ASP. NET MVC upload file

Recently, I've learned how ASP. NET MVC uploads files by referencing network data. Most basic, not with jquery and other technologies.

1. Define Model

public class Testmodel
{
[Display (Name = "title")]
[Required]
public string Title
{
Get
Set
}
[Display (Name = "content")]
[Required]
[DataType (Datatype.multilinetext)]
public string Content
{
Get
Set
}
public string AttachmentPath
{
Get
Set
}
}

2. Controller

    public class Testcontroller:controller {////GET:/test/public actionresult Upload ()        {return View (); }///<summary>/////</summary>//<param Name= "TM" > Model data </param&        Gt        <param name= "File" > uploaded object with the same parameter name as the upload tag name in view </param>//<returns></returns> [HttpPost] public actionresult Upload (Testmodel TM, HttpPostedFileBase file) {if (file = = nul L) {return Content ("No Files!            "," Text/plain "); } var fileName = Path.Combine (Request.mappath ("~/upload"), Path.getfilename (file.            FileName)); try {file.                SaveAs (FileName); Tm. AttachmentPath = filename;//Get all the Model information TM. AttachmentPath = ". /upload/"+ path.getfilename (file.              FileName); return Content ("Upload successful!                "," Text/plain ");Return redirecttoaction ("Show", TM); } catch {return Content ("Upload exception!            "," Text/plain ");        }} public ActionResult Show (Testmodel tm) {return View (tm); }    }

3. View

3.1 upload.cshtml

@model mvcapplication1.models.testmodel@{    viewbag.title = "Upload";} <! DOCTYPE html>
3.2 show.cshtml
@model mvcapplication1.models.testmodel@{    viewbag.title = "Show";}
