asp.net - asp.net - 请给我看一个dataview控件的find方法的例子

Question

我试图在 DataView 中找到但不能。如果有的话，请告诉我替代方案..

   string conString =  System.Configuration.ConfigurationManager.ConnectionStrings["aspDB"].ConnectionString;
    SqlConnection con = new SqlConnection(conString);
    SqlCommand cmd = new SqlCommand(cmdText:"select * from name", 
    connection: con);
    SqlDataAdapter adapter = new SqlDataAdapter(cmd);       
    DataSet ds = new DataSet("Customers");
    adapter.Fill(ds,"Customers");
    DataView dv;
    dv= new DataView(ds.Tables[0],"","id desc", DataViewRowState.CurrentRows);
   var find = dv.Find("abc");

    if (find == -1)
    {
        Response.Write("<script>alert('No Match')</script>");        
    }
    else 
    {
        Response.Write("<script>alert('Match Found')</script>");
    }
