Question

我发布了一张带有图片的表单。并在我的控制器中接收

var image=Request.Files["hiddenUploadButton"];

现在我想将我的图像转换为Stream。怎么做？

Answer 1

var stream  = Request.Files["hiddenUploadButton"].InputStream;

请参阅this link。

也许你想做this之类的事情？

Answer 2

 if you want to save file try following code snippet

 HttpPostedFile file = Request.Files["myFile"];

    //check file was submitted
    if (file != null && file.ContentLength > 0)
    {
        string fname = Path.GetFileName(file.FileName);
        file.SaveAs(Server.MapPath(Path.Combine("~/App_Data/", fname)));
    }

如何转换为流，

     HttpPostedFile file = Request.Files["myFile"];
var FileLen = file .ContentLength;
   byte[] input = new byte[FileLen];
  System.IO.Stream MyStream;
   // Initialize the stream.
   MyStream = file .InputStream;

   // Read the file into the byte array.
   MyStream.Read(input, 0, FileLen);

如何将提交的图像转换为流？
