有没有任何好处的：

public class RemotingEngine
{
    uint m_currentValueId;
    object m_lock;

    public RemotingEngine()
    {
        m_currentValueId = 0;
        m_lock = new object();
    }

VS。这样的：

vs. this:

public class RemotingEngine
{
    uint m_currentValueId = 0;
    object m_lock = new object();

我一直回避第二个只是因为感觉脏。这显然​​是少打字，这样是吸引我。

I have been avoiding the second one just because it feels 'dirty'. It is obviously less typing so that is appealing to me.

推荐答案

它可以使在继承的情况有所不同。查看对象的初始化顺序此链接： http://www.csharp411.com/c-object-initialization/

It can make a difference in an inheritance situation. See this link on the object initialization order: http://www.csharp411.com/c-object-initialization/

因此​​，如果这是一个派生类中，整个基础对象时，你的派生字段被初始化和构造函数之间运行时初始化。

So if this is a derived class, the entire base object is initialized between when your derived field is initialized and when your constructor runs.
