well, we can't help you with that.
how should we know where to place the commas. you provided no reasonable infos for that.

string[] words = string.Split(',');

foreach (string word in words)

It's not working for dynamic strings
1. You can split (separate) a string into sub-strings when you now the separators chars (spaces, coma, etc), and in that case you should use the string.Split() method like is indicated in "Solution 1" above.

2.But in your case you have a set of concatenated words with no separators between them.
In this case you should provide some rule that could be used for splitting, like in your case all words from the string has the same length (8 chars). So if you have this rule the the solution is the next one:
string input = "usernameemail_idpassword";
int length = 8;
int n = input.Length;
StringBuilder temp = new StringBuilder();
for(int i=0; i< n; i+=length)
    if (i > 0)
        //Add the separator.
    //Split the string using the "fixed length" rule.
    temp.Append(input.Substring(i, length));
// Get the result.
string result = temp.ToString();

not acceptable

Reason it wont work is there isnt any fixed delimiter from which one could get the position and get the outputs separately. This is why Raul has specified a business rule where in a fixed length can be used. Since "usrnmemail_idpwd" and "usernameemail_idpassword" cannot be split using the same business rule or logic.

Thank you for your support comment!

There is no solution in your case if you don't have a rule, like "length rule" (from my solution) or something similar.
