If I have two strings .. say
string1="Hello Dear c'Lint"
and
string2="Dear"
.. I want to Compare the strings first and delete the matching substring ..
the result of the above string pairs is:
"Hello c'Lint"
(i.e, two spaces between "Hello" and "c'Lint")
for simplicity, we'll assume that string2 will be the sub-set of string1 .. (i mean string1 will contain string2)..
What about
string result = string1.Replace(string2,"");
EDIT: I saw your updated question too late :)
An alternative solution to replace only the first occurrence using Regex.Replace, just for curiosity:
string s1 = "Hello dear Alice and dear Bob.";
string s2 = "dear";
bool first = true;
string s3 = Regex.Replace(s1, s2, (m) => {
if (first) {
first = false;
return "";
}
return s2;
});
