asp.net mvc -如何在标签

本文关键字：img 标签 net mvc asp | 更新日期: 2023-09-27 17:50:28

我正在连接我的HTML字符串现在HTML来自我的DB也有一些图像存储在DB路径和字节…现在我想在html <img>标签中显示我的图像然后我将其写入doc文件

下面是我的代码: 

if (ds.Tables[4].Rows.Count > 0)
{
    DataTable Dt_4 = ds.Tables[4];
    foreach (DataRow item in Dt_4.Rows)
    {
        QuestionName += "<br style='page-break-before: always'> <br style='page-break-before: always'>";
        QuestionName += "<b><span style='text-decoration:underline'>Question :  </span>" + Dt_4.Rows[0]["Q_Num"].ToString() + "</b>";
                                
        QuestionName += "<b><span style='padding-left:20px;'>Marks :  </span>(" + item["Marks"].ToString() + ")</b>";
        QuestionName += item["QuestionName"].ToString();
        string imagePath = item["ImagePath"].ToString();
                               
        QuestionName += " <div><img src='" + imagePath + "' height='350' width='450'> </div> ";
                             
    }                      
}

当我在服务器上运行

时，图像显示正确，但当我从本地机器访问服务器时，它不显示有什么帮助吗?

asp.net mvc -如何在<img>标签

您可以将图像嵌入为Base64编码字符串，如下所示:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAM0AAAD
 NCAMAAAAsYgRbAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5c
 cllPAAAABJQTFRF3NSmzMewPxIG//ncJEJsldTou1jHgAAAARBJREFUeNrs2EEK
 gCAQBVDLuv+V20dE....." alt="beastie.png">
    string MakeImageSrcData(string filename)
    {
        byte[] filebytes = System.IO.File.ReadAllBytes(filename);
        return "data:image/png;base64," +Convert.ToBase64String(filebytes, Base64FormattingOptions.None);
    }
<img src="<%=MakeImageSrcData("c:'path'to'my.png") %>" />
