Removing curly bracket in a nested for C#

November 18, 2021

I’m trying to remove {} in a nested for but for some reason it doesn’t seem to work.

public void PrintBoard()
{
    for (int i = 0; i < _matrix.N; i++)
    {
        for (int j = 0; j < _matrix.M; j++)
        {
            Console.Write(_matrix.Get[i, j]);
        }
        Console.WriteLine();
    }
}

This is what I’m trying, but the output is kinda different, it seems that the line breaks doesn’t work properly. I also would like to know why it’s behaving like that.

public void PrintBoard()
{
    for (int i = 0; i < _matrix.N; i++)
       for (int j = 0; j < _matrix.M; j++)
           Console.Write(_matrix.Get[i, j]);
       Console.WriteLine();
}

// Output
// .........

// Output expected
// ...
// ...
// ...

>Solution :

This is because you can only remove the braces of the inner foreach, since the outer forceach has 2 statements in the block.

public void PrintBoard()
{
    for (int i = 0; i < _matrix.N; i++)
    {
        for (int j = 0; j < _matrix.M; j++)
            Console.Write(_matrix.Get[i, j]);
        Console.WriteLine();
    }
}
