我在我的应用程序中获得了图像的拖放功能:
似乎HttpPostedFileBase
使用以下代码将文件另存为:
public ActionResult SaveUploadedFile()
{
bool isSavedSuccessfully = true;
foreach (string fileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[fileName];
}
}
我的最终目标是将图像路径存储在我的数据库中,但现在如果我可以将此HttpPostedFileBase
-file 转换为 jpg 并将其存储在项目中的图像文件夹中,我会很高兴。关于如何解决这个问题的任何提示?
编辑:此代码似乎将 HttpPostedFileBase 转换为图像:
public ActionResult SaveUploadedFile()
{
bool isSavedSuccessfully = true;
foreach (string fileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[fileName];
var filename = Path.GetFileName(file.FileName);
var sourceimage = System.Drawing.Image.FromStream(file.InputStream);
img = sourceimage;
}
}
我还添加了一个道具来存储它:
public Image img { get; set; }
编辑:
public HttpPostedFileBase DropImg { get; set; }
public Image img { get; set; }
public ActionResult SaveUploadedFile(string test)
{
bool isSavedSuccessfully = true;
foreach (string fileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[fileName];
DropImg = file;
var filename = Path.GetFileName(file.FileName);
var sourceimage = System.Drawing.Image.FromStream(file.InputStream);
img = sourceimage;
var fullPath = "~/Content/images/drops/" + file.FileName;
file.SaveAs(Server.MapPath(fullPath));
}
if (isSavedSuccessfully)
{
return Json(new { Message = "File saved" });
}
else
{
return Json(new { Message = "Error in saving file" });
}
}
我希望这会将我的图像保存到文件夹中……我错过了什么吗?
