Convert.ToInt32("300.00") Giving error

Hi

I have a statement

Convert.ToInt32("300.00")

But it gives an error, it is obviosuly the .00 because if i remove that it works...

Is there anyway to force it to ??   The "300.00" actually comes from a string. Its a decimal number but in string format

Thanks

ianinspain,

The exact code I have is:

    int i = System.Convert.ToInt32(System.Convert.ToDouble("300.00"));

And this works.

What do you mean when you say you "tried it in a command window"? You can't just type it into the watch window of the debugger - you have to put it as a line of code in your program.

Hi ddunlea,

Yep you are right! It seems to work ... this is my actual line

if (Convert.ToInt32(Convert.ToDouble(priceFromDropDownList.SelectedValue)) != 0) // Ensure they chose something

But how do I find out what this is going to produce before i run it, I have a break point on this line so if I put my curser over priceFromDropDownList.SelectedValue   then i can see 2000000.00 ... but if i put my cursor over anything else it displays <overloaded>..

I did goto a command window while debugging, but I thought I could put

? Convert.ToInt32(Convert.ToDouble(priceFromDropDownList.SelectedValue))

but it displays 0, which isn't correct.

Sorry I come from a VB background and used to be able to do that, test variables and various things in the command window before continueing

Any ideas?

Thanks .. though it seems to have worked

ianinspain,

The easiest way is to break it up as follows:

string str = priceFromDropDownList.SelectedValue.ToString();
double d = Convert.ToDouble(str);
int i = Convert.ToInt32(d);

if(i != 0){
    ...
}

Then you can watch each intermediate variable.

ok ... thanks... wow so there isn't anyway to do what i used to do in VB

What a knockback <grin>...

It used to be great to drop to the command line window and hold your cursor over the end statement and find out exactly what it was..

What a shame

Thanks alot

Hi ianinspain,

Sometimes you can. It depends. You can examine variables and properties, but you can usually only examine simple funtion results.

Hope that helps.
