C# ASP.net显示来自SQL的图像

解决方法：我使用了处理器。谢谢你。

如何在DataList1中显示图像？ 我对数据绑定之类的东西没有一个清晰的概念。我希望你们能帮忙。谢谢 这是我的ASPX代码

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1">
    <ItemTemplate>
        itemID:
        <asp:Label ID="itemIDLabel" runat="server" Text='<%# Eval("itemID") %>' />
        <br />
        Cloth ID:
        <asp:Label ID="Cloth_IDLabel" runat="server" Text='<%# Eval("[Cloth ID]") %>' />

Asp:Image.ImageUrl需要一个URL值，因此如果

Image1

是一个包含图像URL的字符串，则代码应该可以工作

---

相反，如果Image1是图像本身，那么您需要临时在服务器上为Asp:image控件提供保存文件的URL（检查是否生成URL）

如果您没有来自数据库的图像URL，并且sql中有图像数据类型，则此代码将有助于

如果图像路径存储在数据库中：~/Images/file-name.jpg

=>数据列表中的图像url：

ImageUrl='<%# Eval("[ImagePath]") %>' />

ImageUrl=''/>

什么数据类型是

image1

和

image2

？

ImageUrl='<%# Eval("[ImagePath]") %>' />
