Error 1 Unable to determine the type of conditional expression

When we use ternary operators, we often encounter if? If the following two data types are inconsistent, this or that error will often be prompted.
The solution is to convert both types to object types, and then perform ternary operators

Code:

            var s = site as object;
            var n = "" as object;


data = site==null?n :s

The above site is a list collection, which perfectly solves the common problems encountered by ternary operators




Previous:Because there is no implicit conversion between <null> and System.DateTime
Next:Jquery formats /Date(1356969600000)/ into the time format of the year, month, day
