Count String Relpacements using Replace Function

[kermit888]

Hi, I successfully use the string.replace function. Newstring = oldstring.replace(“*”,”~”) Now I want to count the number of replacements made. Thanks in advance! Kermit

Hi, String.Replace() or any other method wont tell you, but you could try a loop

int startPosition=0;
int n;
for (n=0; ;n++) {
startPosition=oldstring.IndexOf(searchString, startPosition)+1;
if (startPosition<=0) break;
}

before performing the Replace. :)

Perhaps it can be done using a RegEx replace and a delegate. That would give you the opportunity to do something for each replacement. A simple way (but not so effective if the string is large) is to create a string where you remove the character, and compare the lengths: int cnt = oldstring.Length - oldstring.Replace("*", "").Length;

before doing the replacement you could use RegEx.Matches(InputString,SearchPattern).Count. BTW: RegEx.Replace is also a good method to do string-replacements. - walter
