  @}  else {ViewBag.name }

but I get error! would you please help me

Answer 1

@ is used to start writing razor statements i.e. C# code and within html we can still use razor statements starting with @

The following is the correct syntax for it:

@if (ViewBag.name == null)
{
   <h3> name is empty.... </h3>
}
else 
{
    <h3>@ViewBag.name</h3>
}

it can be more simplified like below:

 <h3> @(ViewBag.name == null ? "name is empty...." : ViewBag.name) </h3>
