Question

我试图在MVC视图上显示ActiveDirectory用户的thumbnailPhoto属性。我将所需的属性解析为名为Employee的类的List：

for (int counter = 0; counter < resultCol.Count; counter++)
            {
                result = resultCol[counter];

                if (result.Properties.Contains("samaccountname") &&
                    result.Properties.Contains("displayname") &&
                    result.Properties.Contains("sn") &&
                    result.Properties.Contains("givenName"))
                {
                    list.Add(new Employee
                    {
                        Email = (String)result.Properties["samaccountname"][0],
                        FirstName = (String)result.Properties["givenName"][0],
                        LastName = (String)result.Properties["sn"][0],
                        pictureBLOB = result.Properties.Contains("thumbnailPhoto") ? (byte[])result.Properties["thumbnailPhoto"][0] : null,
                    });
                }
            }

我做了一些关于如何在索引视图上显示图片的研究，并发现这是一个可能的解决方案：

<div class="container">
@foreach (var item in Model)
{
    String imgSrc = String.Empty;
    String base64 = String.Empty;

    if (item.pictureBLOB != null)
    {
        base64 = Convert.ToBase64String(item.pictureBLOB);
        imgSrc = String.Format("data:image;base64,{0}", base64);

    }

    <div id="@Html.DisplayFor(i => item.Number)" class="col col-lg-2 col-md-4 col-sm-6">
        <a class="post" mailto="@item.Email" href="#">
            <img src="{@imgSrc}" title="@Html.DisplayFor(i => item.LastName), @Html.DisplayFor(i => item.FirstName)" />
            @*onerror="this.src = '../../Content/Images/nopicture.gif';" />*@
        </a>
    </div>
}
</div>

但是当我调用索引页面时，图片不会显示。是否有其他可能显示个人资料图片？

最后我找到了解决方案。我只需要删除

中@imgSrc周围的大括号

  <img src="{@imgSrc}" title="@Html.DisplayFor(i => item.LastName), @Html.DisplayFor(i => item.FirstName)" />

从byte []设置img src属性
