Hi,

I need to format a string.

Source string: 123332qw332w2

Result string: 123-332-qw3-32w2

Is there any easy way to do it as we do for numbers(String.Format)?

Format is not fixed. It is given in the config file like xxx-xxxxx-xxxxx.

That can be stored in some format like xxx-xxxxx-xxx. A group of values take a single format like above.. I need the formatting should be based on a given format like above. Format xxx-xxxxx-xxx will be made configurable. Hope this explains

Solution 2

try this

C#

public void stringFormat()
       {
           var str = "123332qw332w2";
           var newStr = "";
           var increment = 1;
           for (int index = 3; index < 15; index += (3 + increment))
           {
               newStr = str.Insert(index, "-");
               str = newStr;

           }
             newStr;//final output
       }

It will show your desired output
Happy coding :)

Some times the format may be different. so i thought to have a generic solution
12-222525-251 or 1245-564-2541

So the format is not fixed right?

That can be stored in some format like xxx-xxxxx-xxx. A group of values take a single format like above.. I need the formatting should be based on a given format like above. Format xxx-xxxxx-xxx will be made configurable. Hope this explains
