Alright, I have an enum called Suit ...
<br />
public enum Suit<br />
{<br />
Hearts = 0,<br />
Diamonds = 1,<br />
Spades = 2,<br />
Clubs = 3,<br />
Null = -1,<br />
}<br />
And I have a function I need to create that will return the correct rank type given an integer.
I have written this function to work with a switch statement:
switch(i)
{
case 0:
return hearts;
...
}
BUT, there must be a much cleaner way to do this, by parsing the enum type from the value - I just don't know the syntax and can't seem to find it.
It must be something like:
Rank r = Enum.Parse(Rank, i);
... of course that doens't work. But it must be something similar.
Any suggestions?

Its easier than you would expect. Just convert the type:
int i = 0;
Suit suit = (Suit)i; // suit == Suit.Hearts
int index = (int)suit; // index == 0;
|
|
|
|
|
Simply casting to the enum type should work.
Rank r = (Rank)i;
Need to be careful though, this will compile and run even if the value of i is outside the range of Rank.

Thanks! Works perfect! I followed your advice and added error checking to make sure the value is between 0 and NUMRANKS (and 0 AND NUMSUITS for suits).
Thanks again!

presentation layer passes .data. to business layer.
Business layer validate the .data. if any error exist Alert message should be displayed on screen with option to continue with invalid data. And post the invalid data into a Database table with flag errorfound= .true.

DialogResult dr = MessageBox.Show("Your data has errors, Continue?","Error!",MessageBoxButtons.YesNo);
if(dr == DialogResult.Yes)
{
}

your code accessing presentation layer code
as long as architecture is concerned business layer should not call any presentation layer code.
do you have any other method

Hello,
I am trying to set up the ODBC Connection. I have the System.Data reference, and I am trying to use System.Data.Odbc directive, but there is no such option as Odbc. Any ideas why?
Thank you.

You could use the Microsoft Word ActiveX object to do this. However, all that's doing is embedding an instance of MS Word into your application. The end user would need MS Word installed before he can run your app. Is this acceptable?

What doesn't work? You *can* start a thread on the server in your button click handler, but it's not usually recommended as you have to wait for the thread to complete before sending HTML back to the client.

hi
i have a problem with programing in c#
i need to convert a string data such as ( z = x*y+2 ) to a mathematical formule
please help me to solve it 
my mail : hosseinyaghmaee@yahoo.com
thanks for your help

This is not an easy thing to do... ii was trying something similar recently...parsing a formula and tunring it into a graph (eg y=2x or y=x^2).
You have not said what you wan to do with the "formula" after it is parsed...i asuume something like fill in 2 of the 3 variables and have it calculate the third. In which case you need to solve the equation to some extent as well as parse it.
Take a look at a Design Pattern called Interpreter[^] as this is often used for writing programming or scripting languages. You want a simple scripting language with just mathematical operators.
Alternatively, somebody out there would have wriiten this already, you could search google and find something very easily.

Or use Polish notation for simpler parser. In this kind of notation, you don't need brackets:
( 3 * ( 3 + 7 ) % 2 ) / 17
standard notation
/ % * + 3 7 3 2 17
Polish notation, I think
|
|
|
|
|
Thats a good idea! Well remembered. Many of the simple parsers out there on the web use this notation as its much simpler to build the parse tree.
|
|
|
|
|
Converting from infix to reverse polish notation's a trivial task, that only involves feeding tokens to stacks.

How can this be done? I'm talking about the small icon that appears at the top-left of your windows application. If you have more .NET applications running it's annoyng 'cause they look the same in the taskbar. Thanks

I am a bad person. I thought your response both articulate and appropriate to the question, then voted you a 1 rather than 5
