我需要帮助。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。

这是我到目前为止做的事情。

  

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);

所有人都无法工作。我的logcat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;
}

答案 0 :(得分:1)

我通过改变找到了解决方案:

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

到此:

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