Question

I have this

this GetInformation is my Entity.Getinformation class.. when I am trying to assign result globly I am getting Cannot Assign to implicit typed local variable?

var result = ?

what should I assign in global?

Answer 1

It sounds like you're trying to do var result = null; which won't work because null doesn't tell the compiler what type result should be. You would need to use Sometype result = null;.

Answer 2

When you say "assign result globally", do you mean using it as a class variable?

class SomeClass {
    var result = general.GetInformation(int.Parse(ID), F_account, F_Info, Types);
}

In that case, you can't use var and you would have to use whatever Type GetInformation returns, for example

string result =  general.GetInformation(int.Parse(ID), F_account, F_Info, Types);

or

Entity result =  general.GetInformation(int.Parse(ID), F_account, F_Info, Types);
