I don't mind the occasional 'well' as I do it myself. But if you watch for it on CNN, your local news, etc. almost every reporter they cut to starts off with "Well Lou/Peter/Katie/Bill" yada yada. Once I started noticing it started to drive me crazy. That and people who do not use well/good correctly or use borrow/lend correctly.

     }

these codes look pretty but have 5 errors
1.Operator '!=' cannot be applied to operands of type 'method group' and 'int'
2.Cannot convert method group 'ReadLine' to non-delegate type 'string'. Did you intend to invoke the method?
3.'string.Trim(params char[])' is a 'method', which is not valid in the given context
4.Cannot assign to 'Trim' because it is a 'method group'
5.Cannot assign to 'Trim' because it is a 'method group'

i tried lots of times and did as i could

i hope here is someone who can solve it
thanks

The bold items are the one's I've added/changed.

string seth;
bool anm, beh, st, en;
StreamReader a = new StreamReader(".\\Format.cfg");
while (a.Peek() != -1)
{
seth = a.ReadLine();
if (seth.Trim().Length != 0)
{
if (seth.Trim() == "ABC")
{
anm = true;
}
else if (seth.Trim() == "XYZ")
{
st = true;
}
}
}

Could it be that you're usually using VB? Roll eyes | :rolleyes:

In C# you have to write '(' and ')' even for an empty method parameter list (Peek, ReadLine, Trim).
And '==' is the comparison for equality whereas '=' is reserved for assignments only.

= is the assignment operator. == is the comparison operator.

i have a new question that how can i compare bool
for instance

bool as;
if (as=true);
{
}

if i use == instead of = then its giving error

thats my question...

You compare bools by using the == operator. The = operator is the assignment operator, e.g. a = b means a gets the value of b. The == operator is the equality operator.

If you looked at my earlier answer, you would see that I amended your code to use == instead of = in all the places you had the wrong one (Unfortunately, the bold option didn't seem to show them too well).

It can be a pain getting the right search keywords. I always put C# first as it's the most relivent keyword.

This is just an example that shows you how to use FtpWebRequest class. This class does not require the use of a Web application.
