不能隐式将System.Windows.Forms.Form转换为'String'

Question

嘿，所以我有一个模式弹出表单，我必须在其中上传文件并将数据发布到数据库。在控制器中，我通过FormCollection检索值。当我尝试用表单集合获取输入字段时，我得到了这样的错误：无法隐式转换System。Windows。表格。表单为"字符串"。这是我的代码：

控制器

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(FormCollection formCollection, HttpPostedFileBase upload, AAC_procedure_document_types model,NgarkoDokument ngarkoDok)
{
try
{
if (ModelState.IsValid)
{
if (upload != null && upload.ContentLength > 0)
{
var file = new AAC_procedure_documents
{
Emer_Dokumenti = System.IO.Path.GetFileName(upload.FileName),
Lloji_File = model.Emri_llojit,
Content_Type = upload.ContentType
};
using (var reader = new System.IO.BinaryReader(upload.InputStream))
{
file.Permbajtje_Dokumenti = reader.ReadBytes(upload.ContentLength);
}
ngarkoDok.AAC_procedure_documents = new List<AAC_procedure_documents> { file };
}
AAC_procedure_documents_location lokacion = new AAC_procedure_documents_location();
lokacion.Rafti = formCollection["Rafti"];
lokacion.Zyra = formCollection["Zyra"].ToString();
lokacion.Nr_Kutise = Convert.ToInt32(formCollection["Nr_Kutise"]);
db.AAC_procedure_documents_location.Add(lokacion);
db.SaveChanges();
return RedirectToAction("Dokumenti");
}
}
catch (RetryLimitExceededException /* dex */)
{
//Log the error (uncomment dex variable name and add a line here to write a log.
ModelState.AddModelError("", "Unable to save changes. Try again, and if the problem persists see your system administrator.");
}
return View(formCollection);
}

Answer 1

FormCollection的命名空间必须是System。网状物Mvc而不是System。Windows。表格。查看您的usings并删除System。Windows。表单。。。

FormCollection类存在于两种技术中，WindowsForm和Web。
