```
I make a simple calculation with some Entry's , that works but this is not the format i really am looking for.
```

Totaaltanks.Text = total.ToString("N0", CultureInfo.InvariantCulture);

The outcome is for example 10,245,458

The format that i am looking for is that the outcome is 10245,458

With 1 comma only .

Tryed al lot of options but cannot find the one i am looking for.
