I'm pretty new to programming, but I have a question:
How could I show different task output (I should use the tasks) in different lines, in the console? Also, I want to overwrite the lines each time , so the output should show:
i // overwriting this line everytime.
j // overwriting this line everytime.
I tried using SetCursorPosition, but it makes a collision between the task ouput somewhy.
A mini code sample (hope this makes it clearer):
Task a = Task.Run(() =>
{
int i;
for (i = 0; i <= 1000000; i++)
{
Console.SetCursorPosition(Console.CursorLeft, 0); // ?
Console.WriteLine("{0}", i);
}
});
Task b = Task.Run(() =>
{
int j;
for (j = 0; j <= 1000000; j++)
{
Console.SetCursorPosition(Console.CursorLeft, 3); // ?
Console.WriteLine("{0}",j);
}
});
Console.ReadLine();
Thank You in advance :)
You need to synchronize access to Console
for different tasks (I am not fixing position part if there is any problem, but an obvious synchronization problem):
var consoleLock = new object();
Task.Run(() =>
{
for (int i = 0; i <= 1000000; i++)
{
Thread.Sleep(1); // to simulate some work
lock(consoleLock)
{
Console.SetCursorPosition(Console.CursorLeft, 0);
Console.WriteLine(i);
}
}
});
Task.Run(() =>
{
for (int j = 0; j <= 1000000; j++)
{
Thread.Sleep(1); // to simulate some work
lock(consoleLock)
{
Console.SetCursorPosition(Console.CursorLeft, 3);
Console.WriteLine(j);
}
}
});
Console.ReadLine();
