Let say I have a string "ABCDEFGH"and I would like to add a char into this string such as (adding Z to the fourth column);
ABCZDEFGH
How can I do this efficiently instead of changing string into char, moving all chars to the new column, and adding the char later?
You can use the string.Insert method.
string test = "ABCDEFGH";
test = test.Insert(3, "Z");
Have a look at the docs for more information.
You could try:
string str = "ABCDEFGH";
str = str.Insert(3, "Z");
Why not just Insert:
string source = "ABCDEFGH";
char item = 'Z';
string result = source.Insert(3, item.ToString());
Use string.Insert:
var start = "ABCDEFGH";
var result = start.Insert(3, "Z");
Note that indexes are 0 based.
if you don't know the index you can do it like this
result = test.Insert(test.IndexOf("C"), "Z");
