复选框if语句问题 [英] Checkbox if-statement problem

问题描述

if (sexch.Checked == true)
            {

                ch.Text = "male";
            }
           else  if (sexch.Checked == false)
            {
                ch.Text = "Female";

            }

当复选框==时我有这个代码我想要更改label.text对男性问题是该程序只读取其他内容。



我从数据库中获取sexch复选框，并根据数据库的输出（true = male，false = female）我要更改label.text 。



我的尝试：

I have this code when the checkbox ==true I want a label.text to change to male. The problem is that the program only read the else.

I am getting the sexch checkbox from a database and depending on the output(true=male, false=female) of the database I want to change the label.text.

What I have tried:

if (sexch.Checked == true)
            {

                ch.Text = "male";
            }
           else  if (sexch.Checked == false)
            {
                ch.Text = "Female";

            }

if (sexch.Checked == true)
            {

                ch.Text = "male";
            }
             if (sexch.Checked == false)
            {
                ch.Text = "Female";

            }

推荐答案

您的问题是您根本不需要第二个if语句。如果复选框不为true，则必须为false。

Your problem is that you don't need the second if statement at all. If the checkbox is not true, it must be false.

if (sexch.Checked == true)
{
    ch.Text = "Male";
}
else
{
    ch.Text = "Female";
}

使用 CheckBox.CheckedChanged事件（System.Windows.Forms） [ ^ ]



在其中，使用：

Use CheckBox.CheckedChanged Event (System.Windows.Forms)[^]

Inside of it, use:

ch.Text = sexch.Checked ? "Male" : "Female";

如果您想根据数据库值更改复选框状态：

In case you want to change checkbox state based on database value:

sexch.Checked = database_value;
