Question

我开始学习ASP.NET Core MVC，我对将图像存储到数据库有一些疑问。到目前为止，我的代码就在这里。

DetailModel

@model LibaryManagmentSystems.Models.Catalog.AssetDetailModel

<div class ="container">
    <div class="page-header clearfix detailHeading"></div>
    <h2 class="text-muted">View Libary Item </h2>
</div>

<div class="jumbotron">
    <div class="row">
        <div class="col-md-4">
            <div>
                <img class="detailImage" src="@Model.ImageURL" />
            </div>
        </div>
        <div class="col-md-4">
            <div>
                <p id="itemTitle">@Model.Title</p>
                <p id="itemAuthor">@Model.AuthorOrDirector</p>
                <p id="itemStatus">@Model.Status</p>
                <p id="itemType">@Model.Type</p>
                <p id="itemLocation">@Model.CurrentLocation</p>

                @if (Model.Status == "Lost")
                  {
            <p>This item has been lost. It cannot be checked out</p>
            <p><a class="btn btn-lg btn-danger" role="button" asp-controller="Catalog" asp-action="MarkFound" asp-route-id="@Model.AssetID">Mark Item Found</a></p>


                 }

                @if (Model.Status == "Checked OUt")
                {
            <p id="itemPatron">Checked Out by: @Model.PatronName</p>
            <p><a class="btn btn-lg btn-success" role="button" asp-controller="Catalog" asp-action="CheckIn" asp-route-id="@Model.AssetID">Check In</a></p>
            <p><a class="btn btn-lg btn-warning" role="button" asp-controller="Catalog" asp-action="Hold" asp-route-id="@Model.AssetID">Place Hold</a></p>


                }

                @if (Model.Status == "Available")
                 {
            <p><a class="btn btn-lg btn-info" role="button" asp-controller="Catalog" asp-action="Checkout" asp-route-id="@Model.AssetID">Check Out</a></p>
                  }

            </div>
            <div class="col-md-4 detailInfo">
                <table>
                    <tr>
                        <td class="itemLabel">ISBN:</td>
                        <td class="itemValue">@Model.ISBN</td>
                    </tr>
                    <tr>
                        <td class="itemLabel">Call Number:</td>
                        <td class="itemValue">@Model.DeweyCallNumber</td>
                    </tr>
                    <tr>
                        <td class="itemLabel">Replacement Cost:</td>
                        <td class="itemValue">@Model.Cost</td>
                    </tr>
                </table>
            </div>
        </div>
    </div>
</div>

Detail.cshtml

@model LibaryManagmentSystems.Models.Catalog.AssetIndexModel


<div id="assets">
    <h3>Libary Catalog</h3>
    <div id="assetsTable">
        <table class="table table-condensed" id="catalogIndexTable">
            <thead>
                <tr>
                    <th>Image</th>
                    <th>Title</th>
                    <th>Author / Director</th>
                    <th>Dew Call Number</th>
                </tr>
            </thead>
            <tbody>
                @foreach (var asset in Model.Assets)
        {
            <tr class="assetRow">
                <td class=""> 
                    <a asp-controller="Catalog" asp-action="Detail" asp-route-id="@asset.Id">
                        <img src="@asset.ImageUrl" class="imageCell" />
                    </a>
                </td>
                <td class="">@asset.Title</td>
                <td class="">@asset.AuthorOrDirector</td>
                <td class="">@asset.DeweyCallNumber</td>
        </tr>
}
            </tbody>
        </table>
</div>
    </div>

在数据库中我创建了一个fild调用它的ImageURL，我将文件存储在文件夹目录和图像文件夹中，保存到C：\ Desktop \ LMS \ images \ emma.jpg

Image 1

当我运行应用程序时，我会得到那样的照片

Image 2

到目前为止有什么帮助吗？

Index.cshtml

writer = pd.ExcelWriter('test.xlsx',engine='openpyxl')
df.to_excel(writer,sheet_name='test2',startcol=10,startrow=20)
writer.save()

Answer 1

问题在于wwwrote文件中的.css文件。我删除它并再次创建它的工作原理。并在wwwroot / images目录中插入图像，它将起作用

body {
    padding-top: 50px;
    padding-bottom: 20px;
}

/* Wrapping element */
/* Set some basic padding to keep content from hitting the edges */
.body-content {
    padding-left: 15px;
    padding-right: 15px;
}

/* Carousel */
.carousel-caption p {
    font-size: 20px;
    line-height: 1.4;
}

/* Make .svg files in the carousel display properly in older browsers */
.carousel-inner .item img[src$=".svg"] {
    width: 100%;
}

/* QR code generator */
#qrCode {
    margin: 15px;
}

/* Hide/rearrange for smaller screens */
@media screen and (max-width: 767px) {
    /* Hide captions */
    .carousel-caption {
        display: none;
    }
}
