I was curious about how other people use the this keyword.我很好奇其他人如何使用this關鍵字。 I tend to use it in constructors, but I may also use it throughout the class in other methods.我傾向於在構造函數中使用它，但我也可能在整個類中的其他方法中使用它。 Some examples:一些例子：

In a constructor:在構造函數中：

public Light(Vector v)
{
    this.dir = new Vector(v);
}

Elsewhere別處

public void SomeMethod()
{
    Vector vec = new Vector();
    double d = (vec * vec) - (this.radius * this.radius);
}
