无法将类型“Java.Lang.Object"隐式转换为“Android.Runtime.JavaDictionary<string, string>" [英] Cannot implicitly convert type &#39;Java.Lang.Object&#39; to &#39;Android.Runtime.JavaDictionary&lt;string, string&gt;

问题描述

我正在我的应用程序上应用 Google Places Api 并将 Java 转换为 C# 代码.但是当我在列表中获取附近的地点时，我收到了这个错误:

I am applying Google Places Api on my app and converting the Java to C# code. But when I am getting the nearby places in the list, I got this error:

无法将类型Java.Lang.Object"隐式转换为Android.Runtime.JavaDictionary".存在显式转换(您是否缺少强制转换?)

Cannot implicitly convert type 'Java.Lang.Object' to 'Android.Runtime.JavaDictionary'. An explicit conversion exists (are you missing a cast?)

private void showNearbyPlaces(JavaList<JavaDictionary<string, string>> placeList)
    {
        for (int eachPlace = 0; eachPlace < placeList.Size(); eachPlace++)
        {

            MarkerOptions markerOptions = new MarkerOptions();
            JavaDictionary<string, string> googlePlace = placeList.Get(eachPlace); /*This is the error*/
        }
    }

知道如何解决这个问题吗?谢谢你.

Any know how to fix this? Thank you.

推荐答案

您可以使用 System.Collections.Generic.List 而不是 JavaList，例如:

You could use System.Collections.Generic.List instead of JavaList, for example :

using System.Linq;

...

private void showNearbyPlaces(List<JavaDictionary<string, string>> placeList)
{
    for (int eachPlace = 0; eachPlace < placeList.Count; eachPlace++)
    {
        JavaDictionary<string, string> googlePlace = placeList.ElementAt(eachPlace);
    }
}
