问题描述

大家好，

我正在寻找KeyPress事件的代码.

Hi All,

I''m looking for code for a KeyPress event.

Can any help me or give me the code for KeyPress event for textbox?

推荐答案

public textbox1_KeyPress(object sender,KeyPressEventArgs e)
{
e.KeyChar=char.ToUpper(e.KeyChar);//converts the entered char to upper
}

如果要对按下的按键进行任何验证，则可以在keydown事件中进行验证，并将布尔值传递给keypress事件，根据布尔值可以执行所需的操作

希望对您有帮助！

if you want to do any validations of the pressed key,you can do it in keydown event and pass a boolean value to keypress event,based on the bool value you can perform the operation you need

Hope it helps!!

myEditBox.KeyPress += (sender, eventArgs) => {
  MessageBox.Show(
    "You can examime eventArgs to see what key is pressed and act accordingly (even cancel the press)");
};
