它只显示最后一次乘法 [英] its show only last multiplication

问题描述

protected void btngenaratetable_Click(object sender, EventArgs e)
       {
           int number = Convert.ToInt32(txtinputno.Text);
           int limit = Convert.ToInt32(txtlimit.Text);
           for (int x = 1; x <= limit; x++)
           {
               int result = number * x;
               string final = number + " * " + x + " = " + result+ "</br>";
               lblshowresult.Text = Convert.ToString(final);
           }

推荐答案

这里的问题是你要更新你的文本框lblshowresult.Texteveryvery，因为它只显示你的最后的结果。



如果修改代码如下：

issue here is you are updating your textbox lblshowresult.Textevery time because of which it get shows you only the last result.

If you modify the code like:

int number = 3;
           int limit = 3;
           for (int x = 1; x <= limit; x++)
           {
               int result = number * x;
               string final = number + " * " + x + " = " + result+ "</br>";
               //lblshowresult.Text = Convert.ToString(final);
            Console.WriteLine(final.ToString());
           }

你可以看到所有的结果。为了更好地看到你使用标签而不是文本框。



--SG

you can see all the result. in order to see the complete better you use label instead of textbox.

--SG

因为*的类型是字符串，但你不能直接将int转换为字符串

你必须转换为字符串。

because the type of * is string but you can not convert int to string directly
you must convert to string it .
