news = Double.Parse(txtAmt.Text) + Double.Parse(txtOldSalary.Text);
txtNewSalary.Text = news.ToString();

推荐答案

您可以尝试一下..

You can try this..

Double news;
news = Convert.ToDouble(txtAmt.Text) + Convert.ToDouble(txtOldSalary.Text);
txtNewSalary.Text = news.ToString();

Double abc = Convert.ToDouble(TextBox1.Text.Trim()) + Convert.ToDouble(TextBox2.Text.Trim());


这有帮助吗?

Double abc = Convert.ToDouble(TextBox1.Text.Trim()) + Convert.ToDouble(TextBox2.Text.Trim());


Does that help?

双重新闻；
news = Convert.ToDouble(txtAmt.Text)+ Convert.ToDouble(txtOldSalary.Text);
txtNewSalary.Text = news.ToString();

Double news;
news=Convert.ToDouble(txtAmt.Text) + Convert.ToDouble(txtOldSalary.Text);
txtNewSalary.Text = news.ToString();
