String trim sample

If you need to trim string and remove extra spaces from the middle of the string
you can use this simple sample:

string s = TextBox1.Text;
s = s.Trim();                        // trim left and right spaces

while (s.IndexOf("  ") != -1)        // it is 2 spaces in the quotes!!
{
 s = s.Remove(s.IndexOf("  "), 1);   // remove extra spaces in the middle of the string
}

Label1.Text = s;

It will take any input string from the TextBox1, i.e. like this:

"___aaa_______bbb_________ccc_ddd__eee_",

where "_" is a space symbol, and trim it to the:

"aaa_bbb_ccc_ddd_eee".

All our simple samples available as Microsoft Visual Studio 2008 website projects.
