private void Page_Load(object sender, System.EventArgs e)
{
if (!IsPostBack)
{
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath("DataSource.xml"));
for(int i = 0;i <ds.Tables[0].Rows.Count ;i++)
{
DataRow dr = ds.Tables[0].Rows[i];
Want.Text += String.Format("Group[Groupcount++] = new Array(\"{0}\",\"{1}\",\"{2}\");\n", dr["v_Source"],dr["v_GroupName"].ToString(), dr["v_title"].ToString());
if (SourceList1.Items.FindByText(dr["v_Source"].ToString()) == null)
{
SourceList1.Items.Add(dr["v_Source"].ToString());
}
}
}
}

可以介绍一下 Want.Text += String.Format("Group[Groupcount++] = new Array(\"{0}\",\"{1}\",\"{2}\");\n", dr["v_Source"],dr["v_GroupName"].ToString(), dr["v_title"].ToString());

这句是什么意思吗？

谁可以帮我解答一下嘛
