如何在Angular 4中创建模式类型？

Question

How to create model type for the below value (interface) in angular 4,

          [{ "id": "CC", "value": "Connect Orlando" },
           {"id": "CB", "value": "Connect Bengaluru"},
           {"id": "CS", "value": "Connect Mumbai" }]

i tried something like below

export class DropdownModel {
    public options: DropdownOptionsModel[];
}

export class DropdownOptionsModel {
    public id: any;
    public value: any;
}

but getting error "property option is missing" in the below line

this.mergedList= <DropdownModel> this.mergeValue(this.serviceCall.list1 ,this.serviceCall.list2 );

 private mergeValue(list1, list2) {
        let merged = [];
        for (let list of list1) {
            merged.push(list);
        }
        for (let list of list2) {
            merged.push(list);
        }
        return merged;
    }

i was trying to merge two arrays and storing it inside mergedList variable.

It should simply be this

export class DropdownOptionsModel {
    public id: any;
    public value: any;
}

Your result is an array of DropdownOptionsModel => DropdownOptionsModel[]

What you're saying here is:

export class DropdownModel {
    public options: DropdownOptionsModel[];
}

I have an object that has an options property that stores an array of { id, value }
