推荐答案

您还可以缩短已经提供给此行的代码:

You could also shorten the code already presented to this single line:

TextBox1.Enabled = (!RadioButton1.Checked);

在Page_Load事件上，编写以下代码.

On Page_Load event , write the following code.

protected void Page_Load(object sender, System.EventArgs e)
{
    if (!IsPostBack) {
        TextBox1.Enabled = true;
    }
}

在RadioButton1_CheckedChanged事件上，编写以下代码.

On RadioButton1_CheckedChanged event, write the following code.

protected void RadioButton1_CheckedChanged(object sender, System.EventArgs e)
{
    if (RadioButton1.Checked) {
        TextBox1.Enabled = false;
    } else {
        TextBox1.Enabled = true;
    }
}

在表单加载时:

Textbox1.Enabled = False;

on Form Load:

Textbox1.Enabled=False;

private void radioButton1_CheckedChanged(object sender, EventArgs e)
        {
    if (Textbox1.Enabled==False)
       {Textbox1.Enabled=True;
       }
else
{Textbox1.Enabled=False;}
        }
