C# - converting string with decimals to integer

Question

I have a string "1.0.0.1";

I want to convert this string to numeric values = 1001;

how do i do this?

Answer 1

The easiest way would be to strip out the periods and parse:

var input = "1.0.0.1";
int number = int.Parse(input.Replace(".", ""));

Note - this version will throw an exception if the string is not a number once the periods are stripped out. If you don't want this behaviour, you can use int.TryParse

var input = "1.0.0.1";
int number;

int.TryParse(input.Replace(".", ""), out number);

Answer 2

你可以试试

int.Parse(myString.Replace(".", ""))

Answer 3

    Int32 num;
    String numString = "1.0.0.1";

    Boolean success = Int32.TryParse(numString.Replace(".",""), out num);

Then you can test that success is true before attempting to use the num integer.

Answer 4

        string number = "1.0.1.0.1";
        var convertedString = int.Parse(number.Replace(".",""));

This should work.

Answer 5

if your string is static

 int number = Convert.ToInt32("1.0.0.1".Replace(".", ""));

else

int number = Convert.ToInt32(yourstringvariable.Replace(".", ""));
