Answer 1

但如果 还有另一类
 <tr>
                <td class="td1">
                生产
                  
                </td>
                <td class="td2">
                  <asp:TextBox ID="producenm" runat="server" TextMode="MultiLine"  Rows="3"  Width="80%"></asp:TextBox>
                
                </td>
                <td  class="td2"  style="width:350px;">
                <DIV style="HEIGHT: auto" class="MNtable">
             <TABLE style="WIDTH: 100%" id="myFile">
             <TBODY><TR><TD>
             <INPUT id="Button2" class="bt" onclick="javascript:addFile()" type="button" /> 
             <INPUT id="fjCnt" class="disNo" type="text" /></TD>
             </TR>
             <TR>
             <TD>
             <asp:Label id="saveStatu" runat="server" Text="" ForeColor="#990000"></asp:Label>
             </TD></TR></TBODY></TABLE></DIV>
                </td>
                
                </tr>
                
                 <tr>
                <td class="td1">
                品质
                  
                </td>
                <td class="td2">
                  <asp:TextBox ID="qualitynm" runat="server" TextMode="MultiLine"  Rows="3"  Width="80%"></asp:TextBox>
                
                </td>
                <td  class="td2"  style="width:350px;">
                <DIV style="HEIGHT: auto" class="MNtable">
             <TABLE style="WIDTH: 100%" id="myFile1">
             <TBODY><TR><TD>
             <INPUT id="Button1" class="bt" onclick="javascript:addFile1()" type="button" /> 
             <INPUT id="fjCnt1" class="disNo" type="text" /></TD>
             </TR>
             <TR>
             <TD>
             <asp:Label id="Label3" runat="server" Text="" ForeColor="#990000"></asp:Label>
             </TD></TR></TBODY></TABLE></DIV>
                </td>
                
                </tr>如果有两类要对应 的附件上传
前台可以 加上
function addFile1()
    {
    
     
        var oTb = document.getElementById("myFile1");
        var oTr = oTb.insertRow(0); 
          var fjCnt1 = document.getElementById("fjCnt1");
                 var name = "thefilename1" + fjCnt1.value;
        
       
        fjCnt1.value=parseInt(fjCnt1.value)+1;
        
       
        oTr.insertCell(0).innerHTML = "<input id='file1' name='"+name+"' type=file size='20'> <input type='button' value='取消' onclick='javascript:delObj(this)' class='imgButton'>";
    }但后台读的是file流就不知怎么区分上传的是生产的还是品质的附件了

Answer 2

Request.Files["表单名称"]来区分

Answer 3

想着用原来的代码,然后 读取第一分类的附件个数,
在个数里的就是第一分类然后读第二分类的个数
//把原文件名，现文件名，文件大小存到一个ArraList中
  ArrayList inls = new ArrayList();
  inls.Add(fileName);
  inls.Add(strRankName);
  inls.Add(filesize);  //保存文件增加到ArralList
  fileArr.Add(inls);上面的改成// 保存第一分类的                        if (iFile <Convert.ToInt16(fjnum.Text))
                        {                            inls.Add(fileName);
                            inls.Add(strRankName);
                            inls.Add(filesize);
                            inls.Add("sc");
                            fileArr.Add(inls);
                            
                        }

Answer 4

怎么区分上传的是生产的还是品质的附件了?
你的<input type=file name=xxx
不都是有name属性的吗？读取
生产的，你的name=shengchan1 name=shengchan2这样
品质的，你的name=pinzhi1 name=pinzhi2这样
