我的情况是:
输入一个或多个字符后文本框的起始位置不允许有空格 文本框允许有空格
Not allowing spaces at starting position of textbox after enter one or more characters text box allows spaces
以下不适用于我的场景.
Below not applicable to my scenario.
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.Handled = (e.KeyChar == (char)Keys.Space))
{
MessageBox.Show("Spaces are not allowed");
}
}
textBox1.Text.TrimStart()
我相信lazyDBA的回答对你的要求是正确的,所以在消息框里面是这样的:
I believe that lazyDBA's answer is correct for your requirements, so with the message box something like:
if (textBox1.Text.Length == 0)
{
if (e.Handler = (e.KeyChar == (char)Keys.Space))
{
MessageBox.Show("space not allowed!");
}
}`
