C# Basic Tutorial (Loop)

While Loop

Console.WriteLine("#####while#####");
int i = 0;
while( i < 5)
{
    Console.WriteLine(i);
    i++;
}

Console.WriteLine();
Console.WriteLine("#####do while#####");
i = 0;
do
{
    Console.WriteLine(i);
    i++;
}
while( i < 5);
Console.WriteLine();

 

For Loop

Console.WriteLine();
Console.WriteLine("#####for#####");
for (int j =0; j<5; j++)
{
    Console.WriteLine(j);
}

Console.WriteLine();
Console.WriteLine("#####foreach#####");
int[] iList = { 0, 1, 2, 3, 4 };
foreach(int item in iList)
{
    Console.WriteLine(item);
}

Break, Continue

int index = 0;
while (index < 5)
{
    Console.WriteLine(index);
    i++;
    if (i == 3)
        break;
}

index = 0;
while (index < 5)
{
    if (i == 3)
        continue;

    Console.WriteLine(index);
    i++;
}


for(int j=0; j<5; j++)
{
    if (j == 3)
        break;
    Console.WriteLine(j);
}

for (int j = 0; j < 5; j++)
{
    if (j == 3)
        continue;
    Console.WriteLine(j);
}
