if statement in Linq query object creation-CodePudding

I am creating an object using Linq with the following code:

Model.Select(m => new { id = m.ProcessId, parent = m.ParentProcessId, text = m.Name });

However, I want to add in the following if statement for the parent property:

if (m.ParentProcessId == null)
    parent = "#";
else
    parent = m.ParentProcessId

Is there a way to do this inline with the Linq query? If not, how can this be done in a simple way?

CodePudding user response：

as in Documentation

The null-coalescing operator?? returns the value of its left-hand operand if it isn't null; otherwise, it evaluates the right-hand operand and returns its result. The ?? operator doesn't evaluate its right-hand operand if the left-hand operand evaluates to non-null.

you can try the following

Model.Select(m => new { 
       id = m.ProcessId, 
       parent = m.ParentProcessId ?? "#",
       text = m.Name });
