-_-#楼主不会是说这样的吧

string myText = textBox1.Text;

[zelong77]

就是这个```
不过我是在点击事件里获取```
不在一个类不知道怎么弄了`````呵呵```
刚刚学`````

那也没什么不同，直接这样就行了

private void button2_Click(object sender, EventArgs e)
{
　　string myText = textBox1.Text;
}

如果通过点击按钮后得到的字符串，还要在别的地方用到，可以用一个全局变量来保存

string myText = "";
private void button2_Click(object sender, EventArgs e)
{
　　myText = textBox1.Text;
}
