c# syntax for OR Clause

[LauraCairns]

Can someone please tell me what the correct syntax is for an if statement with an or clause.

Id like to be able to do the following.

if(int.Parse(No1.Text) OR int.Parse(No2.Text) OR int.Parse(No3.Text) OR int.Parse(No4.Text) OR int.Parse(No5.Text) == int.Parse(TotalPages.Text))
{
NextPage.Enabled = false;
Next5.Enabled = false;
LastPage.Enabled = false;
}

use two vertical lines as or, ie ||

Actually, in this case you only want one vertical line, see below:

if(int.Parse(No1.Text) | int.Parse(No2.Text) | int.Parse(No3.Text) | int.Parse(No4.Text) | int.Parse(No5.Text) == int.Parse(TotalPages.Text))
{
NextPage.Enabled = false;
Next5.Enabled = false;
LastPage.Enabled = false;
}

Actually, can you explain exactly what you are trying to achieve in that example?

LauraCairns -

This bit of code:

int.Parse(No1.Text)

will return an int, not a boolean. In order to cleanly use it in an "if" statement, you'll need to do a comparison of some kind, probably against 0 in this case:

(int.Parse(No1.Text) != 0)

The code has already got a comparison operator, in bold below

if(int.Parse(No1.Text) | int.Parse(No2.Text) | int.Parse(No3.Text) | int.Parse(No4.Text) | int.Parse(No5.Text) == int.Parse(TotalPages.Text))

What this code should do is check to see if the integer values in No1 - No5 are the same, and if so compare them to the integer value in TotalPages. Although I would be inclined to put brackets around the left hand side of the == to make this explicit.

Is this the behaviour you are after?

Ignore me, I am talking crap!

 

[chiph]

The full if statement (if that's what you intend) would be:

if ((int.Parse(No1.Text) != 0) || 
    (int.Parse(No2.Text) != 0) || 
    (int.Parse(No3.Text) != 0) ||
    (int.Parse(No4.Text) != 0) ||
    (int.Parse(No5.Text) == int.Parse(TotalPages.Text)))
