配置处理工具类

一 调用wingdows API

  #region 使用WindowsAPI函数实现读写配置文件-固定写法
  [DllImport("kernel32", CharSet = CharSet.Unicode)]
  static extern long WritePrivateProfileString(string Section, string Key, string Value, string FilePath);
  [DllImport("kernel32", CharSet = CharSet.Unicode)]
  static extern int GetPrivateProfileString(string Section, string Key, string Default, StringBuilder RetVal, int Size, string FilePath);

  #endregion

 

 

二 实现配置文件的增删改查

        //读取
        public string Read(string Key, string Section = null)
        {
            var RetVal = new StringBuilder(255);
            GetPrivateProfileString(Section ?? EXE, Key, "", RetVal, 255, Path);
            return RetVal.ToString();
        }

        //写入
        public void Write(string Key, string Value, string Section = null)
        {
            WritePrivateProfileString(Section ?? EXE, Key, Value, Path);
        }

        //删除键
        public void DeleteKey(string Key, string Section = null)
        {
            Write(Key, null, Section ?? EXE);
        }

        //删除节点
        public void DeleteSection(string Section = null)
        {
            Write(null, null, Section ?? EXE);
        }

        //判断键是否存在
        public bool KeyExists(string Key, string Section = null)
        {
            return Read(Key, Section).Length > 0;
        }
