c# - Windows Phone将数据保存到文件

我尝试将数据保存到文件，但是收到以下错误Operation not permitted on IsolatedStorageFileStream行中的IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream(path, FileMode.OpenOrCreate, storage);

    public SaveFile(string path,string data)
    {
        var storage = IsolatedStorageFile.GetUserStoreForApplication();
        IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream(path, FileMode.OpenOrCreate, storage);
        StreamWriter writer = new StreamWriter(fileStream);
        writer.Write(data);
    }

最佳答案

试试这个:

public void SaveFile(string path, string data)
{
    using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
    {
        using (var fileStream = new IsolatedStorageFileStream(path + fileName, FileMode.Create, FileAccess.Write, storage))
        {
            using (StreamWriter writer = new StreamWriter(fileStream))
            {
                writer.WriteLine(data);
                writer.Close();
            }
            fileStream.Close();
        }
    }
}
