Accessing a string by array

[Saint]

I get an error when using this code:

string str = "ahe string";
str[0]='T';

it says the indexer is read only. How can I accomplish the same thing?

Shouldnt you declare the array like pascal or so? I dont know coz i dont C# but just a curiosity!

Yeah, Strings in .NET are immutable - you can't change them without creating a new String. So, if you attempted to change one of the characters, you'll have a new string - but no reference to it.

What you want to do is declare a char array, and convert the string to a char array. Then you can change the individual characters:

string str = "ahe string";
char[] c = str.ToCharArray();
chr[0] = 't';

string newstr = new String(chr); // Convert back to string

Thanks brackett, that worked fine.
