C# Casting to a decimal

Question

What, if any, is the difference between?

decimal d = (decimal) myDouble;
decimal d = new decimal(myDouble);
decimal d = Convert.ToDecimal(myDouble);

Answer 1

There is no difference. If you look at the source:

In Decimal:

public static explicit operator decimal(double value)
{
    return new decimal(value);
}    

In Convert:

public static decimal ToDecimal(float value)
{
    return (decimal) value;
}

So in the end they all call new decimal(double).
