Try:

string mystring = "1234,34,26,6,1,0";
string[] numbersAsStrings = mystring.Split(',');
int[] numberAsInts = new int[numbersAsStrings.Length];
for (int index = 0; index < numbersAsStrings.Length; index++)
{
    numberAsInts[index] = int.Parse(numbersAsStrings[index]);
}

Would not expect too much in the way of performance though - there are two expensive operations there, the Split and the Parse.

Mark,

Your a star - cheers!

That does the job perfectly.
This is one big learning curve!

Thanks again for your help.

Regards Gordon.

I want to take a string that has a series on numbers separated by commas, like: string mystring = "1234,34,26,6,1,0"; and extract those numbers into a number of integers, like: int a, int b, int c, int d, int e, int f ....etc. or into an array -> int[1 to x] numbers; Can any one give an example of possible code? Regards Gordon

Gordon,

Does the following achieve what you are trying to do?

string[] portNames = { "PortA", "PortB", "PortC" };
Hashtable ports;

ports = new Hashtable();
ports.Add(portNames[0], new InputPort(Pins.GPIO_PIN_D0, true, Port.ResistorMode.Disabled));
ports.Add(portNames[2], new InputPort(Pins.GPIO_PIN_D1, true, Port.ResistorMode.Disabled));
ports.Add(portNames[1], new InputPort(Pins.GPIO_PIN_D2, true, Port.ResistorMode.Disabled));
for (int index = 0; index < portNames.Length; index++)
{
    Debug.Print("Port '" + portNames[index] + "' - " + ((InputPort) ports[portNames[index]]).Read());
}

Note:
- I mixed up the assignment to illustrate that the Hashtable does not need things added in the same order as they are addressed. Hence PortC is GPIO_D1.
- This code has not been tested on hardware.

You can find more examples using Hashtables here.

Mark,

Thanks, will check your code out and have a look at the link you included.

Regards Gordon

I think a HashTable may help you.

Nevyn,

Mark, I've had a look at the link above, as I am new to C# and .NET Microframework, I don't understand how I can use a HashTable. Maybe you could give me pointer with a sample code.

I wanted to store the names of the ports in a variable array and then use the array to address the ports from a loop.

so something like, say the port names are "port_a", "port_b", "port_c"........
stored in some kind of array so that, array_variable[0] equals "port_a", array_variable[1] equals "port_b"...etc

Then us something like: (portstatus being a bool)

"portstatus = array_variable[i].read();"

so assuming i = 1,

then the line would be interpreted to be: "portstatus = port_b.read();"

Is this possible or am I barking up the wrong tree!!

Regards Gordon (newby)

ItsDan,

I ment to put:

Debug.Print(portnameStr[i].read().ToString());

Gordon

That will work fine but if you're saying you made led1 and are trying to do led[i] where i=1, no that won't work.

OutputPort leds[8];
bool portstatus[8];

The above would create arrays that can be looped.

ItsDan,

Thanks for the reply. I have probably confused the issue by putting led0 etc.
led0 is the name of the output port:

private static OutputPort _led0 = new OutputPort(Pins.GPIO_PIN_D0, false);
private static OutputPort _led1 = new OutputPort(Pins.GPIO_PIN_D1, false);

I want to be able to asign he name of the port to an array:

string[] portnameStr = "led0", "led1", etc......


for ( int i, i <= 5, i++)
{
Debug.Print(portnameStr[i].read().ToString());
}


This is something like I'm trying to achieve, to address the ports using a string variable.
Is it possible and if so, what is the correct code.


Regards Gordon

Hello fellow N+'s

I'm new to this stuff, but my first home automation is on it's way.
I have programmed some time ago in C++, but not to good with C# and Micro Framework.

I have been trying to address digital I/O ports with variables e.g.

// Read status of all Ports.
using a "for i loop"
portstatus[i] = portname[i].Read();

The above line doesn't work so I've had to type every port on a separate line:

portstatus[0] = led0.Read();
portstatus[1] = led1.Read();
portstatus[2] = led2.Read();

etc.

Can any body help on this matter?

Regards Gordon

It could be that rawData length is less then 5, you can try replacing:
string commandData = rawData.Substring(5, rawData.Length – 5);
with:
string commandData = (rawData.Lenght >= 5) rawData.Substring(5, rawData.Length – 5) ? "";

However, the real issue is why is the rawData length is less than 5?

Veetrik,

Thanks for your reply. I tried what you suggested, but the assembler didn't like the code.
After some investigation I found my problem in the program.cs.
There was no trap for a bad command sent from the browser.

Thanks again Gordon

Hello fellow N+'s Code taken from: http://www.schuurmans.cc/tag/webserver I’ve use the code to do with this article and it does the job I’m looking for. How ever, I send a request to the server and all works OK. When I go to send another request a little later, it is as though the server has frozen.
