索引（从零开始）必须大于或等于零单位

Question

我需要这方面的帮助。它在我的 logcat 上说：

System.FormatException：索引（从零开始）必须大于或等于零且小于参数列表的大小。

这是我到目前为止所做的。

1.) string full_path = string.Format("{0} {1}",Application.streamingAssetsPath + path_with_extention_under_streaming_assets_folder);

2.) string full_path = string.Format("{0}/{1}",Application.streamingAssetsPath + path_with_extention_under_streaming_assets_folder);

3.) string full_path = string.Format("{0}",Application.streamingAssetsPath + path_with_extention_under_streaming_assets_folder);

所有这些都不起作用。我的 logcat 上仍然出现错误

这是我的实际代码：

// Load 2 (StreamingAssets).
public static string LoadJsonFromStreamingAssets(string path_with_extention_under_streaming_assets_folder)
{
    string json = null;
    try
    {
        //Android Platform
    #if UNITY_ANDROID

        string full_path = string.Format("{0}/{1}",Application.streamingAssetsPath + path_with_extention_under_streaming_assets_folder);

        // Android only use WWW to read file
        WWW reader = new WWW(full_path);
        while (!reader.isDone){}

        json = reader.text;

        // PK Debug 2017.12.11
        Debug.Log("STEP 1. ");
        Debug.Log(json);

        JsonData itemData = JsonMapper.ToObject(json);

        Debug.Log("STEP 2. ");

     #else
        string full_path = string.Format("{0}/{1}", Application.streamingAssetsPath, path_with_extention_under_streaming_assets_folder);
        StreamReader reader = new StreamReader(full_path);
        json = reader.ReadToEnd().Trim();
        reader.Close();
     #endif
    }
    catch (Exception e)
    {
        Debug.LogWarningFormat("Failed to Load.\n{0}\n{1}", e, path_with_extention_under_streaming_assets_folder);
    }
    return json;
}

我通过更改找到了解决方案：

string full_path = string.Format("{0}/{1}",Application.streamingAssetsPath + path_with_extention_under_streaming_assets_folder);

到这里：

string full_path = string.Format("{0}/{1}",Application.streamingAssetsPath, path_with_extention_under_streaming_assets_folder);
