Converting Decimal to Double in C#?

问题

I have a variable which is storing as decimal:

decimal firststYrComp = Int16.Parse(tb1stYr.Text.ToString());

Now I have this to get typecasted into Double? How do I do that? Thanks!

回答1:

You answered your own question—Just cast it to a double:

decimal x  = 3.141592654M ;
double  pi = (double) x ;

回答2:

You can use decimal's built in converter.

decimal decimalValue = 5; 
double doubleValue = decimal.ToDouble(decimalValue);

Just Try

Decimal yourDecimal = 3.222222m;

Convert.ToDouble(yourDecimal);
