How to build an expression which will produce the following statement?

```
x => x.Parameter1 == "Some text" || x.Parameter2 == "Some text" || x.Parameter3 == "Some text"
```

It’s not hard to do `x =>`

, but how to create those many OR operators?

I know we have `Expression.Or`

method, but it only accepts 2 arguments.

Thanks.

### >Solution :

So you just compile them together

psuedo code:

```
firstOr = Expression.Or(x.Parameter2 == "some test", x.Parameter3 == "sometest")
secondOr = Expression.Or(firstOr, x.Parameter1 == "Some text");
```

Then all you do is evaluate the `secondOr`

These are expression trees , and therefor you compose them together.

when you have multiple elements, segment as you would with a mathematical expression, put parenthesis around parts:

1 + 2 + 5 = 8

this is

(1 + 2) + 5 = 8

So we’ve turned 1 expression into a composition of 2 expressions.
