Question

How to convert string to int?I know convert.ToInt32 is used.But it fail.Error is input string is not in proper format.
String s1 = “12.00”

Answer 1

error is because string is "12.00"

first convert string to double than in int

int a = Convert.ToInt32(Convert.ToDouble("12.00"));

or

IF you just want integer part of it than

string s= "12.00";
string[] words = s.Split('.');
int a = Convert.ToInt32(words[0]);
