如何在静态方法中引用非静态对象 [英] how to reference a non static object in a static method

问题描述

我创建了一个文本框，并希望在静态方法中引用它.我怎样才能做到这一点? 这是我的代码

I've created a textbox and want to reference it in a static methd. how can I do that? here;s my code

    private void Form1_Load(object sender, EventArgs e)
    {
        TextBox textbox2 = new TextBox();
        textbox2.Text = "A";
    }

    static void gettext() 
    {
        textbox2.Text = "B"; //here is my problem
    } 

推荐答案

您将需要以某种方式将其传递给静态方法，最简单的选择是仅扩展方法签名以接受文本框:

You would need to pass it into the static method somehow, easiest option is to just expand the method signature to accept the textbox:

static void gettext(TextBox textBox) 
{
    textBox.Text = "B"; //here is my problem
}
