在 SQL-Server Compact Edition 3.5 中使用 Dispose() 方法
我在我的 C# 应用程序中使用 Microsoft 的 SQL-Server Compact Edition 3.5。 SqlCeConnection 将由自己的 Connection 类封装：
using System;
using System.Data.SqlServerCe;
class Connection
{
public Connection()
{
m_connection = new SqlCeConnection(connectionString);
}
public void Open()
{
m_connection.Open();
}
public void Close()
{
m_connection.Close();
}
private SqlCeConnection m_connection;
}
所以我的问题是：我是否必须调用 SqlCeConnection 实例的 Dispose() 方法，或者是否可以在我的类中实现 IDisposable 接口？斯特凡
I'm using Microsoft's SQL-Server Compact Edition 3.5 in my C# application. The SqlCeConnection will be encapsulated by an own Connection class:
using System;
using System.Data.SqlServerCe;
class Connection
{
public Connection()
{
m_connection = new SqlCeConnection(connectionString);
}
public void Open()
{
m_connection.Open();
}
public void Close()
{
m_connection.Close();
}
private SqlCeConnection m_connection;
}
So my Question is: Do I have to call the Dispose() method of the SqlCeConnection instance or may implement the IDisposable interface in my class?

鉴于您使用的是一次性对象，您必须确保在不再需要资源时调用其
Dispose方法。您有多种选择：您可以在自己的类的Close方法中调用Dispose，或者更好的是，您可以实现IDisposable。每当您的类存储需要处置的资源时，强烈建议实现
IDisposable。这将允许您的类的用户使用using模式或自行调用Dispose，确保始终尽快释放资源。查看正确实现 IDisposable
Given that you are using an object that is disposable, you have to make sure that you call its
Disposemethod when the resource is no longer needed. You have several choices: you could callDisposein theClosemethod of your own class, or, even better you could implementIDisposable.Implementing
IDisposableis highly recommended whenever your class stores resources that need disposing. This will allow users of your class to use theusingpattern or callDisposethemselves, ensuring that resources are always freed as soon as possible.Take a look at Implement IDisposable correctly
只需使用
using语句，因为它会自动调用指定对象上的 Dispose()。Just use the
usingstatement as it automatically calls the Dispose() on the specified object.
