} 
}

} 
 <   / script  >  

解决方案

问题在于格式方法占位符（{0}，{1}）。你有6个参数，但编号为0,1,2,3,4,6 !!!

它应该是0到5 !!!

 <   table  >  <   thead  >  <   th     rowspan   =  6    width   =  150px >  <   img     runat   = 'Server'    src   = < b> {6}< / b> >  <   / img  >  < span class =code-keyword><   / th  >  <   / thead  >  <   / table  >  

this is error message??

Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

my code:

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        fillpage();
    }
    private void fillpage()
    {
        ArrayList comuterlist = connectionclass.getcomputertype(!IsPostBack ? "%" : DropDownList1.SelectedValue);
        StringBuilder sb = new StringBuilder();
        foreach (Cpmuter computer in comuterlist)
        {
            sb.Append(   //this error
                string.Format(
              @"<table class='computertable'>
<tr>

         <th rowspan='6' width='150px'><img runat='Server' src='{6}'></th>
         <th width='50px'>Name:</th>
         <td>{0}</td>
</tr>

<tr>

         <th>Type:</th>
         <td>{1}</td>
</tr>
<tr>

         <th>Processor:</th>
         <td>{2}</td>
</tr>
<tr>

         <th>Ram:</th>
         <td>{3}</td>
</tr>
<tr>

         <th>Price:</th>
         <td>{4}</td>
</tr>

</table>",
         computer.name, computer.price, computer.processor, computer.ram, computer.type, computer.image));
            lblout.Text = sb.ToString();
        }
    }

    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        fillpage();
    }
</script>

解决方案

The problem is with the Format method placeholders ({0}, {1}). You have 6 parameters but numbered them as 0,1,2,3,4,6!!!
It should be from 0 to 5!!!

<table><thead><th rowspan="6" width="150px"><img runat="'Server'" src="<b>{6}</b>"></img></th></thead></table>
