C# Input string was not in a correct format? [duplicate]

Question

What is wrong with my code? Here is my code:

public override string ToString()
{
    return String.Format("Number : {0} \nFloors:{1} \nStreet \n{ \nName : {2},\nLength : {3}\n}",Number,Floors,Street.Name,Street.Length);
}

Answer 1

You need to escape your curly brackets:

"Number : {0} \nFloors:{1} \nStreet \n{{ \nName : {2},\nLength : {3}\n}}"

If you need { or } in the resulting string, you need to escape them as {{ and }}.
