问题描述

我注意到,在 System.Data.SQLite SQLiteConnection 对象拥有两个类似的方法:

I noticed that the SQLiteConnection object in System.Data.SQLite owns two similar methods :

  • 关闭()
  • 的Dispose()
  • Close()
  • Dispose()

同为 SQLiteDataReader 对象。

有什么区别?

推荐答案

处置也将关闭,如果它没有被关闭了连接,但打电话时关闭,您可以再次重新打开连接。这是不可能的,当连接配置。

Dispose also closes the connection if it hasn't been closed, but when calling Close, you can reopen the connection again. This is not possible when the connection is disposed.

在一般情况下,不叫关闭,而只是调用由包装建立在使用块:

In general, don't call Close, but simply call dispose implicitly by wrapping the creation of a connection in a using block:

using (var connection = new SqlConnection(...))
{
    // use connection here.
} // connection gets closed and disposed here.
