String.Insert Doesn't work...

[Steph.]

Hi,

String.Insert doesn't seems to work.... (see example below)
Could someone explain me this ? :
private void button1_Click(o bject sender, System.EventArg s e)
{
string tmp="1234567890 1234567890";
string toinsert="HELLO ";
tmp.Insert(10,t oinsert);
MessageBox.Show (tmp);
}

And the message box show : 123456789012345 67890 instead of 1234567890HELLO 1234567890

Thanks for Help,

steph.

Steph,

The Insert method does not change the string it is called on. Strings
are immutable. Rather, it returns a new string that has the inserted text.
All methods that perform operations on strings work in this manner.

Hope this helps.

Hi,

Try this:
string tmp = "12345678901234 567890";
string toInsert = "HELLO";
tmp = tmp.Insert (10, toInsert);
