i new mvc, , have issue can't seem resolve. have seen several articles on similar issues, nothing can make fit bill need achieve.

i have mvc4 project, , need have multiple multi-file inputs on page, , need able distinguish between files submitted via input.

i have seen this article suggested having multiple post action args, code seems handle them single list.

here controller code :

public actionresult projectdocuments(c4tbl_uploadedfiles c4tbl_uploadedfiles, ienumerable<httppostedfilebase> file1, ienumerable<httppostedfilebase> file2)     {         try         {             foreach (var file in file1)             {                 if (file.contentlength > 0)                 {                    //handle first file list                 }             }             foreach (var file in file2)             {                 if (file.contentlength > 0)                 {                     //handle second file list                 }             } 

here view code :

    <table border="0" id="csstable" class="nobg">     <tr>         <th style="width: 100px; min-width: 100px; max-width: 100px">             <b>type</b>         </th>         <th style="width: 400px; min-width: 400px; max-width: 400px">             <b>file upload</b>         </th>         <th style="width: 500px; min-width: 500px; max-width: 500px">             <b>status</b>         </th>     </tr>     <tr>         <td style="width: 100px; min-width: 100px; max-width: 100px">             <b>blueprint(s)</b>         </td>         <td style="width: 400px; min-width: 400px; max-width: 400px">             <input type="file" name="file1" id="bp" multiple style="width: 380px"/>         </td>         <td style="width: 500px; min-width: 500px; max-width: 500px; text-align: left">             @html.radiobutton("submitted", "yes", false, new { @style = "width: 25px;", groupname="group1" }) uploaded                 @html.radiobutton("submitted", "no", false, new { @style = "width: 25px;", groupname="group1" }) not uploaded                 @html.radiobutton("submitted", "n/a", false, new { @style = "width: 25px;", groupname="group1" }) not applicable         </td>     </tr>     <tr>         <td style="width: 100px; min-width: 100px; max-width: 100px">             <b>recovery guide(s)</b>         </td>         <td style="width: 400px; min-width: 400px; max-width: 400px">             <input type="file" name="file2" id="rg" multiple style="width: 380px"/>         </td>         <td style="width: 500px; min-width: 500px; max-width: 500px; text-align: left">             @html.radiobutton("submitted", "yes", false, new { @style = "width: 25px;", groupname="group2" }) uploaded                 @html.radiobutton("submitted", "no", false, new { @style = "width: 25px;", groupname="group2" }) not uploaded                 @html.radiobutton("submitted", "n/a", false, new { @style = "width: 25px;", groupname="group2" }) not applicable         </td>         <td>             <input type="submit" value="submit" name="submit" />         </td>     </tr> </table>

this working controller code :

public actionresult projectdocuments(c4tbl_uploadedfiles c4tbl_uploadedfiles, ienumerable<httppostedfilebase> file1, ienumerable<httppostedfilebase> file2) {     try     {         foreach (var file in file1)         {             if (file.contentlength > 0)             {                //handle first file list             }         }         foreach (var file in file2)         {             if (file.contentlength > 0)             {                 //handle second file list             }         } 

this working view code :

<table border="0" id="csstable" class="nobg"> <tr>     <th style="width: 100px; min-width: 100px; max-width: 100px">         <b>type</b>     </th>     <th style="width: 400px; min-width: 400px; max-width: 400px">         <b>file upload</b>     </th>     <th style="width: 500px; min-width: 500px; max-width: 500px">         <b>status</b>     </th> </tr> <tr>     <td style="width: 100px; min-width: 100px; max-width: 100px">         <b>blueprint(s)</b>     </td>     <td style="width: 400px; min-width: 400px; max-width: 400px">         <input type="file" name="file1" id="bp" multiple style="width: 380px"/>     </td>     <td style="width: 500px; min-width: 500px; max-width: 500px; text-align: left">         @html.radiobutton("submitted", "yes", false, new { @style = "width: 25px;", groupname="group1" }) uploaded             @html.radiobutton("submitted", "no", false, new { @style = "width: 25px;", groupname="group1" }) not uploaded             @html.radiobutton("submitted", "n/a", false, new { @style = "width: 25px;", groupname="group1" }) not applicable     </td> </tr> <tr>     <td style="width: 100px; min-width: 100px; max-width: 100px">         <b>recovery guide(s)</b>     </td>     <td style="width: 400px; min-width: 400px; max-width: 400px">         <input type="file" name="file2" id="rg" multiple style="width: 380px"/>     </td>     <td style="width: 500px; min-width: 500px; max-width: 500px; text-align: left">         @html.radiobutton("submitted", "yes", false, new { @style = "width: 25px;", groupname="group2" }) uploaded             @html.radiobutton("submitted", "no", false, new { @style = "width: 25px;", groupname="group2" }) not uploaded             @html.radiobutton("submitted", "n/a", false, new { @style = "width: 25px;", groupname="group2" }) not applicable     </td>     <td>         <input type="submit" value="submit" name="submit" />     </td> </tr>
