TypeScript codeplex 有一个问题描述了这一点:支持对象初始值设定项.

There is an issue on the TypeScript codeplex that describes this: Support for object initializers.

如前所述，您已经可以通过在 TypeScript 中使用接口而不是类来做到这一点:

As stated, you can already do this by using interfaces in TypeScript instead of classes:

interface Name {
    givenName: string;
    surname: string;
}
class Person {
    name: Name;
    age: number;
}

var bob: Person = {
    name: {
        givenName: "Bob",
        surname: "Smith",
    },
    age: 35,
};
