提取DropDownList里的内容

for (i=1;i <=9;i++)
{
s[i] = this.DDL+i.SelectedValue;
t[i] = this.DDcommL+i.SelectedValue;
}
该怎么取值，谢谢！

[解决办法]
for (i=1;i <=9;i++)
{
s[i] = ((DropDownList)this.FindControl( "DDL " + i.ToString())).SelectedValue;
t[i] = ((DropDownList)this.FindControl( "DDLcomm " + i.ToString())).SelectedValue;
}
