I have a string line = " DOL : 12/04/09 "

I want to remove the white spaces and to get the string like
line = "DOL : 12/04/09" ;

i have th e following coding but it is not going to if statement.

line.Trim();
if (line.StartsWith("DOL"))
{
start++;
}

String is immutable; use:

line = line.Trim();

seema,

Calling methods that perform adjustments on the string actually return a
new instance of a string with the adjustments applied. In this case, you
have to do this:

line = line.Trim();

if (line.StartsWith("DOL"))
....

string line = " DOL : 12/04/09 ";
string x = line.Trim();

if(x.StartsWith("DOL"))
{
//do something
}

Trim returns a new string, so you need to do

line = line.Trim();

Strings in C# are immutable and cannot be changed.

without a new string variable or reassigning the value of line

if(line.Trim().StartsWith("DOL"))
{
//do something
}
