您面临什么问题?

按照看起来，您试图添加两个文本框的文本并在第三个文本框中显示它.您可以对同一事件使用各种事件.使用文本框的textchange事件进行加法，然后将其显示在第三位的操作.

What problem you are facing?

As per what it seems, you are trying to append texts of two textboxes and show it in third. You can use various events for the same. Use textchange event of the textboxes to do the operation of adding up and then displaying it in third.

这是答案-

公共button_click()
{
TextBox3.Text = Convert.ToInt32(TextBox1.Text)+ Convert.ToInt32(TextBox2.Text);
}

问候，

Here is answer -

public button_click()
{
TextBox3.Text = Convert.ToInt32(TextBox1.Text) + Convert.ToInt32(TextBox2.Text);
}

Hello Shanlu，

我已经使用C#来解决您的查询，因为您没有提及C#或VB.NET之类的任何标签，或者根据您的要求反正她的代码...

我觉得您是个初学者，所以请抢先阅读一本有关C#的好书并开始编码，
我首先将输入的文本转换为整数值，然后将其添加到第三个文本框中显示其结果

Hello Shanlu,

i have used C# to solve your query because u didn''t mention any tags like C# or VB.NET or something anyways hers your code as per your requirement...

I feel you are a beginner so grab a good book for C# and start coding,
i have first converted the text entered into integer value and then added them displaying their result at third textbox

private void button1_Click(object sender, EventArgs e)
        {
            //i have used try catch so that if the user tries characters a message will be displayed
            try
            {
                // adding two numbers here
               int x= int.Parse(textBox1.Text) + int.Parse(textBox2.Text);
                // display result in 3rd textbox
               textBox3.Text = x.ToString(); // integer is casted to string
            }
            catch (Exception ex)
            {
//show messagebox
                MessageBox.Show("Invalid text format for addition");
                //clear the textboxes
                textBox1.Clear();
                textBox2.Clear();
            }
        }
