如何生成按键呢？ [英] how to generate keypress even?

问题描述

private void textBox4_KeyPress(object sender, KeyPressEventArgs e)
{
    int ascii = Convert.ToInt16(e.KeyChar);

    if ((ascii >= 97 && ascii <= 122) || (ascii >= 65 && ascii <= 90) || (ascii == 8))
    {

        e.Handled = false;

    }

    else
    {

        e.Handled = true;

    }
}

我写了这段代码，但是如何自动生成这个事件？

I have written this code but how to generate automatically this event?

推荐答案

转到设计师视图并选择TextBox，按F4查看属性窗口

点击事件的ligtning图标

找到你的事件想要添加并双击它。
