Question

In SQL Server you can use the IsNull() function to check if a value is null, and if it is, return another value. Now I am wondering if there is anything similar in C#.

For example, I want to do something like:

myNewValue = IsNull(myValue, new MyValue()); 

instead of:

if (myValue == null)   myValue = new MyValue(); myNewValue = myValue; 

Thanks.

It’s called the null coalescing (??) operator:

myNewValue = myValue ?? new MyValue();
