How do I get the value from the select option in Angular 4?

I want to assign it to a new variable in the component.ts file. I've tried this but outputs nothing.

Can you also do it using [(ngModel)]?

component.html

```
<form class="form-inline" (ngSubmit)="HelloCorp(f)" #f="ngForm">
     <div class="select">
         <select class="form-control col-lg-8" #corporation required>
             <option *ngFor="let corporation of corporations" [value]="corporationObj">{{corporation.corp_name}}</option>    
         </select>
             <button type="submit" class="btn btn-primary manage">Submit</button>
     </div>
</form>

```

component.ts

```
HelloCorp() {
const corporationObj = corporation.value;
}

```
