前段时间我在 MVC4 视觉工作室工作。我在这方面真的很新，希望有人能帮助我。
我的网站中有一个输入类型=“文本”和输入类型=“文件”的表单。
我想在我的数据库中插入一个带有多个图像上传的新项目。
我尝试在视图、控制器和模型中做到这一点。
我搜索了一些东西并找到了一个对上传几张图片有很大帮助的代码。
但我想要的是当我点击按钮上传所有图像并将其他字段的所有信息和所有图像的文件名插入到我的表中。所以我可以在另一个页面中选择与此 ID 关联的所有图像。
希望有人可以帮助解决这个问题。
这是我的代码：
提前致谢
看法：
@using (Html.BeginForm("Uploading", "AdicionarRevista", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<label for="file">Nome da Empresa:</label>
<input type="text" name="Name" id="nome" /><br />
<label for="file">Titulo da Revista:</label>
<input type="text" name="Title" id="titulo" /> <br />
<label for="file">Upload:</label>
<input type="file" name="ImageUploaded" id="btnUpload" multiple="multiple" accept="image/*" /> <br />
<button type="submit" id="Upload">Upload</button>
}
控制器：
[HttpPost]
public ActionResult Uploading(ImageModel infouploadimage)
{
for (int i = 0; i < Request.Files.Count; i++)
{
if (Request.Files[i].ContentLength > 0)
{
HttpPostedFileBase uploadedFile = Request.Files[i];
string fileName = Guid.NewGuid().ToString();
string serverPath = Server.MapPath("~");
string imagesPath = serverPath + "Content\\Images\\";
string thumsise = Path.Combine(imagesPath, "Thumb" + fileName);
string thumbPath = Path.Combine(imagesPath, "Thu" + fileName);
string fullPath = Path.Combine(imagesPath, "Full" + fileName);
string Bigpath = Path.Combine(imagesPath, "big" + fileName);
string Bigpatha = Path.Combine(imagesPath, "biga" + fileName);
string Bigpathb = Path.Combine(imagesPath, "bigb" + fileName);
string Bigpathc = Path.Combine(imagesPath, "bigc" + fileName);
ImageModel.ResizeAndSave(thumsise, fileName, uploadedFile.InputStream, 80, true);
ImageModel.ResizeAndSave(thumbPath, fileName, uploadedFile.InputStream, 100, true);
ImageModel.ResizeAndSave(fullPath, fileName, uploadedFile.InputStream, 500, true);
ImageModel.ResizeAndSave(Bigpath, fileName, uploadedFile.InputStream, 200, true);
ImageModel.ResizeAndSave(Bigpatha, fileName, uploadedFile.InputStream, 250, true);
ImageModel.ResizeAndSave(Bigpathb, fileName, uploadedFile.InputStream, 150, true);
ImageModel.ResizeAndSave(Bigpathc, fileName, uploadedFile.InputStream, 50, true);
}
}
return RedirectToAction("Index", "Home");
}
