My own version of replace

[implement]

Hi all!

I try to code my own version of replace but it doesn't work. I hope
somebody can help me out.
It only replaces the first char!.

Why I don't use the public string.replace function? Well I love
implementing string functions :-).

I coded another function for replacing chars in a word and this
function works!

Thank you for any help

Use:

string text = "Good Morning";
replaceStr(text ,"Morning","Eve ning");
Console.WriteLi ne(text);

Output: Good Eorning // Only the first char

Here is the function

public static void replaceStr(stri ng word, string word2, string
replace)
{
int i;
int x = 0, y, z = 0, l = 0;
char[] place = new char[word.Length];
for (i = 0; i < word.Length; i++)
{
place[x] = word[i]; // fills the place Array
x++;
}

for (y = 0; y < place.Length; y++)
{

if (place[y] == word2[z]) /
{

place[y] = replace[l]; // It only replaces the
first char
l++;
y++;
z++;

}
}

Console.WriteLi ne(place);

}

It appears you have changed the code since your original post. Can you
supply your current code as well as the inputs that you are passing into
your replaceStr method?

The standard replace function is nice but I want to look behind the
screen how these things are implemented. I tried Reflector but it
doesn't show me the whole implementations . So I try to build these
functions again. Just for fun :-)

If it is the implementation that you are interested in, the following
downloads might be of value:

I mean it's always easier replacing single chars than grouped
chars(strings)

Maybe so, but that isn't what string.Replace does so if you are trying
to reproduce the behavior of that you'll need to find the match across
the group and replace the group, taking into account that the number of
elements in the replacement group might be more or less than the number
of elements they are replacing. string.Replace also supports passing
null or an empty string as the "replace with" value, with the result
being that matched items are removed from the original string.
