对象文字的旋转属性

Question

TypeScript是否有办法将对象文字的属性分配给某个类型？

考虑以下示例：

interface ILiteralType
{
    // I don't know what is going to be part of this object
    // but I know it should be of type string.
    *: string;
}

class MyClass
{
    properties: ILiteralType;
}

var m = new MyClass();
m.properties = {
    name: "A name",           // ok
    age: 10,                  // error: Should be a string
    anotherProp: "some value" // ok too
    ...
};

我认为你正在寻找这个：

interface ILiteralType
{
    [property: string]: string;
}

这将要求所有属性值都是字符串。
