Is there any kind of serializer in .net that can be used to load and save object graphs w/o barfing if unexpected/old elements exist in the serialized data?
I simply want to ignore field/property names that no longer exist in the serialized classes.
such field should simply be set to their default values.
XmlSerializer won't cut it since it only handles hierarchies and real graphs.
SoapFormatter seems like it always crash if unexpected elements are found.
I do know I can implement ISerializable but Im trying to avoid that, I want it to be easy to plug in new elements in the save file in this use case.
I'm hoping there might be some nifty stuff in WCF for this, or that it might be possible to handle this with the soapformatter.
any ideas?

I assume you are using the BinaryFormatter.
Wont ISurrogateSelector help?

How about iterating over the items with a foreach loop?

Are you putting the whole stuff inside a loop which is missing from your above code ? If yes put the message box.Show outside the loop 
Thanks

thanks..I am still struck with loop, could you please provide me template/sample code..it will be good help

Bit hard to give you something exact, would need more info about your app/design but this is the basics:
foreach (Control c in myCollection)
{
if (c.someProperty == true)
{
}
else
{
}
}

Thanks a lot.....I am providing you exact code
DialogResult dlgResult = MessageBox.Show("Removal of this task will also remove following tasks:" + "(" + next_node + ")" + " Do you still want to continue", "Warning", MessageBoxButtons.YesNo, MessageBoxIcon.Warning);
if (!selectedNode.Checked)
if (dlgResult == DialogResult.Yes)
doCheckSibling(next_node, false);
else if (dlgResult == DialogResult.No)
selectedNode.Checked = true;
This will give you better idea and you can tell me exactly how I can use foreach, I am very close to solution I hope this would be my last query...thanks in advance..

I have already told you exactly how to use a foreach, I'm not here to do your work for you and if I was to give you complete code you won't learn anything. You've also provided me with the same snippet from your original post. I suggest you look at my last post, consider what issue you're having and then read the following article: How To Use Google[^]

Hi,
I am setting a Property in a class using the following:
xmloutput.FileName = @"c\projects\text.xml";
Then I use the following to open a new XMLTextWriter;
XmlTextWriter xmlWriter = new XmlTextWriter(_FileName, System.Text.Encoding.UTF8);
However the Filename gets changed to :
D:\\My Documents\\Visual Studio 2005\\Projects\\Scanner\\Scanner\\bin\\Debug\\c\\projects\\text.xml
I cannot understand why the D:\\ etc gets put onto the front of the string. Any help would be appreciated
|
|
|
|
|
Not sure if this is 100% the issue, but I'm assuming 'c' is a drive and not a folder. Set the filename to @"C:\\projects\\text.xml"

When you put a @ in front of the string you don't need \\ to get a \. But otherwise it's correct. There is a : missing in the path.
|
|
|
|
|
Thanks everyone I could not see the wood for the trees. Just spotted the : missing. Thanks again

Because the sting you are passing isn't a valid path so your program thinks it is a relative path and appends it to the current directory of your application.

Hi,
Thanks for the responses. However, c:\projects does exist on my PC and I have also tried @c:\\projects but am still getting the same problem. However if I hard code as in the following it works fine.
XMLDoc.Save(@"c:\projects\text.xml")
|
|
|
|
|
May be it is taking what you gave in the xmlDoc.FileName as the FILENAME and not the actual path. So the batch will be now [Default solutionpath]\FileName.
In the lter case the Save accepts the actuall path to the file and works fine.
May be you can try storing the path differently nad get it to the scene only in the save function
Thanks

c:\projects is a folder, not a file so how can xmlwriter write to it? You need to specify file path. If you need to path of folder for something else try this: @C:\projects\
