c# 在类中将数据传递给窗体

在Form1中 textbox1的modifilers设为Public,

public static Form1 f=null;

public Form1()

{

InitializeComponent();

f = this;

}

private void button1_Click(object sender, EventArgs e)

{

test cl = new test();

cl.t_test();

}

类文件:

public class test

{

public void t_test()

{

Form1.f.textBox1.Text = "this is a test message!";

}

}
