C# - How To Serialize Only Some Properties In .Net
Mar 15, 2010
This is for a web project so i have several classes that inherit from Web.UI.
I only want to serialize very particular properties (basically, only local properties)
I'm aware of the XMLIgnore property that can be placed on a property to ignore items, but this won't work in my context since that would require modifying a bunch of stuff that i really don't want to modify (and probably can't).
So how do i tell the xml serializer to ignore everything except for X and Y or tell it to seralize just X and Y?
i could just create my own xml in a string builder or something and if that's the only way, so be it. however i'm looking for a method that will employ the built in XML stuff.

If a class is serialized and has events fired from it that are handled on a form you get the error "Form1 cannot be serialized" in c# you can use (to work around this):

I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)

In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()
End Sub

The following defines the structures I am attempting to serialize. I think I have the xml decoration correct - but the errors I'm receiving (see below) don't really give me much information.

I need a way to transfer a compiled assembly from client to the server and be able to store that in the database or in a file in such a way that I can grab those bytes on the "to" side and re-load assembly. Is there a way to do it. To clarify, I have a winforms application that will generate code and compile it based on some metadata. Now I need to be able to transfer this to a web site and store it somehow, but I don't want a dll (because it can be de-compiled). I would then have a "server" program on the to side, that would load this in memory. I could just transfer encrypted source code, but I thought I could just transfer compiled assembly.

I am having an issue using BinaryFormatter.Serialize. I have this generic extension method to "clone" an object via binary serialization:
[Code]...
This is killing performance. Anything more that about 7 or 8 clones brings the app to a halt. Why would this happen? The USING block ought to ensure the MemoryString is disposed of, right? Shouldn't a new MemoryString be created each time? I would think since the same original Mode object is the source for the serialization, the MemoryString length would be the same.

I have an XML document that I am deserializing (VB .NET 3.5 Framework), changing some values, and the serializing again. The original document has several XML Comments in it. When I go through all the deserialize/serialize all of the comments are lost. Is there a way to preserve the comments? If not, is there a way to add comments on serialization without having to walk through with the writer and manually add all of the comments back in the appropriate place?

I have a 3D Engine which renders a 3D World onto any vb.net object with an HWND(Handle) -Picturebox or Form using Direct3D.What I'd like to do is stream that image over my LAN. I know its probably a weird idea, but I have a plan.Since the image is 'rendered' onto the object, the objects 'Image' Property is null, so sending that to a byte array doesn't do any good.Now, I've tried using the picturebox.drawtobitmap function, but it is far to slow for what I'm intending.I've used several functions in the Graphics control to try and get the image data off that picturebox, but to no avail.I've even tried sampling the surface data from Direct3D but none of these objects are able to be converted to a byte array.

when it serialize the data table on the last line,it got an error:
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Web.Extensions.dll Additional information: A circular reference was detected while serializing an object of type 'System.Globalization.CultureInfo'I even make the simplest datatable with only 1 column and 1 row, but it just won't serialize it?

It is my first time trying to serialize an array into xml list. Couldn't really find a nice tutorial out there on xml.
I have
dim Array() as integer = {1,2,3}
dim Value() as string= {Value1,Value2,Value3}
When the array is serialize, i guess, i want to try to get the format to look like below:
<p data="Value1">1</p>
<p data="Value2">2</p>
<p data="Value3">3</p>
How o it serialize into this format, and de-serialize back into an array?

How do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load .INI code.I just wondered if I can do it in one call, or a simple for loop iterating over all controls on the form.Btw, I use only simple controls like edit box, radio button, combo box, checkd listbox, the most complex thing I have is a datagrid, but even that is not linked to a databse.Accepted answer "can't. I will probably code my own, along the lines of ...

maybe later add left/top/height/width/enabled/visible, etc, bu tfor not th econtrol name an its "value" are enough (text, value, lines, checked?, etc)
