Say I have a string abcdefghi
I would like to extract from that the string cdef
I know that the index of the last character I want is 5 (which is f).
I also know that I want to take the 3 preceding characters with it.
Here is my code so far, which does work, but doesn't look that pretty. Is there a better way?
string text = "abcdefghi";
int lastIndex = 5;
int numberOfCharsToTake = 4 // including the last index char
Console.WriteLine(
string.Join("",
text
.Substring(0, lastIndex + 1)
.Reverse()
.Take(numberOfCharsToTake)
.Reverse()
)
)
string text = "abcdefghi";
string lastIndex = 5;
string numberOfCharsToTake = 4 // including the last index char
Console.WriteLine(
text.Substring(lastIndex - numberOfCharsToTake, numberOfCharsToTake)
);
