Known string "adcdefg" how to use c # timer every 1 s output characters?-CodePudding

1 s output a, for example, output b 2 seconds, 3 seconds output c

 [TestMethod]Public void TimerTest ()

String woutStr="abcdefg"; 
int index=0; 
The Timer Timer=new Timer (new TimerCallback (obj=& gt; 
{
The Debug. WriteLine (woutStr [index % woutStr Length]); 
Index++; 
}), null, 0, 1000); 
The timer. Change (0, 1000); 
//wait for output 
Thread.sleep (1000 * 10);

Use nuget introduce rx.net

The

reference

Install - Package System. Reactive

The

reference

string x="abcdefghijk";
Var ob1=x.T oObservable ();
Observables. Interval (TimeSpan. FromSeconds (1))
.zip (ob1, (a, b)=& gt; B)
The Subscribe (p=& gt; {the Console. WriteLine (p); });

Just want to say Rx found that has already been answered

CodePudding user response:

This also line

 string STR="abcdefghijk"; 
Var observables=
Observables. Generate (x=0, & gt; X & lt; STR. Length, x=& gt; X + 1, x=& gt; X, 
X=& gt; TimeSpan. FromSeconds (1)). Timestamp (); 

Observables. Subscribe (p=& gt; Console. WriteLine (${" STR [p.V alue]}, {p.T imestamp} "));

CodePudding user response:

So still can

 observables. Generate (" abcdefghijk ". GetEnumerator (), 
Events=& gt; Events. MoveNext (), 
Events=& gt; Events, 
Events=& gt; Events. The Current, 
X=& gt; TimeSpan. FromSeconds (1)) 
The Timestamp () 
The Subscribe (p=& gt; 
{
Console. WriteLine (${" p.V alue}, {p.T imestamp} "); 

});

Is operating in the winform, first seconds display a, more than 2 seconds shows a b, the output is ab, more than 3 seconds according to c, output is ABC, until the final string all displayed

CodePudding user response:

 char c='a'; 
New Timer ((x)=& gt; 
{
Console. WriteLine (c + +); 
}). Change (0, 1000);

CodePudding user response:

Can be achieved, thank you very much

CodePudding user response:

Cout<

[a * 2], Sleep (444), was originally thought it was a c + + c #?

CodePudding user response:

Is not the most simple should use a timer?

CodePudding user response:

Use the timer,,,

CodePudding user response:

Is a dynamic effect, word by word to do animation timing without too accurate delay line

CodePudding user response:

After each output, sleep (1000)

CodePudding user response:

After all the.net asynchronous programming specification has been out for many years, many programming languages are basically uniform, this should be common sense to learn, as a result, the most relevant timer, events, and so on mechanism could be abandoned ,

 using System; 
Using System. The Threading. The Tasks; 

The namespace ConsoleApp1 
{
Class Program 
{
The static void Main (string [] args) 
{
The Test (); 
Console. WriteLine ("... Press any key to end "); 
The Console. ReadKey (); 
} 

Private static async void Test () 
{
Foreach (var c in string \ "known" adcdefg \ "how to use c # timer every 1 s output character?" ) 
{
The Console. Write (c); 
Await Task. Delay (500); 
} 
} 
} 
}

For winform, just that one line of code to control the output characters. The BeginInvoke entrusted to operate controls, other asynchronous programming logic is the same,

CodePudding user response:

You can write in the winform
