我有一个asp.net mvc应用程序,我可以一次上传多个图像,并且工作正常,但我有一个问题,从原件创建缩略图。
以下是代码:
[HttpPost]
public ActionResult SaveUploadedFile()
{
bool isSavedSuccessfully = true;
string fName = "";
try
{
foreach (string fileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[fileName];
fName = file.FileName;
if (file != null && file.ContentLength > 0)
{
var originalDirectory = new DirectoryInfo(string.Format("{0}Images", Server.MapPath(@"\")));
string pathString = Path.Combine(originalDirectory.ToString(), "Gallery");
string pathString2 = Path.Combine(originalDirectory.ToString(), "Gallery\\Thumbs");
//var fileName1 = Path.GetFileName(file.FileName);
bool exists = Directory.Exists(pathString);
bool exists2 = Directory.Exists(pathString2);
if (!exists)
Directory.CreateDirectory(pathString);
if (!exists2)
Directory.CreateDirectory(pathString2);
var path = string.Format("{0}\\{1}", pathString, file.FileName);
file.SaveAs(path);
//WebImage img = new WebImage(file.InputStream);
WebImage img = new WebImage(fileName);
//if (img.Width > 1000)
img.Resize(100, 100);
img.Save(pathString2);
}
}
}
catch (Exception ex)
{
isSavedSuccessfully = false;
}
if (isSavedSuccessfully)
{
return Json(new { Message = fName });
}
else
{
return Json(new { Message = "Error in saving file" });
}
}
所以基本上file.SaveAs(path);
是最后一行有效,我实际上保存了图像,但在那行之后我尝试创建并保存大拇指但它不起作用(我确实得到了Thumbs
文件夹之前创建的。)
我也得到Error in saving file
响应,但那是因为我正在尝试创建并保存大拇指,如果我删除它然后我没有得到它,我不知道如何返回实际的错误实际看到错误是什么。
答案 0 :(得分:0)
答案是:
var path2 = string.Format("{0}\\{1}", pathString2, file.FileName)
WebImage img = new WebImage(file.InputStream);
img.Resize(250, 250);
img.Save(path2);
