Question

Can I declare / use some variable in LINQ?

For example, can I write following LINQ clearer?

var q = from PropertyDescriptor t in TypeDescriptor.GetPr         


        

Answer 1

Yes, using the let keyword:

var q = from PropertyDescriptor t in TypeDescriptor.GetProperties(instance)
    let nameProperty = t.ComponentType.GetProperty(t.Name)
    where (nameProperty != null)
    select nameProperty;
