Question

我需要Textbox来显示价格;小数点如：12,000,000 OR 1 000 (Price)
与MaskedTextBox我得到：120,000,00或100 0

如果有人能提供帮助，我会很高兴提前谢谢

Answer 1

您可以像这样使用DecimalFormat：

Double number = Double.valueOf(text);

DecimalFormat dec = new DecimalFormat("#.00 EUR");
String credits = dec.format(number);

TextView tt = (TextView) findViewById(R.id.creditsView);
tt.setText(credits);

Answer 2

 decimal a = 12000000;
        Console.WriteLine(a.ToString());
        //output=> 12000000

        Console.WriteLine(a.ToString("N"));
        //output=>12,000,000.00

        Console.WriteLine(a.ToString("N1"));
        //output=>12,000,000.0

        Console.WriteLine(a.ToString("N0"));
        //output=>12,000,000

尝试将此代码添加到KeyUp

的TextBox事件处理程序中

private void textBox1_KeyUp(object sender, KeyEventArgs e)
{
    if (!string.IsNullOrEmpty(textBox1.Text))
    {
        System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("en-US");
        int valueBefore = Int32.Parse(textBox1.Text, System.Globalization.NumberStyles.AllowThousands);
        textBox1.Text = String.Format(culture, "{0:N0}", valueBefore);
        textBox1.Select(textBox1.Text.Length, 0);
    }
}
