想实现将表中字段的值绑定到对应的CheckBox,即：如果字段值为1，则对应CheckBox为选中状态；如果值为0，则对应CheckBox为非选中状态。我用以下方法可调试时，执行到powersView.Checked;
出错：CS0201: 只有 assignment、call、increment、decrement 和 new 对象表达式可用作语句
***.aspx.cs:
private void PowersBind()
{
string users_Name = userslist.SelectedItem.Text.ToString();
Users users = new Users();
DataRow dr = users.GetPowersLoad(users_Name);
if(dr!=null)
{
if (dr["powers_View"].ToString() == "1")
{
powersView.Checked; }
if (dr["powers_Add"].ToString() == "1")
{
powersAdd.Checked;
}
if (dr["powers_Modi"].ToString() == "1")
{
powersModi.Checked;
}
if (dr["powers_Del"].ToString() == "1")
{
powersDel.Checked;
}
if (dr["powers_Check"].ToString() == "1")
{
powersCheck.Checked;
}
}
}
