问题描述

这里有任何语法问题。我已经看到了@ item.FileName的值。它是相同的



作为m images文件夹中的图像名称。当我试图硬编码它是工作。是否有



任何语法错误？图像位于解决方案的图像文件夹中



**查看代码**

is there any syntax issue here.I have seen the value of @item.FileName .It is the same

as the name of image in m images folder. When i tried to hard code it is working.Is there

any syntax error? The image is in image folder of the solution

**Code from View**

@foreach (var item in Model)
{
    var x = @item.FileName;
    <img src= " @Url.Content("~/Content/themes/base/images/@item.FileName") " /> 
}

**控制器操作方法**

**Controller Action Method**

public ActionResult Index()
{
    SelectionModel sel = new SelectionModel();

    List<SelectionModel> lissel = new List<SelectionModel>();
byte[] imagedata;

    //byte[] stream ;

    string sql = "select filename from filestore";

    OracleConnection con = new OracleConnection(ConStr);
    OracleCommand com = new OracleCommand(sql, con);

    try
    {
        con.Open();   //Opening a connection
    
        OracleDataReader dr;
        dr = com.ExecuteReader();
    
        while (dr.Read())
        { 
            sel.FileName = dr[0].ToString(); //Here i am getting filename from the database      
            lissel.Add(sel);                  
        }                             
    }
    catch (Exception ex)
    {
    }

    return View(lissel);
}

推荐答案

尝试更改控制器操作方法

try by making change in your controller action method

public ActionResult Index()
{
    SelectionModel sel = new SelectionModel();
 
    List<SelectionModel> lissel = new List<SelectionModel>();
byte[] imagedata;
 
    //byte[] stream ;

    string sql = "select filename from filestore";
 
    OracleConnection con = new OracleConnection(ConStr);
    OracleCommand com = new OracleCommand(sql, con);
 
    try
    {
        con.Open();   //Opening a connection
    
        OracleDataReader dr;
        dr = com.ExecuteReader();
    
        while (dr.Read())
        { 
            sel.FileName = "~/Content/themes/base/images/"+dr[0].ToString(); //Here i am getting filename from the database      
            lissel.Add(sel);                  
        }                             
    }
    catch (Exception ex)
    {
    }
 
    return View(lissel);
}

并且在视图中稍作改动

And make little bit change in view as

@foreach (var item in Model)
{
    <img src="@item.FileName" /> 
}

我找到了解决方案。我不知道如何在Url.Content中使用vairable 。解决方案是







< img src =@ Url.Content（〜/内容/主题/基础/图像/+ @ item.FileName）/>

I have found the solution .I didnt know how to use a vairable in Url.Content.The solution is



<img src= " @Url.Content("~/Content/themes/base/images/" + @item.FileName ) "/>
