ShippingConfirmationLabel.Text = _
string.Format("Using {0} shipping to:<br>", _
ShippingTypeRadioButtonList.SelectedValue);

This however works fine:

ShippingConfirmationLabel.Text = "Using " + ShippingTypeRadioButtonList.SelectedValue + "
shipping to:<br>";

Sorry if this question has been asked earlier however upon searching nothing concrete came up for this. For some reason that code doesn't let me compile in VS.

Cheers Andrew

    @Andrew this is an error in your book; as Steve already said, there is no line continuation character; further, your second sample won't compile unless you add @ in front of the opening double quote (see link from Ria's comment) – Markus Bruckner Aug 02 '12 at 08:40
  • It is surely a typo to be corrected in your book. In C# there is no need for line continuation since a line is not considered over until you reach a semi colon (";"). – Steve Aug 02 '12 at 08:43
  • I think your book has the `_` as an indicator that the line continues to aid the reader of the printed material. It's a bit confusing though, I agree. – Dervall Aug 02 '12 at 09:04

There is no Line Continuation Character in C# like in VB.NET
In C# exist the ; to delimit the end of an instruction.
This means that there is no need for a line continuation character since a line is not considered over until you reach a semi colon (";").

The + is the string concatenation operator and it does not means Line Continuation Character

ShippingConfirmationLabel.Text = 
            "Using " + 
            ShippingTypeRadioButtonList.SelectedValue + 
            "shipping to:<br>";

As you can see, you could break the line at every point you like (of course not in the middle of a keyword or identifier) and close it with the ; terminator.

Sometimes, for legibility or other reasons, you want to break apart a single string on different lines.
In this case you could use the string concatenation operator.

C# does not have line continuations. Just use a normal line break and the code should work just fine.

C# in comparison to VB uses ; as a statement terminator, which allows you to format the code however you like without indicating that the code continues on the next line.

_ in C# is a normal character, and could be used for variable names and such.

  • You can't just use a normal line break and have the code work just fine, the compiler doesn't like it and gives the error 'new line in constant'. – chipples Nov 14 '16 at 16:47
