Question

I think verbatim (multiline) strings in C# is a really great idea. I used to copy SQL from/to code minimizing typo errors.
Actually I need to render some javascript and I hit the wall.

The need of double quotes can be partially avoided using apostrophes in javascript, but in case you need format strings you also have to escape curly brackets:

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), this.GetType().FullName, @"
<script type=""text/javascript"">
 $(document).ready(function() {
  $('#my_button').click(function() {
   alert('Handler for .click() called.');
  });
 });
</script>
");

looks like with string.Format

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), this.GetType().FullName, string.Format(@"
<script type=""text/javascript"">
 $(document).ready(function() {{
  $('#{0}').click(function() {{
   alert('Handler for .click() called.');
  }});
 }});
</script>
"), buttonName);

I do not want to compromise speed of formating execution just to have easier life while coding using some sort of formating string preprocessing.
I hope there is some smart and easy way. Just do not want to reinvent wheel…

Thanks

I hope there is some smart and easy way.

Nope, just this incredibly slow and klunky way:

EscapeCurlies(String Input)
{
    String Temp = Input.Replace("{", "{{");
    Temp = Temp.Replace("}", "}}");

    Temp = Regex.Replace(Temp, @"{{(\d+)}}", "{$1}");

    return Temp;
}

protected void Button1_Click(object sender, EventArgs e)
{
    String buttonName = "bob";

    String FormatString = 
@"<script type=""text/javascript"">
$(document).ready(function() {
$('#{0}').click(function() {
alert('Handler for .click() called.');
});
});
</script>";

    String Test = string.Format(EscapeCurlies(FormatString), buttonName);
}
