)
{

return View();
}
}

And add this to your View
@using (Html.BeginForm(null, null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.AntiForgeryToken()

---

@ViewBag.size
@Html.ValidationSummary(true, "", new { @class = "text-danger" })

@TempData["successfull"]
@Html.Label("File Name", htmlAttributes: new { @class = "control-label col-md-2", style = "width: 150px" })

@Html.EditorFor(model => model.FileName, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.FileName, "", new { @class = "text-danger" })

@Html.LabelFor(x => x.File)
@Html.TextBoxFor(x => x.File, new { type = "file", multiple = "true" })
@Html.ValidationMessageFor(x => x.File)

<input type="submit" value="Upload" class="btn btn-default" />

}
