推荐答案

您可以将按钮ID传递给该函数.

You can pass the button id to the function.

void MyFunc(string buttonID)
{
    //insert function code here
}

private void btnSubmit_Click(object sender, EventArgs e)
{
    Button b = (Button)sender;
    MyFunc(b.Name);
}

您可以使用Button的CommandName属性来指定从哪个按钮引发事件. 每个按钮使用不同的命令名称.
希望这可以..

You can use CommandName property of Button to specify from which button the event has been raised..
use different command names for each button.
Hope this will work..

嘿，
您可以在函数中添加参数.并在调用函数时将按钮的名称作为参数发送.
例如

hey,
you can add an argument in the function. and send the name of the button as argument while calling the function.
e.g.

function Showdata(string buttonName)
{
if(buttonName=="btn1")
{
//do stuff
}
if(buttonName=="btn2")
{
//do stuff
}
}

if(buttonName=="btn3")
{
//do stuff
}

祝你好运
