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(). – R.Rusev Sep 02 '16 at 08:32 — R.Rusev, Sep 02 '16 at 08:32
Why don't you use `decimal.TryParse`? – Tim Schmelter Sep 02 '16 at 08:36 — Tim Schmelter, Sep 02 '16 at 08:36

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;

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) – Tim Schmelter Sep 02 '16 at 08:38
@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 – SynerCoder Sep 02 '16 at 08:57

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. – harryovers Sep 02 '16 at 08:40
yes, its better to give CurrentCulture as argument. I had to change it because in mine it is not correct format. – apukineimakiapudjuh Sep 02 '16 at 10:16
