c# - 我无法调用其他方法

Question

我不确定我是否做得对，但是当我在运行时单击CalculateBttn_Click 按钮时，我试图让CalculateGrossPay 方法运行。但是，无论出于何种原因，我都会遇到不断变化的随机语法错误。我不会改变任何东西来实现这一点。我应该制定一个单独的方法来计算总工资。

private void CalculateBttn_Click(object sender, EventArgs e)
{  CalculateGrossPay(decimal hours, decimal rate);

    }




    private decimal CalculateGrossPay(decimal hours, decimal rate)
    {
        decimal result=0.00m;
        decimal standardHours= 0.00m;
        decimal overtimeHours=0.00m;



        if (hours > 40)
        {

            overtimeHours = (hours - 40) * ( (rate) * 1.5m);
            standardHours = 40 * rate;

            DisplayOutPut.Text = name+ NameTextBox.Text + ""; 

            DisplayOutPut.Text = "Gross Pay:" + result;
        }
        else
        {
            standardHours = hours * rate;
            DisplayOutPut.Text = "Hours:" + HoursTextBox.Text;
            DisplayOutPut.Text = "Rate:" + RateTextBox.Text;
        }
        result = standardHours + overtimeHours;
        return result; 

}

Answer 1

Methods in C# that specify parameters need to be called with Parameters. CalculateGrossPay defines 2 Parameters the hours and the rate as decimal values.

Therefore you need to call CalculateGrossPay with two decimal values as Parameters (see example).

Example:

CalculateGrossPay(10.1,0.4);

Answer 2

错误在于您调用该方法的方式。您应该调用您的方法，如下所示：

decimal hours = 1;
decimal rate = 5;

CalculateGrossPay(hours, rate);

hours 和 rate 的值可以硬编码，或者您可以从用户界面读取它们。
