String.IsNullOrWhiteSpace in LINQ Expression

Question

I have the following code:

return this.ObjectContext.BranchCostDetails.Where(
    b => b.TarrifId == tariffId && b.Diameter == diameter
        ||         


        

Answer 1

You can also use this to check for whitespace:

b.Diameter!=null && !String.IsNullOrEmpty(b.Diameter.Trim())
