C# checkbox勾选输出

C#
checkbox1对应D:\1.txt
checkbox2对应D:\2.txt
checkbox3对应D:\3.txt

按下button1时 checkbox 中哪个被勾选
(假设勾选了1和2) 那就将1和2的内容保存到D:\4.txt

Answer 1

private void button1_Click(object sender, EventArgs e)
{
if (checkBox1.CheckState == CheckState.Checked &&checkBox2.CheckState == CheckState.Checked )
{
#region 保存数据到本地
if (File.Exists(@"D:\4.txt"))
{
//如果存在则删除
File.Delete(@"D:\4.txt");
}
StreamWriter sw = new StreamWriter(@"D:\4.txt", true, System.Text.Encoding.Default);
sw.Write("内容写到这里");
sw.Close();
}
} 大概是这样子
