I am new to C#. My problem is to take odd chars from a string
and get a new string
from those odds.
string name = "Filip"; // expected output ="Flp"
I don't want to take, for example,
string result = name.Substring(0, 1) + name.Substring(2, 1) + ... etc.
I need a function for this operation.
Try Linq (you actually want even characters since string
is zero-based ):
string name = "Filip";
string result = string.Concat(name.Where((c, i) => i % 2 == 0));
In case of good old loop implementation, I suggest building the string
with a help of StringBuilder
:
StringBuilder sb = new StringBuilder(name.Length / 2 + 1);
for (int i = 0; i < name.Length; i += 2)
sb.Append(name[i]);
string result = sb.ToString();
