Question

我在我的视图中上传图片的情况，然后应该填充模型中我的Components实体中的UploadedFile属性。但是，由于某种原因，从未达到过该物业。如果我输入一个名字，那就没问题了。我在这里错过了一些细节吗？

public partial class Components
{   
    public string Name { get; set; } // This gets set
    public HttpPostedFileBase UploadedFile { get; set; } // This doesn't gets set
    public byte[] Image { get { return ConvertToByte(UploadedFile); } set { ; } }

    public byte[] ConvertToByte(HttpPostedFileBase uploadedFile)
    {
        MemoryStream ms = new MemoryStream();
        uploadedFile.InputStream.CopyTo(ms);
        byte[] imageBytes = ms.ToArray();

        return imageBytes;
    }
}

使用文件上传查看：

@model EmbeddedStock.Models.ComponentViewModel

     div class="form-group">
        <div class="col-md-10">
            @Html.LabelFor(model => model.ComponentModel.Image, htmlAttributes: new {@class = "control-label col-md-2"})
            <a class="btn" href="javascript:;">
                Choose File...
                <input type="file" name="UploadedFile" Size="40" style="position: absolute; z-index: 2; top: 0; left: 0; filter: alpha(opacity=0); opacity: 0; background-color: transparent; color: transparent"
                       onchange='$("#upload-file-info").html($(this).val());'/>
            </a>
            <span class="label label-info" id="upload-file-info"></span>
        </div>
    </div>

ComponentViewModel：

public class ComponentViewModel
{
    public Components ComponentModel { get; set; }
}

根据Stephen Muecke的建议，更改名称＆＃39;在视图的输入字段中完成了这项工作。

<div class="form-group">
    <div class="col-md-10">
        @Html.LabelFor(model => model.ComponentModel.Image, htmlAttributes: new {@class = "control-label col-md-2"})
        <a class="btn" href="javascript:;">
            Choose File...
            <input type="file" name="ComponentModel.UploadedFile" Size="40" style="position: absolute; z-index: 2; top: 0; left: 0; filter: alpha(opacity=0); opacity: 0; background-color: transparent; color: transparent"
                   onchange='$("#upload-file-info").html($(this).val());'/>
        </a>
        <span class="label label-info" id="upload-file-info"></span>
    </div>
</div>
