从 MVC 视图中发布 2 个文件

如何从 MVC 视图将 2 个 Word 文档传递到控制器。

   @using (Html.BeginForm("UploadDocument", "Application", FormMethod.Post, new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <div class="form-group">
            <label for="file1">Please select application document (word file) </label>
            <input type="file" name="files" id="file1" class="form-control" />
            <label for="file2">Please select support document ( word file )</label>
            <input type="file" name="files" id="file2" class="form-control" />
        </div>
 }

在控制器中 

    public ActionResult UploadDocument(int Id, IEnumerable<HttpPostedFileBase> files)
    {
    }

但是我想在控制器内以不同的方式获取 file1 和 file2，以便我可以将其保存到不同的地方。我必须将文件1保存在一个地方，将文件2保存在另一个地方。那么如何确保我单独获取文件呢？

从 MVC 视图中发布 2 个文件

给它们一个单独的唯一名称：

@using (Html.BeginForm("UploadDocument", "Application", FormMethod.Post, new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <div class="form-group">
            <label for="file1">Please select application document (word file) </label>
            <input type="file" name="file1" id="file1" class="form-control" />
            <label for="file2">Please select support document ( word file )</label>
            <input type="file" name="file2" id="file2" class="form-control" />
        </div>
}

控制器：

public ActionResult UploadDocument(int Id, HttpPostedFileBase file1, HttpPostedFileBase file2)
{
    // do something with the files
}

更好的方法是将强类型视图与视图模型一起使用：

public class FileUploadViewModel {
    HttpPostedFileBase file1 { get; set; }
    HttpPostedFileBase file2 { get; set; }
}

视图：

@model MyProject.Models.FileUploadViewModel
@using (Html.BeginForm("UploadDocument", "Application", FormMethod.Post, new { enctype = "multipart/form-data" })) 
{
        @Html.ValidationSummary(true)
        <div class="form-group">
            <label for="file1">Please select application document (word file) </label>
            @Html.TextBoxFor(m => m.file1, null, new { type = "file", id = "file1", @class = "form-control" })
            <label for="file2">Please select support document ( word file )</label>
            @Html.TextBoxFor(m => m.file2, null, new { type = "file", id = "file2", @class = "form-control" })
        </div>
    }

控制器：

public ActionResult UploadDocument(int Id, FileUploadViewModel model)
{
    // do something with the files
    if(model.file1 != null && model.file1.ContentLength > 0) {
        // save first file
    }
    // etc.
}
