I initialize a variable g consisting of only digits not exceeding 2, then I initialize a bool array consisting of three elements and at f[g[0]] I get an exception, “The index was outside the bounds of the array.” since f[3] why g[0] = f.length always regardless of the length of g and the value of g[0] ?

string g = “022”;

bool[] f = { true, true, true };

Console.WriteLine(f[(int)g[0]]);
Console.ReadLine();
