Question

我为Android编写应用程序，需要将json写入.txt文件。 .txt文件位于项目根目录

现在我像这样解析json

string url2 = "http://new.murakami.ua/?mkapi=getProducts";
JsonValue json = await FetchAsync(url2);

private async Task<JsonValue> FetchAsync(string url)
{
    // Create an HTTP web request using the URL:
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(url));
    request.ContentType = "application/json";
    request.Method = "GET";

    // Send the request to the server and wait for the response:
    using (WebResponse response = await request.GetResponseAsync())
    {
        // Get a stream representation of the HTTP web response:
        using (Stream stream = response.GetResponseStream())
        {
            // Use this stream to build a JSON document object:
            JsonValue jsonDoc = await Task.Run(() => JsonObject.Load(stream));
            //dynamic data = JObject.Parse(jsonDoc[15].ToString);

            Console.Out.WriteLine("Response: {0}", jsonDoc.ToString());

            // Return the JSON document:
            return jsonDoc;
        }

我试着用这个：

StreamWriter sw = new StreamWriter(@"\myfile.txt");
sw.Write(json.ToString());
sw.Close();

但它说System.UnauthorizedAccessException: Access to the path "/\myfile.txt" is denied.

如何解析json到文件？

尝试更改应用程序私人目录的路径

string path = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
string filename = System.IO.Path.Combine(path, "myfile.txt");

using (var streamWriter = new StreamWriter(filename, true))
{
    //Write your data here
}

希望这有帮助
