TypeScript数据类型转换

Question

I am new in TypeScript/Angular JS 2. I have one function written in C# that I need to convert in TypeScript. Below is the function-

public static MyModel GetDetails(IDictionary<string, object> Obj) {

  MyModel dlModel = new MyModel();
  if (Obj.ContainsKey("action"))

    dlModel.action = ((IEnumerable<object>)Obj["action"]).Cast<string>().ToList();
  if (Obj.ContainsKey("parameters")) {

    List<object> pr = ((IEnumerable<object>)Obj["parameters"]).Cast<object>().ToList();
    foreach (object obj in pr) {
      IDictionary<string, object> kValue = (IDictionary<string, object>)obj;

      dlModel.parameters.Add(new KeyValuePair<string, string>(kValue["Key"].ToString(), kValue["Value"].ToString()));


    }
}

But I am not sure how to use IDictionary and IEnumerable in TypeScript. So can anyone help me out in TypeScript data types.

Answer 1

So can anyone help me out in TypeScript data types.

Best to use {[key: string]: SomeObject} where SomeObject is the value for a given string key .
