如何在按钮中调用布尔方法 [英] how to call boolean method in button

问题描述

public Boolean TFN()
    {
        Boolean tfn_status = false;
        if (txtTaxFileNumber.Text != null)
        {
            int sum = 0;
           
            string txtnumber = txtTaxFileNumber.Text;
            char[] nums = txtnumber.ToCharArray();
            int[] WEIGHT = new Int32[8] { 10, 7, 8, 4, 6, 3, 5, 1 };

            int val = 0;
            for (int i = 0; i < nums.Length; i++)
            {
                val += ((int)(nums[i])) * WEIGHT[i];
            }
            int remainder = val % 11;



            if (remainder == 0)
            {
                tfn_status = true;

            }

            else
            {
                tfn_status = false;
               
            }
           
        }
        return tfn_status;
    }

推荐答案

您不能立即将此函数作为事件调用，因为它不适合该格式...如果那样的话，这就是您要尝试做的.但是，如果您愿意，可以从实际事件中调用它.

You can''t call this function immediately as an event, because it doesn''t fit the format... If that''s what you''re trying to do. But, if you want, you could call it from the actual event.

我没有收到您的问题.

我想您正在寻找这个.

在button_click事件中

I am not getting your question.

I think you are looking for this.

in button_click event

button1_click(object sender,eventArgs e)
{
   Boolean blAns = TFN();
   if(blAns)
   {
      //to do for Yes
   }
   else
   {
      //to do for No
   }
}
