Hello Guys ! I am strting to learn a C# languge and i dont know ...

[thekm1994]

I am Starting to learn C# and i dont know how to get a value for a variable while the program is runing , Lets say ' it should be like a progrram that you run it ' (output) "Put in a number" (input) value for the varable (output) "You choosed number {varible value}" ! Thanks /yea/me

Console? Use the Console. Object...

Console.ReadLine()

[thekm1994]

Yes . I know that , Console.ReadLine(); , But how can i use it for reading a value into a variable ? should it be like C++ ?

[php]
static void Main(string[] args)
{
int variable_value;


Console.WriteLine("Put in a number");
variable_value = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("You choosed number {0}", variable_value);

Console.WriteLine("\n" + "Press any key to exit.");
Console.ReadKey();
}
[/php]

It should be obvious btw Kuro is using Convert.ToInt32 because ReadLine returns a String, and you obviously can't get a string on a int var.

If you are saving on a string, you won't need any convert.

[Kuro Tenshi]

ehm try it, i know its not 100% correct but it started whining when i implemented tostring @ variable_value and yeah this works.

man all i said was that you were right and explained the OP why you used convert... what's wrong with you? oO

[Kuro Tenshi]

Everything

but yeah i added a fail safe just incase, but yeah i think im overrushing him with these codes no?

[php]
static void Main(string[] args)
{
main:
int variable_value;


Console.WriteLine("Put in a number");
try
{
variable_value = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("You choosed number {0}", variable_value);
Console.WriteLine("\n" + "Press any key to exit.");
Console.ReadKey();
}
catch
{
Console.WriteLine("Wrong input!");
Console.WriteLine("\n" + "Press any key to retry.");
Console.ReadKey();
Console.Clear();
goto main;
}
}
[/php]

i could have used an int main but its to anoying to add an return command @ try
at least its shorter then a while loop and then all those if fuctions...

[thekm1994]

Wow that is a tuff thing !!! Any way thanks you all for helping me out :P

[Kuro Tenshi]

here you want so something tuff, im learning webparts now this is how far i progressed in 1.5 weeks:

i was stuck at the ip checker but this pc had IPV6 also enabled now all i need to do is fix the counter(halfway there) and add a sharepoint modifier for the admins of the site to set the settings for the viewers.

this is a simple program =-= god cant wait for the next prject the original thing i had to make i already had done for a week/half a week. but i need to add protection with ip and refresh and such so it takes a while to do.
