Re: How to call function after timer - C# Discussion Boards

3-Dec-20 8:07

Good evening everyone, I have a problem that crushes me. With my app developed in C #, everything works very except that I'm stuck somewhere and I try everything it does not work. Can someone show how to "call a function after the minute's number"? Using timer

Create a Timer instance, set it's Interval property to 60 * 1000 (it ticks in 1/1000th of a second intervals), and add a handler to the Tick event before you start the timer.
After one minute you will get a Tick event and your handler method will be exectuted.
A minute later the same will happen again.

Can you help me with the code ? Please

What part of it can't you do on your own?
You know how to create an instance of a Timer, I assume?

I'know how to create

Good. So do that.
And you know how to set a property of an instance, yes?

Yes

Excellent!
And you know how to add an event handler, I'm sure?

Open Visual Studio.
Immediately after you set the Interval property, type the name of your Timer instance, followed by ".Tick":

myTimer.Interval = 60 * 1000;
myTimer.Tick

Press the Tab key. Intellisense will fill in the rest of the line, and create a Tick event handler for you, containing just a "not implemented" exception for you to replace with your code.

You've done that before, haven't you? It's pretty basic stuff!

I have an array of string which is 

    string[] myarr = new[] { "a", "b", "c" };

Can you please help me how to get this result?

    a
    ab
    abc

I tried this one but I just don't know how to get the value from the array and add it on my list 

    string[] myarray = new string[] { "a", "b", "c" };
                List<string> resultarray = new List<string>();

                int i, j;
                for (i = 0; i <= myarray.Length; i++)
                {
                    for (j = i; j <= i; j++)
                    {

                        


                    }
                }

A simple loop: print the first character, print the first and the second, ...

What values do you think j is going to take within that loop?

Try debugging your code and stepping through the loops. Do the values you see in the debugger match what you were expecting?

NB: You don't need an inner loop at all. String.Join[^] has an overload which lets you specify the range of elements from the array that you want to join. For example:

string[] input = { "0", "1", "2", "3" };
string output = string.Join(string.Empty, input, 0, 3);
// Output === "012"

You get a value from an array by using an index - a numeric value that ruins from 0 to (N - 1), where N is the number of elements in the array. So valid indexes for your myarr array woudl be 0, 1, and 2.
If you want "a", then you use myarr[0]
If you want "b", then you use myarr[1]
If you want "c", then you use myarr[2]

That index value can be in a variable:

int index = 2;
Console.WriteLine(myarr[index]);

Would print "c" for example.

Think about what your tutor wants you do to, and work out how you would do it manually - that may help you work out what your code needs to do!

Give it a try - this isn't complicated!

Hint: you only need one loop!
