Then the interviewer is an idiot.
If the interviewer is going to ask question they must do adequate research that they, at the very least, don't look like a complete fool.
If they offer you the job, think very carefully about whether you actually want to work there or not. Some people get very defensive if you tell them they are wrong. Remember: The mind is like a parachute; it works best when it is open.

I don't know about that. I've seen some minds that are so far open that air just passes straight through them!

Don't be so open minded your brain falls out.

 It's way, way, way too late for most of those people! Their brains have long since been washed down the storm drains...

Yes. It will garbage collect instances of class1 and class2.

Yes, it will. SuppressFinalize just tells the GC to remove the object from the finalization queue. It still gets collected.
The interviewer told you you were wrong?? Doesn't sound like a company I'd want to work for then...

Hi i working at the moment with serialization and i have a simple question.
When is it necessary to implement the ISerializable Interface and when is it enought to mark an klasse as [Serializable] ? 
|
|
|
|
|
Marking a class as [Serializable] means all public members will be autoomatically serialized and deserialized. Uisng the ISerializable interface allows you fine control over this process.
|
|
|
|
|
What do you mean with fine control ?
Do you mean it so,that i have to implement the [ISerializeable] interface then when my class have private members ?
|
|
|
|
|
I don't know where J4amieC got this from, but adding [Serializable()] to a class works perfect for private as well as public members. To exclude a member from serialization you can use [field:NonSerialized()], when you want to upgrade a class with additional members that require to be serialized and maintain backward compatibility with the previous version of your class you can use [field:OptionalField()] on the member. Frankly, I don't ever use the ISerializable interface.
Standards are great! Everybody should have one!

When i only mark a class as [Serializeable] then i got an SerializeException when i deserialize the class wich say that the necessary constuctor of the class is missing.
So thats why i implemented the ISerializeable-Interface with its methodes...
[SecurityPermissionAttribute( SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter )]
void ISerializable.GetObjectData( SerializationInfo info, StreamingContext context ) {
this.GetObjectData( info, context );
}
public override void GetObjectData( SerializationInfo info, StreamingContext context ){
info.AddValue( "member", member );
...
}
...and the necessary constructor...
public ClassName( SerializationInfo info, StreamingContext context ){
member = info.GetValue( "member", typeof( member ) );
...
}
and cause that works fine was i thinking...
"Everytime when i wanna serialize a class i have to implement the ISerializeable-interface"
...but i read somewhere that it is enough in some cases to mark a class as [Serializeable].
BTW: i use BinaryFormatter to serialize and deserialize my classes.

Marking your class [Serializable()] is only enough if all of your class members are themselves serializable: The exception you're getting is because one of your members doesn't support serialization.
If you don't really need the member just mark it as [field:NonSerialized()] and the exception will go away.
Otherwise, make sure it supports serialization. You can do this by marking the class as [Serializable()] itself. Determine which members should be saved, mark all others as [field:NonSerialized()], repeat the operation for your member's memberclasses (and enumerations), and so on, until you reach a class with only primitive types.
This mechanism provides an easier, faster and less errorprown way to serialize, I prefer it over ISerialzable...

Can a ToolStripProgressBar/progressbar take a float value to get incremented? If so then how?

No, it can't.

i need an event in datagridview that will be called for every row that is binded to the grid in windows application. is there an event?
|
|
|
|
|
Why do you need the event? there is always an option to access the data that is binded to the datagrid. If you populate your grid with a dataset try
<code>
foreach (System.Data.DataRow dr in dsModApp.Tables[0].Rows)
{
myList.Add(dr.ItemArray[0].ToString());
}
</code>
here i retireve the first column that is my select statement and thus position [0] in the dataset that is returned. Then i add the information to an arraylist for other purposes. hope it helps

Hi,
You can use the RowsAdded event on the grid. It is fired when you add a row to the grid... It includes when you bind a dataset, then it is fired for every row.

how to run console application in command prompt.
the keywords to run...
like csc Program.cs...........
whats it i dont know exactly how to do it.
|

After you have compiled the application, you will find the .exe file in the bin folder. That is the program that you run.

csc compiles the cs file. The exe will be generated. You then run the exe.

You know there is a Main method like this;
static void Main(string[] args)
args is an array which contains commands of your program.exe
check this one;
static void Main(string[] args)<br />
{<br />
if (args[0] == "hello")<br />
{<br />
Console.WriteLine("args[0] = {0}", args[0]);<br />
}<br />
if (args[1] == "world")<br />
{<br />
Console.WriteLine("args[1] = {0}", args[1]);<br />
}<br />
}
in this case, write "programpath\yourprogramname.exe hello world" and viola!
