< blockquote> Koliber，
这意味着如果Dispose
方法的disposing参数为true，那么你想在任何引用上调用Dispose你有
实现IDisposable。假设你的班级有一个SqlConnection，它是b $ b持有的。如果处理参数为真，那么你会打电话给
处理连接，否则你不会。

Koliber，
这意味着如果Dispose
方法的处理参数为true，那么你想在你有的任何参考上调用Dispose
实现IDisposable。假设你的班级有一个SqlConnection，它是b $ b持有的。如果处理参数为真，那么你会打电话给
处理连接，否则，你不会。
否否否否
Net告诉我，SqlConnection是非托管资源（资源我需要管理的资源） - 你说
它是托管资源吗？如果是这样，什么是非管理资源？
K.
Koliber，
SqlConnection是一个托管资源。非托管
资源的一个示例是通过调用非托管代码或
a文件句柄，或套接字句柄或任何类型的指针或句柄获得的窗口句柄那个你不会被CLR管理的
。

sorry for my not perfect english
i am really f&*ckin angry
in this common pattern about dispose:
//////////////////////////////////////////////////////////
Public class MyClass:IDisposable
{
private bool IsDisposed=false;
public void Dispose()
{
Dispose(true);
GC.SupressFinalize(this);
}
protected void Dispose(bool Diposing)
{
if(!IsDisposed)
{
if(Disposing)
{
//Clean Up managed resources
}
//Clean up unmanaged resources
}
IsDisposed=true;
}
~MyClass()
{
Dispose(false);
}
}
////////////////////////////
most of things are clear -
there are two ways of calling dispose - one from finalizer (only
unmanaged managed will free automatically
if i do understand) second by Dispose() (managed and unamanaged by
hand) BUT
what the hell " //Clean Up managed resources " mean
pozdrawiam (greetings)

Koliber,
What this means is that if you the disposing parameter of the Dispose
method is true, then you want to call Dispose on any reference that you have
which implements IDisposable. Say your class had a SqlConnection that it
was holding onto. If the disposing parameter was true, then you would call
Dispose on the connection, otherwise, you would not.

No no no no
Net says to me that SqlConnection is unmanaged resource (resource I
should manage) - you say that
it is managed resource? If so what is unamanaged resource?
K.
Koliber,
SqlConnection is a managed resource. An example of an unmanaged
resource is a window handle that you obtained by calling unmanaged code, or
a file handle, or a socket handle, or any kind of pointer or handle that you
are holding onto which is not managed by the CLR.
