C#实例化和静态类对象调用对比

public string init = "实例化：hello";
public bool flag = false;
public int num = 0;
public void Test(string one)
{
    string test = "";

    if (!flag)
    {
        flag = true;

        num += 1;
        test = "【首次输出】" + init + one + num;
    }

    {
        num += 1;
        test = init + one + num;

    }
