推荐答案

第1步：



创建保存方法< br $>

step 1:

create save method

private void SaveData()
{
if(checkbox.Checked)
{
 //write save process codes 
} 

}

< br $>


第2步：



在复选框中调用save方法CheckedChanged事件

step 2:

call the save method in check box CheckedChanged event

private void checkBox_CheckedChanged(object sender, EventArgs e)
    {
       SaveData();
    }

首先，您需要决定保存哪个事件。更改检查或单击按钮时。然后你想把它保存到文件，数据库或其他地方。



假设它是一个按钮点击事件并保存到一个名为的文件和方法中SaveText（）：

你只需要在checkbox.Checked为true时进行测试

First you need to decide on what event will it be saved. Either when check changed or button was clicked. Then where/how you want to save it- to a file, database or other.

assume it is a button click event and saved to a file and method called is SaveText():
you only need to test for when checkbox.Checked is true

void SaveText()
{
   
string txt = textbox.Text;
if(checkbox.Checked){
// save to file
}
// else do nothing
}
