Question

The scenario is I would like to write a hidden field with a guid value generated by the server.

Why does

<input type="hidden" id="sampleGuid" value="@{Guid.NewGuid().ToString()};" />

yield ‘value=””‘ while

@{
     string token = Guid.NewGuid().ToString();
    <input type="hidden" id="sampleGuid" value="@token" />
     }

properly fill in ‘value’ with a guid?

Answer 1

You need parentheses instead of braces.

@{ ... } will execute ordinary statements, but won’t print anything.

@(...) will print the value of an expression. (and will HTML-encode it)
