效果如下图：

hidfShows.Value =ini.IniValue("Set", "Show");
string include = hidfShows.Value;//获取当前页展示列
if (string.IsNullOrEmpty(names)||all == null)
{
//请先点加载配置信息
return;
}
for (int i = 0; i < all.Length; i++)//遍历所有列
{
if (include.IndexOf("@" + all[i] + "@") == -1)//当前列中不包含分割出来的列时放在不显示框中
{
xListBox1.Items.Add(new ListItem(resources[all[i]].ToString(),all[i]));
}
}
string[] showNames = include.Split(',');
string newName=string.Empty;

{

}
}
