you are missing a critical piece... you have to store the data somewhere...


string test=@"test";
string test2=@"xxxxx";
test = test.Insert(1,test2);

test.Insert(1,test2) is a function call that returns a string....

in your code above you don't do anything with that string that gets returned

I  assign it back to 'test'. So when I look at 'test', it should be "texxxxst"?
