Hello,

I have different strings like

string s = "11.2.1";
string s1 = "53.12.1";
string s2 = "9.2.11";
string s3 = "1.12.1";


And I want Output like

s = "110201";
s1 = "531201";
s2 = "090211";
s3 = "011201";


Note: String's length is always less than 9 and there is always 2 numbers before and after .(dot).

Please provide me the best and fastest approach.

Thanks

Do you receive the strings with the dots in them? or do you need to generate them?

Yes i receive the string with the dots and i need to generate as shown in output section.

The simplest logic you can refer is as per this method i have displayed below :-

private string GetFormattedString(string strInput)
        {
            string strOutput = string.Empty;
            if (strInput.Contains("."))
            {
                string[] arrInpt = strInput.Split(new char[] { '.' });
                if(arrInpt.Length == 3){
                    if (arrInpt[0].Length == 1) strOutput = strOutput + "0" + arrInpt[0]; else strOutput = strOutput + arrInpt[0];
                    if (arrInpt[1].Length == 1) strOutput = strOutput + "0" + arrInpt[1]; else strOutput = strOutput + arrInpt[1];
                    if (arrInpt[2].Length == 1) strOutput = strOutput + "0" + arrInpt[2]; else strOutput = strOutput + arrInpt[2];
                }
            }

            return strOutput;
        }


We need to validate the string which will be passed as input to this method before passing if it is in correct format or not then it will return the desired string as output.

Hope this will be of help to you.

This is perfect. But I am looking for some optimized code. Because i need to process thousands of strings.
Hi

Check this simplest code to format the string. Hope this will help you to achieve your output.

private string FormatString(string inputString)
        {
            string formattedString = string.Empty;
            try
            {
                string[] arrInput = inputString.Split('.');
                foreach (string value in arrInput)
                {
                    if (value.Length.Equals(1))
                    { formattedString += "0" + value; }
                    else
                    { formattedString += value; }
                }
            }
            catch (Exception ex)
            { }
            return formattedString;
        }

Hi Bhushan,

what you can do on this code, rather than working for single input/output, you can pass an array or collections of input values and loop it through for input range. get the output in same length of array or collection.

This would lead an upper loop and internal loop you can take as given. "foreach" loop.

Regards

Please see this :-

private string GetFormattedString(string strInput)
        {
            return strInput.Split(new char[] { '.' })[0].PadLeft(2, '0')
                 + strInput.Split(new char[] { '.' })[1].PadLeft(2, '0')
                 + strInput.Split(new char[] { '.' })[2].PadLeft(2, '0');
        }

I think this solution is good.

Thanks
private string FormatString(string inputString)
        {
                if (inputString.Contains('.'))
{
                string formattedString = string.Empty;
                string[] arrInput = inputString.Split(".");
                foreach (string value in arrInput)
                {
                    formattedString += value.toString("00");
                }
            return formattedString;
        }
}
return inputString
)
   
v2
string s = s.Replace(".","");

Repeat same for all variables or alternatively you can create method and pass strings while calling this method.

what about the 0 append before the single digits ?
