what is it doing? is it running?

not a c# head but this is fairly simple.

in pseudocode

begin
    str := "some sort of sentence."

    for i in str.length
        if str[i] == " "
        then
        str[i] = "_"
    
    print str
end

also wrap code in [.code][./code] - minus the dots - to improve readability.

There's a function in class String called Replace that will do this for you.

Strings are immutable. you need to call it like:

string str2 = str1.Remove(0, 5);
