在文件夹中的网格中显示图像 [英] Displaying image in a grid from a folder

问题描述

我已经写了这样的代码....

I have written the code like this....

DataTable dt = new DataTable();
dt.Columns.Add("Image", typeof(string));
DataRow dr;
int i = 1;
foreach (string file in Directory.GetFiles(Server.MapPath(@"ImageUpload\")))
{
  //string nm = Path.GetFileName(file);
  dr = dt.NewRow();
  dr[0] = ResolveUrl(file);
  dt.Rows.Add(dr);
  i += 1;
}
grdimage.DataSource = dt;
grdimage.DataBind();

在这里，我的问题是图像没有显示在网格视图中.有人可以帮我吗?

Here, my problem is, that the image is not displayed in grid view. Can anyone please help me out?

推荐答案

只是因为您有图像路径并不意味着它将自动显示图像，所以您需要做一些工作.

您有一个包含Image控件的模板列，并将src属性从DataTable中绑定到Image列

Just because you have an image path doesn''t mean it will automatically display the image, you need to do a little work.

You have a template column that includes an Image control and you bind the src property to the Image column from your DataTable

选中此选项.

check this.

DataTable dt = new DataTable();
        dt.Columns.Add(new DataColumn("Image", typeof(string)));
        DataRow dr;
        int i = 0;
        foreach (string file in Directory.GetFiles(Server.MapPath(@"ImageUpload\")))
        {
            dr = dt.NewRow();
            dt.Rows.Add(dr);
            dr["Image"] = "ImageUpload/" + System.IO.Path.GetFileName(file);
            i += 1;
        }
        GridView1.DataSource = dt;
        GridView1.DataBind();

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
      <Columns>
          <asp:ImageField  DataImageUrlField="Image">
          </asp:ImageField>
      </Columns>
  </asp:GridView>
