How do I check for null/empty value in cshtml

<b>Start Date: </b>@employee["StartDate"].<br />

Using MVC Razor 3/C#, how can I check if employee["StartDate"] value is null/empty in the cshtml? So that if it is, I instead display:

<b>Start Date: </b>Unknown.<br />

I tried: 

@if(employee["StartDate"] == null){<b>Start Date: </b>Unknown.<br />}

but that doesn't work.

Have tried like below, I have tired similar null check, it should work

@if(employee["StartDate"] != DateTime.MinValue){
  <Start Date: </b>@employee["StartDate"].<br />
}
else{
  <b>Start Date: </b>Unknown.<br />
}

I ended up using this:

@if(employee["StartDate"].ToString() == ""){<b>Start Date: </b>Unknown.<br />}
else{<Start Date: </b>@employee["StartDate"].<br />}

But is there a "cleaner" way to write this?

If you are only worried about null or empty

@(String.IsNullOrEmpty(employee["StartDate"])?"Unknow":employee["StartDate"])

If startDate is a DateTime try to compare it with DateTime.MinValue.

If you have more problems you can put breakpoint in razor code to see what exactly is that field

Try 

<b>Start Date: </b>@(employee["StartDate"] ?? "Unknown").<br />

?? return the left-side value, or the right-side value if the left-side value is null.
