c# - 构造函数重载和类参数

Question

有没有更好的方法来做我正在做的事情:

class Sample {

int SampleValueX, SampleValueY;
string SampleFacing;    

public Sample(int samplevaluex, string samplefacing)
{
    SampleValueX = startpositionx;
    SampleValueY = 0;
    SampleFacing = samplefacing;
}

public Sample(int samplevaluey, string samplefacing)
{
    SampleValueX = 0;
    SampleValueY = startpositionx;
    SampleFacing = samplefacing;
}
}

这甚至被称为构造函数重载吗？如果我错了，请纠正我。

Answer 1

可以使用可选参数

class Sample {

  int SampleValueX, SampleValueY;
  string SampleFacing;    

  public Sample(string samplefacing, int samplevaluex = 0, int samplevaluey = 0)
  {
    SampleValueX = samplevaluex;
    SampleValueY = samplevaluey;
    SampleFacing = samplefacing;
  }

}

注意可选参数必须出现在必选参数之后
