If statements for Checkboxes
提问by user1512593
I wanted to know how to write if statements to see if one or another check box is checked or not.
我想知道如何编写 if 语句以查看是否选中了一个或另一个复选框。
I have two check boxes. I wanted it to check to see if checkbox 1 is checked and checkbox 2 is null then call this function, and if checkbox 2 is checked and checkbox 1 is null then call another function.
我有两个复选框。我想让它检查复选框 1 是否被选中并且复选框 2 为空然后调用这个函数，如果复选框 2 被选中并且复选框 1 为空然后调用另一个函数。
Pretty bad with IF statements and not sure how to convert the checkbox into a readable value.
IF 语句非常糟糕，并且不确定如何将复选框转换为可读值。

I'm making an assumption that you mean not checked. I don't have a C# compiler handy but:
我假设你的意思是没有检查。我手边没有 C# 编译器，但是：
if (checkbox1.Checked && !checkbox2.Checked)
{
}
else if (!checkbox1.Checked && checkbox2.Checked)
{
}

Your going to use the checkbox1.checkedproperty in your if statement, this returns true or false depending on weather it is checked or not.
您将checkbox1.checked在 if 语句中使用该属性，根据检查与否的天气返回 true 或 false。

In VB.Net
在 VB.Net 中
If Check1.checked and Not (Check2.checked) Then
ElseIf Check2.Checked and not Check1.Checked then
End If

I simplification for Science_Fiction's answer I think is to use the exclusive or function so you can just have:
我简化了 Science_Fiction 的答案，我认为是使用exclusive or 函数，这样您就可以拥有：
if(checkbox1.checked ^ checkbox2.checked)
{
//do stuff
}
That is assuming you want to do the same thing for both situations.
那是假设您想对两种情况都做同样的事情。

private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
if (checkBoxImage.Checked)
{
groupBoxImage.Show();
}
else if (!checkBoxImage.Checked)
{
groupBoxImage.Hide();
}
}
