问题描述
这段代码不是我的 r 王,可以帮我看看这段代码需要添加一些东西吗?因为我的问题是如何检查xml文件中可用的ID是否为
protected void Button3_Click(object sender,EventArgs e)
{
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.Load(Server.MapPath(" Inventory.xml"));;
if(TextBox1.Text.Equals(""))
{
Label1.Visible = true;
Label1.Text =" Please write Id"; $
返回;
}
否则为
{
}
if(!System.IO.File.Exists(Server.MapPath(TextBox1.Text +" Inventory.xml"))))b
{
Label1.Visible = true;
Label1.Text =" ID available";
返回;
}
否则为
{
Label1.Visible = true;
Label1.Text ="使用的ID,请重写" ;;
TextBox1.Text ="" ;;
返回;
$
}
}
我的xml文件
