推荐答案

您是否检查过您的应用是否具有访问系统文件的权限?另外，在使用 File.Exists(); 打开文件之前，我会检查一下文件是否存在.

Have you checked that your app has permission for accessing files on the system? Also i would to a check to see if the files exist before opening it with File.Exists();.

在 C# 中还有更好的读取和写入文件的方法:

Also there are better ways of reading and writing to files in C#:

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

using (var streamWriter = new StreamWriter(filename, true))
{
    streamWriter.WriteLine(DateTime.UtcNow);
}

using (var streamReader = new StreamReader(filename))
{
    string content = streamReader.ReadToEnd();
    System.Diagnostics.Debug.WriteLine(content);
}
