点击按钮后 要点很多次才能正确显示输出在textBox里的值,怎么回事?
public void button1_Click(object sender, EventArgs e)
{
// 贷款总数Check
if (m_lTotalMoney <= 0)
{
MessageBox.Show( "[贷款总数]输入不正确 ");
textBox1.Focus();
textBox1.Select(0, textBox1.Text.Length);
return;
}
m_lTotalMoney = long.Parse(textBox1.Text);
// 年利率Check
if (comboBox1.Text.Length == 0)
{
MessageBox.Show( "请输入[年利率] ");
comboBox1.Focus();
comboBox1.Select(0, comboBox1.Text.Length);
return;
}
// 获得月利率
if (m_dYearInterestRate <= 0)
{
MessageBox.Show( "[年利率]输入不正确 ");
comboBox1.Focus();
comboBox1.Select(0, comboBox1.Text.Length);
