这是在Control里使用的代码，是在后台管理需要上传图片时使用的，不过我在这犯了一个错误， Request.Files[inputName];inputName名字中的大小写
<input type="file" name="image">应该与model里的字段的名字一致
if (Request.RequestType == "POST")
{
foreach (string inputName in Request.Files.AllKeys)
{
HttpPostedFileBase file = Request.Files[inputName];
//存入文件
if (file.ContentLength > 0)
{
PropertyInfo pro = model.GetType().GetProperty(inputName);
string proValue = (string)pro.GetValue(model, null);
if (!string.IsNullOrWhiteSpace(proValue))
{
Common.FileUpload.DeleteFile(proValue);
}
string fileName = Common.FileUpload.UploadFile(file);
pro.SetValue(model, fileName, null);
}
}
}
public static string UploadFile(HttpPostedFileBase file)
{
// Check if we have a file
if (null == file) return "";
// Make sure the file has content
if (!(file.ContentLength > 0)) return "";
string fileName = file.FileName;
string fileExt = Path.GetExtension(file.FileName);
// Make sure we were able to determine a proper
// extension
if (null == fileExt) return "";
char DirSeparator = '/';
string FilesPath = string.Format("{0}team{0}{1}{0}{2}{3}{0}", DirSeparator, DateTime.Now.Year, DateTime.Now.Month.ToString().PadLeft(2, '0'), DateTime.Now.Day.ToString().PadLeft(2, '0'));
string PhysicalPath = HttpContext.Current.Server.MapPath(FilesPath);
// Check if the directory we are saving to exists
if (!Directory.Exists(PhysicalPath))
{
// If it doesn't exist, create the directory
Directory.CreateDirectory(PhysicalPath);
}
// Set our full path for saving
string path = PhysicalPath + fileName;
// Save our file
file.SaveAs(Path.GetFullPath(path));
// Return the filename
return FilesPath + fileName;
}
public static void DeleteFile(string fileName)
{
if (!string.IsNullOrWhiteSpace(fileName))
{
// Don't do anything if there is no name
if (fileName.Length == 0) return;
// Set our full path for deleting
string path = HttpContext.Current.Server.MapPath(fileName);
// Check if our file exists
if (File.Exists(Path.GetFullPath(path)))
{
// Delete our file
File.Delete(Path.GetFullPath(path));
}
