Call function in dynamic linq

Question

I\'m trying to call a function in a dynamic linq select statement, but im getting error:

No property or field \'A\' exists in type \'Tuple2\'

Answer 1

var b = new[]{ a };

The above array is don't know what type of array , and it's not type safe ?

Your values are assigned in variant data type so it's not integer value (I think string value) ,when you get this values in your query must need to convert.toint32() because your class parameter data type is integer

Please try it

 var b = new **int**[]{ a }; 

instead of var b = new[]{ a };

The important hint is here (in bold):

No property or field 'xxx' exists in **type** 'xxx'

And Please look this for previous discussion :

Dynamic Linq - no property or field exists in type 'datarow'
