在c#String类中,它们隐藏了字符串类中所有方法的详细信息.例如,"ToLower"方法实现如下.

 /// <summary>
    /// Returns a copy of this string converted to lowercase.
    /// </summary>
    /// 
    /// <returns>
    /// A string in lowercase.
    /// </returns>
    /// <filterpriority>1</filterpriority><PermissionSet><IPermission class="System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Flags="UnmanagedCode"/></PermissionSet>
    [__DynamicallyInvokable]
    public string ToLower();

我怎么能这样做到我自己的班级？并从类的用户隐藏我的实现细节.
