将表达式的值保存在文本框中 [英] save the value of expression in a textbox

问题描述

朋友们，

在下面的代码中，如何将expression的值(我在那里评论)保存到文本框中?
谢谢.

Hi friends,

in the code below how can I save the value of expression (I commented there) into a textbox?
Thanks.

public double bigzarb(double u,double v)
     {
         double n;
         double x=0;
         double y;
         double w=0;
         double z;
         string[] i = textBox7.Text.Split(',');
         int[] nums = new int[i.Length];
         for (int counter = 0; counter < i.Length; counter++)
         {
             nums[counter] = Convert.ToInt32(i[counter]);
         }
         u = nums[0];
         double firstdigits =Math.Floor(Math.Log10(u) + 1);
          v = nums[1];
         double seconddigits = Math.Floor(Math.Log10(v) + 1);
         if (firstdigits >= seconddigits)
         {
             n = firstdigits;
         }
         else
         {
             n = seconddigits;
         }
         if (u == 0 || v == 0)
         {
             MessageBox.Show("the Multiply is 0");
         }
         int intn = Convert.ToInt32(n);
         if (intn <=3)
         {
             double uv = u * v;
             string struv = uv.ToString();
             MessageBox.Show(struv);
             return uv;
         }
         else
         {
            int m  =Convert.ToInt32(Math.Floor(n / 2));
             x = u % Math.Pow(10,m);
             y = u / Math.Pow(10, m);
             w = v % Math.Pow(10,m);
             z = v / Math.Pow(10,m);
             return  bigzarb(x, w) *Math.Pow(10,m)+ (bigzarb(x,w)+bigzarb(w,y))*Math.Pow(10,m) +bigzarb(y,z);
///how can i show the value  of the line above in a textbox?
         }
     }

推荐答案

是您想要的吗?

Is that what you want?

double result = bigzarb(x, w) *Math.Pow(10,m)+ (bigzarb(x,w)+bigzarb(w,y))*Math.Pow(10,m) +bigzarb(y,z);
textBox1.Text = result.ToString()
return result;

尝试一下，

Try this,

textBox1.Text = bigzarb(1.0,2.0)

传递u和v值.

Pass the u and v value.
