The first stage of my project is to ask the customer if they want fries with that.
The next stage involves standing around with a vacant expression. (For extra credit, I let a little bit of drool dangle from the side of my mouth).
The final stage is to get the order wrong.

Hi. Is there any ways/ APIs to determine how many references of a certain object/ class a C# program creates/ uses during it's life cycle?
Suppose there's a class Person and in my program several references to Person objects are made. How to determine the number of Person references in my program?
Thanks.

Not sure about APIs etc., but the obvious one is to maintain a static int as part of your class and increment it for each constructor. This doesn't "uncount" them when they are GCed though, so it is a total count, rather than a shapshot.

Yeah, instance counting is easy. BTW: you could decrement the counter in a finalizer.
However reference counting is basically impossible, a reference can be copied without the class or object being aware of that.
Person person1=new Person();
Person person2=person1;

Yeah, that's my point.

That's a way. But consider the following. One object is constructed, but two references.
Person p = new Person();
Person q = p;
How to track this?

you can't, there is nothing to support that in .NET
The GC is based on (a slightly conservative) reachability or "life" analysis, not on reference counting.
why would you need a reference count?
if only for one or a few classes of your own, you could try and implement it yourself, including an override for the = operator. Not sure you can get it all tight though.

you can try this,
DateTime d1 = DateTime.Today;
DateTime d2 = DateTime.Today.AddDays(1);
TimeSpan ans = d2.Subtract(d1);
If I didn't get your problem plz explain it.

public new static object GetIPictureDispFromPicture(System.Drawing.Image image)
{
System.Drawing.ImageConverter converter2 = new System.Drawing.ImageConverter();
byte[] arraybyt2 = (byte[])converter2.ConvertTo(image, typeof(byte[]));
System.Drawing.Image imageToConvert = System.Windows.Forms.AxHost.GetPictureFromIPicture(System.Windows.Forms.AxHost.GetIPictureFromPicture(image));
System.Drawing.ImageConverter converter = new System.Drawing.ImageConverter();
byte[] arraybyt = (byte[])converter.ConvertTo(imageToConvert, typeof(byte[]));
return System.Windows.Forms.AxHost.GetIPictureFromPicture(image);
}
The function receives a Image that needs to be converted to an ipicture. I found out that during change the image to a ipicture and back to image the size of the array of bytes are different. How come the size of the arraybyt1 and arraybyt2 are different. I'm creating a checksum of the array from bytes and therefor the checksum is also different?

I am not familiar with IPicture, and therefore this is very much a guess.
Perhaps Image stores data that IPicture doesn't, or vice versa. For example, different sized headers or one stores palette information and one doesn't.
Most image formats have their specifications out on the web somewhere, have a play with google.

How can i load in a XmlDocument an xml file (from text file) that in the tag contain any type of char ? How can encode this ?
If my file contain char as "&" or "°" there is an exception (Xml.XmlException Errore durante l'analisi di EntityName).
I try with this but don't work:
Encoding enc = Encoding.ASCII;
FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read, FileShare.None);
StreamReader sr = new StreamReader(fs,enc);
string response = sr.ReadToEnd();
XmlDocument xml = new XmlDocument();
xml.LoadXml(response);
fs.Close();
sr.Close();
The exception is Xml.XmlException Errore durante l'analisi di EntityName.

Well as far as I know it is not allowed to use all chars in entity-names. There is a strict rule for tag-names. Maybe you could post a bit of your xml-file, so that we can identify the problem.

Sebastian

The problem isn't the tag-names but their content.
The exception occur when in the content of a tag (<tag> abc & avc n° ) there are particular char as & or °

You could replace all special characters with their escape characters before reading the xml. Maybe this helps.
|
|
|
|
|
How can i replace it ? can you give me an example of code ?
|
|
|
|
|
Not the best method but maybe
response = response.Replace( "&", "&");
By the way, do you have an xml-declaration in your file (sort of <?xml version="1.0" encoding="UTF-8"?> )?
