Insert only adds. Replace changes.

Edit . As others have pointed out, strings are valid immutable, so both methods will return a copy of the original string. However, the semantics of the operations are the same as above.

Not. Strings are immutable. string.Insert returns a new string with the inserted value. It doesn't change the old line.

string newString = oldString.Insert(3, "foo);

oldString does not change. But "foo" is now in newString.

Strings in C # are immutable. They cannot be changed except by reflection or unsafe code (and you should never do that).

All methods on the line that "change" instead return a new line with the appropriate changes.

Since insertion puts one string on top of another, the result of inserting a string s1

into a string s2

will contain the string length s1.Lnegth + s2.Length

, no characters will be lost.
