The Solution 1 and 2 are correct. In most cases, you don't need to output value in its default format.
First of all, you assign a double value to a string property. Such assignment makes no sense in .NET, but VB.NET provides "automatic" work-around by assigning not double value, but
double.ToString(), which is actually a bad thing; it would be much better it if issued a compilation error instead, as it is normally done.
You should always use
ToString, which also allows you, in other forms of this function, to provide culture, format string, of both. Please see:
