Razor从输入类型文本中将文本文件读取到内存中

Question

尝试从用户选择的文本文件中将文本读入内存

MODEL：

public HttpPostedFileBase File { get; set; }

查看

<form action="" method="post" enctype="multipart/form-data" id="MyForm">
                @Html.TextBoxFor(m => m.File, new { type = "file" })
                 <input type="submit" name="btnSubmit" id="ProcessAll" value="Process All" />
            </form>

控制器：

[HttpPost]
    public ActionResult FileToFasta(F2FModel model)
{
//Need to read file to a string without uploading it
return View(model);
}

有什么想法？感谢

Answer 1

new StreamReader(model.File.InputStream).ReadToEnd()

Answer 2

使用System.IO命名空间。

var sw = new StreamReader(model.File.InputStream);
var text = sw.ReadToEnd();
sw.Close();
