Question

c# winfrom。有4个 checkBox控件，如何判断只要选中，就把选中的checkbox的内容放一起显示出来？

Answer 1

this.checkBox1.CheckedChanged += new EventHandler(CheckedChanged);
this.checkBox2.CheckedChanged += new EventHandler(CheckedChanged);
this.checkBox3.CheckedChanged += new EventHandler(CheckedChanged);
this.checkBox4.CheckedChanged += new EventHandler(CheckedChanged);
//选中的CheckBox的文本
private string strCheckBoxText = null;
void CheckedChanged(object sender, EventArgs e)
{
strCheckBoxText = string.Empty;
if (checkBox1.Checked)
{
strCheckBoxText = checkBox1.Text + ",";
}
if (checkBox2.Checked)
{
strCheckBoxText += checkBox2.Text + ",";
}
if (checkBox3.Checked)
{
strCheckBoxText += checkBox3.Text + ",";
}
if (checkBox4.Checked)
{
strCheckBoxText += checkBox4.Text;
}
if (!string.IsNullOrEmpty(strCheckBoxText))
{
strCheckBoxText = strCheckBoxText.TrimEnd(',');
}
}
