TextAsset返回null

Question

I have a script where I want to convert a text asset into a string array and then use that to modify PlayerPrefs. However, I keep getting a NullReferenceException Error during runtime on the second line in the code I have pasted below. I assume it's because I'm converting to the text asset into a string the wrong way. Could someone tell me what I'm doing wrong please? Thanks

            TextAsset txt = (TextAsset)Resources.Load("SaveKeys1", typeof(TextAsset));

        string txtString = txt.text;



        char sep = (',');
        string[] keys = txtString.Split(sep);

        foreach(string key in keys)
        {
            PlayerPrefs.DeleteKey(key);
            Debug.Log(key);
        }

The code:

TextAsset txt = (TextAsset)Resources.Load("SaveKeys1", typeof(TextAsset));
string txtString = txt.text;

is the correct way to do this. There is nothing wrong there and since you mentioned that the sceond line which is string txtString = txt.text; is causing an exception, there are two possible reasons for this.

1 .Your file name is not spelt correctly. Please copy the file name directly from where it is located and paste the name directly into the Resources.Load function. Make sure not to include the extension( .txt , .xml ...) in the function.

2 .The SaveKeys1 file does not have the right extension. TextAsset only supports file extensions like .txt , .html , .htm , .xml , .bytes , .json , .csv , .yaml , and .fnt

3 . SaveKeys1 file is not placed in the right folder. For the Resources.Load function to work, the file must be placed in a folder called Resources . Usually, placing this file in any folder called Resources should work but just for testing purposes, create the folder in the Assets/Resources directory then put your SaveKeys1 file there. This should work.
