像 StreamWriter (Write, WriteLine) 一样使用 FileStream

Question

我想使用FileStream instead StreamWriter, because FileStream has .Flush(true) witch writes cached data on stream into disk, but when I changed StreamWriter to FileStream, there are many errors in my code, because FileStream没有.Write()和.WriteLine()方法

我如何使用 FileStreamLike StreamWriter? I want call .WriteLine(string _) on FileStream但它不存在。有没有办法添加这个方法？

可以通过extension这样的方法

    using System.IO;
    ...
    public static class MyExtensionClass
    {
        public static void Write(this FileStream fs, object value)
        {
            byte[] info = new UTF8Encoding(true).GetBytes(value + "");
            fs.Write(info, 0, info.Length);
        }
        public static void WriteLine(this FileStream fs, object value = null)
        {
            fs.Write(value + "\r\n");
        }
    }
