Is there performance drop? I use a lot of Struct in some of mine programs when I needed to hold a lot of Data structure within array (Not using PInvoke or accessing COM object). Is it better to use struct or class?

You might, under certain circumstances use more memory.
See
http://msdn.microsoft.com/en-us/library/ah19swz4(VS.71).aspx[^]
The things to note are (Quotes directly from above):
1) Struct are value types. Classes are reference types.
2) Structs have no inheritence (other than object).
3) "The struct type is suitable for representing lightweight objects such as Point [e.g. a Cartesian Co-ordinate]"
4) "Unless you need reference type semantics, a class that is smaller than 16 bytes may be more efficiently handled by the system as a struct."
C# is very different to c++ in this matter, I've been developing C# for about 8 years now, and have never needed a struct (though I have used them from 3rd party stuff).

Is there a performance hit when utilizing a List<class> versus a class[array] (and dynamically sizing this array)?
|
|

Both are held on the heap, so I don't think there won't be much of a performance hit, however if performance is an issue, you could benchmark for yourself.
Generally, IMO, unless you have massive arrays or massive objects performance has never been a worry and even if this is the case good design normally mitigates againt this. Modern machines are fast and have plenty of memory (even if this is restricted by the .net framework) so code readabilty is more of a factor in my experience (this would definately go down with an array that needs resizing). I'm not saying that performance shouldn't be considered, I just think that getting clean code first is better, then run the optimizers over the code, and if you see any bottlenecks really work at those, optimizing too soon (which often equals unecessarilty) really wrecks good code.
Additionally, if the array is frequently resized, this can use up resources as the array is copied and re-sized (and hence my benchmarking suggestion above).

I agree with your ideology. Thanks for explaining.
When an array is re-sized, the data is actually copied/recreated? Are you sure about this?
|
|
|
|
|
Due to the way arrays are implemented they cannot directly resized.
Array.Resize[^] provides resize functionality, but it actually does a copy underneath (as if you created an array of the new size and copied the items across) so the array instance actually changes.

Thanks for your reply.
This hit on performance (array.resize()) is less than the (probable) lower performance of a List<>? However, if array.resize() was never called, an array would be more optimal?

No (or not much) to the first, yes to the second. It really depends upon what you are doing to determine which is most efficient, and that can only be done through testing. If my memory serves, in earlier versions of the famework (2.0) there was a noticable performance gap between List<T> and T[]. This was closed up in 3.0, so the performances are similar. I could be confusing this with .NET Reflection however 
Using the lists is considered good practice as it is easier to use, also these are more widespread so developers are used to seeing the code.
The real answer to your question I suppose is to write the code using List and judge performance from there. If the performance of your code is poor, run a profiler to see if it is the list operations ar e causing it. If so, replace your code with arrays and see what happens.

arrays in C# are homogeneous, they can't hold different types, unless you declare them to hold a common type (in the extreme: object) which isn't a good idea. Create your own element type and keep it a one-dimensional array; in simple cases you might be well of by using a Dictionary (requires unique keys).

Hi all
I am using stringbuilder to create a printscreen and email. It is working well. Now I am trying to create a CSV file too. Sothat we can insert the data in SQL Database.
At the moment it does not create the csv yet. It is only printing on Screen and sending email. I want to add more code which will send me a CSV file when user fillouts the application.
Can you pls look at the code and help me where should i add new code to achive that?
Thanks

hey, I'm having a c# console application which deletes all the files in the server which are 5 days older. for the accessing the server shared path, we need give the user credentials, i don't know where and how to add the authentication part. please helplp me...
Thanks in advance.

Hi all
I have a problem that became huge.
I want to make a backup from my database and if i attach my database to microsoft sql 2005 and use this connectionstring i can backup from my database correctly:
string connectionstring="Data Source=.;DataBase=mydatabase;Integrated Security=true"
but when i detach it from microsoft sql 2005 and add it to SQLEXPRESS and use SQLEXPRESS of visual studio by this connectionstring=@"Data Source=.\SQLEXPRESS;AttachDbFilename=" + Application.StartupPath + "\\Data\\mydatabase.mdf;" + "Integrated Security=True;User Instance=True";
but it didn't work and error delare that
"Could not locate entry in sysdatabases for database 'mydatabase'. No entry found with that name. Make sure that the name is entered correctly.
BACKUP DATABASE is terminating abnormally."
and because of some reason i want to use SQLEXPRESS.
what should i do?
note:This is my sql command for backup:
backup = string.Format(@"backup database mydatabase to disk='{0}'",addr);
backup.ExecuteNonQuery();

Anyone knows how to handle (read/write) the registry to search for a path, and how to send DOS commands for example to send SQL commands to attach and dettach a database from the SQL server?

Just need to send DOS commands like "sqlcmd -S ..." to register a database in the SQL and use it in the path it puts it, I'm in the begining of my application and see the best way to use the database.

For reading the registry, Windows XP and up provide the DOS-tool REG.EXE, with which you can read AND write registry-keys.
Nah... What's up, Doc?

There are registry classes that you can use to interact with the registry. See this link.[^]
To issue DOS commands you can write a batch file on the fly and then execute it.
Here are some more relevant classes / enumerations for registry interaction

thaks it did help, just don't know how to create a batch file on the fly and execute it I'm new to C# and never used it on VB.

I suggest you get a begginners book and start from chapter one, this would fall under basic IO functions and then using the systems.diagnostics.process class to execute the batch file you created.

Hi my friends ........ I want to do term weighting by an approach called Composite measure(Tf*idf) ... it has its own formula ....
But what I want to do is to read files like(Word 2003,2007 pdf files etc.... ) then to take each word as an array .... I can read all files line by line by the following code
<br />
try<br />
{<br />
using (StreamReader sr = new StreamReader(textBox1.Text,Encoding.ASCII,true))
{<br />
String line;<br />
while ((line = sr.ReadLine()) != null)<br />
{<br />
richTextBox1.Text =richTextBox1.Text +Environment.NewLine+ line;<br />
<br />
}<br />
}<br />
}<br />
and to check the content of the file i tried to display it on a Richtextbox1 .... but it displays encrypted file .....
What I want to know is
1. How can I put each words(separated by Space and newline) in to array ... just to know each word (here displaying the content is not necessary)
2. How can I display the content of each file on Richtextbox1 ... but not in an encrypted form ....
Thanks for your help

The first thing you need to know is: Word and PDF files (as well as many others) are not necesarily line based text documents. Instead they are frequently binary files - which explains why they look encrypted.
The second thing you need to know is: Word and PDF files can be encrypted. So that may be why they lookm encrypted.
Google for "Word File Format" and "PDF File Format" - this will provide a starting point for you to gather the information you are going to need.
All those who believe in psycho kinesis, raise my hand.
