Loops are a completely different thing.
A loop enables you to do something repeatedly while a condition is true.

While loops will do the instructions inside their body while a condition is true. The condition is evaluated before the loop starts and, if it is false, the loop does not start.
<pre lang="c#">
while (condition){
//do something if condition is true
}

do{
//do something
}while(condition);

for (declaration;condition;instruction){
//do something
}

for(int i = 0;i<5;i++){
}

string[] lines = new string[10];
for(int i = 0;i<10;i++){
Console.WriteLine(lines[i]);
}

string[] lines = new string[10];
int i;
for(i = 0;i<10;i++){
Console.WriteLine(lines[i]);
}

int[] integers = new int[20];
foreach(int i in integers){
Console.WriteLine(i);
}

    }

    }

    {
        _foo.Test();
    }
    
    private void MyEventHandler(object sender, EventArgs e)
    {
