            wereErrors = true;

            if (fatal) app.Close();
        }

        public TextWriter ErrorStream
        {
            get;
            private set;
        }

        public TextWriter OutputStream
        {
            get;
            set;
        }

        bool wereErrors = false;

        string startTime;
        string errFile;
        string outFile;

        RenderWindow app; // SFML RenderWindow
    }
}

ErrorLog我在Main方法中创建了一个实例。但是，出于某种原因，即使创建了.logand文件，也没有任何内容被写入。.err我所看到的只是两个大小为 0 字节的空文件，其中没有写入任何文本。

你必须刷新你的流，即：

OutputStream.Flush();
