这方面 C# 的属性(Property)语法是真的香。

**最传统的方式：**
private int _score = 10;

public int Score
{
get
{
// potential more logic here
return _score;
}
set
{
// potential more logic here
_score = value;
}
}

**简化方式（无默认值）**
public int Score { get; set; }

**简化方式（有默认值）**
public int Score { get; set;} = 10;

**简化方式只读属性**
public int Score { get; private set; }
public int Score { get; }

**简化方式只读属性带默认值**
public int Score => 10;
