    Simple If Statements?

    Hello i'm trying to do simple if statements in Razor but everytime i program it in a way that you would in C#, it keeps throwing errors. How can i get something like this to work:

    @foreach (DynamicNode page in pages)
     {

           string[] tags = @page.GetPropertyValue("tags").ToString().Split(',');
           string lastItem = @tags[@tags.Length - 1];
               
            <text>Tags:
             @foreach (string tag in tags)
              {  
                    if (@tag != @lastItem)
                          <text>@tag, </text>
                    else
                         <text>@tag </text>

               }
             </text>

    }

    It does not seem to like the if statement, even if you wrap it in a tag and use @ it still doesn't seem to like the idea of comparing one string to another.

    Hi Mark

    Yup, since that's the way an if statement should look like in C# :) For others who may come across this the if statement from above should look like this

    if (@tag != @lastItem) {
         <text>@tag, </text>
} else {
         <text>@tag </text>
}

    Cheers, Jan

    Hey Jan,

    Yeah it should look like that and always best practice to use the braces in an if statement but I tend not to use them to reduce lines in my code... I guess i just thought the syntax for both Razor and C# were alike but i'm starting to find more differences as I continue to use it.

    Although in this case it will work, it's not generally a good idea to have those @ in your code block and can cause you issues.

    e.g.

    if (tag != lastItem) {
    <text>@tag, </text>
} else {
    <text>@tag </text>
}
