How to simplify this C# if/else syntax

I have the following statement: 

serverCard.Details = !String.IsNullOrEmpty(card.Details) ? card.Details : serverCard.Details;

I want to check and see if card.Details is null or empty... if not, write the value. Is there any syntax that allows me to leave out the else conditional?

You can write an extension method for String to check if nullOrEmpty. The regular if then would be shorter

Extension Method:

 public static bool IsNullOrEmpty(this string str)
 {
     return string.IsNullOrEmpty(str);
 }

 public static bool IsNullOrWhiteSpace(this string str)
 {
    return string.IsNullOrWhiteSpace(str);
 }

The if:

if(!card.Details.IsNullOrWhiteSpace())
    serverCard.Details = card.Details

The extension method will work for every string.

You can always use the old if statement:

if(!String.IsNullOrEmpty(card.Details))
{
  serverCard.Details = card.Details;
}

I think the ternary operator is not needed here.

Sure, just use a regular if:

if(!String.IsNullOrEmpty(card.Details))
    serverCard.Details = card.Details
