写真とユーザータグを含むxmlファイルがあります。これで、ローカルPCから画像を参照してWebアプリケーションのimgフォルダーにアップロードするWebサイトができました。画像を正常にアップロードした後、Webサイトを更新してWebサイトに表示する必要があります。しかし、問題は、新しいブラウズ画像の xml タグが生成されないため、ウェブサイトにアップロードされた画像がウェブサイトに表示されないことです。
以下はコードビハインドです。
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
// Before attempting to save the file, verify
// that the FileUpload control contains a file.
if (FileUpload1.HasFile)
{
// Call a helper method routine to save the file.
SaveFile(FileUpload1.PostedFile);
XmlDocument doc = new XmlDocument();
//string path = @"C:\Users\khant\Documents\visual studio 2012\Projects\UploadImageRetrieve\UploadImageRetrieve\photos.xml";
doc.Load("C:\\Users\\khant\\Documents\\visual studio 2012\\Projects\\UploadImageRetrieve\\UploadImageRetrieve\\photos.xml");
string filenm = FileUpload1.FileName;
XmlElement user = doc.CreateElement("user");
XmlElement photo = doc.CreateElement("photo");
XmlText phototext = doc.CreateTextNode("img/"+filenm);
//doc.SelectSingleNode("/appSettings/add").Attributes["value"].Value = "hello";
//doc.SelectNodes("/appSettings/add").Item(2).Attributes["value"].Value = "hello";
photo.AppendChild(phototext);
user.AppendChild(photo);
doc.Save("C:\\Users\\khant\\Documents\\visual studio 2012\\Projects\\UploadImageRetrieve\\UploadImageRetrieve\\photos.xml");
}
else
// Notify the user that a file was not uploaded.
UploadStatusLabel.Text = "You did not specify a file to upload.";
}
void SaveFile(HttpPostedFile file)
{
// Specify the path to save the uploaded file to.
string savePath = "C:\\Users\\khant\\Documents\\visual studio 2012\\Projects\\UploadImageRetrieve\\UploadImageRetrieve\\img\\";
// Get the name of the file to upload.
string fileName = FileUpload1.FileName;
// Create the path and file name to check for duplicates.
string pathToCheck = savePath + fileName;
// Create a temporary file name to use for checking duplicates.
string tempfileName = "";
// Check to see if a file already exists with the
// same name as the file to upload.
if (System.IO.File.Exists(pathToCheck))
{
int counter = 2;
while (System.IO.File.Exists(pathToCheck))
{
// if a file with this name already exists,
// prefix the filename with a number.
tempfileName = counter.ToString() + fileName;
pathToCheck = savePath + tempfileName;
counter++;
}
fileName = tempfileName;
// Notify the user that the file name was changed.
UploadStatusLabel.Text = "A file with the same name already exists." +
"<br />Your file was saved as " + fileName;
}
else
{
// Notify the user that the file was saved successfully.
UploadStatusLabel.Text = "Your file was uploaded successfully.";
}
// Append the name of the file to upload to the path.
savePath += fileName;
// Call the SaveAs method to save the uploaded
// file to the specified directory.
FileUpload1.SaveAs(savePath);
}
}
どこが間違っているか教えてください。
ありがとう。
