How to Convert string("1.0000") to int

Question

The string format data with mostly 4 decimal places needs to be converted into int. I have tried this one but does not work and even directly using this Convert.ToInt16() but still did not worked:

Int32 result;
bool status = Int32.TryParse(v, out result);

Is there other ways to convert this?

Thanks.

Try using Convert.ToInt32(). – Clodhopper

Why don't you use decimal.TryParse? – Dunaway

Answer 1

You can convert it to Double first, and then convert to Int32

String s = "1.0000";
Double temp;

Boolean isOk = Double.TryParse(s, out temp);

Int32 value = isOk ? (Int32) temp : 0;

Answer 2

You can use the following:

string data = "1.0000";
int number
if(data.Contains('.'))
    number = int.Parse(data.Substring(0, data.IndexOf('.'))); //Contains decimal separator
else
    number = int.Parse(data); //Contains only numbers, no decimal separator.

Because 1.0000 has decimal places, first strip those from the string, and then parse the string to int.

Throws an exception if there is no point (or comma instead), and also interprets 10.000.000 as 10 instead of 10 million (with point as group separator) – Dunaway

@TimSchmelter the question is about a number with a point as decimal separator. This means that the culture is so that a point will not be a group separator. I agree with lack of point, will improve – Flinch

Answer 3

You have to parse it as decimal and then cast to int.

decimal resultTmp;
bool status = Decimal.TryParse("1.000".Replace(".",","), out resultTmp);
int result = (int)resultTmp;

Also change '.' to ','

why change '.' to ','? this would depend on the culture. – Seta

yes, its better to give CurrentCulture as argument. I had to change it because in mine it is not correct format. – Mcfadden
