namespace ImageEx
{
    public partial class UploadCrop : System.Web.UI.Page
    {
        String path = HttpContext.Current.Request.PhysicalApplicationPath + "images\\";
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        protected void btnUpload_Click(object sender, EventArgs e)
        {
            Boolean FileOK = false;
            Boolean FileSaved = false;
            {
                  Session["WorkingImage"] = Upload.FileName;
                String FileExtension = Path.GetExtension(Session["WorkingImage"].ToString()).ToLower();
                String[] allowedExtensions = { ".png", ".jpeg", ".jpg", ".gif" };
                for (int i = 0; i < allowedExtensions.Length; i++)
                {
                    if (FileExtension == allowedExtensions[i])
                    {
                        FileOK = true;
                    }
                }
            }

            if (FileOK)
            {
                try
                {
                    Upload.PostedFile.SaveAs(path + Session["WorkingImage"]);
                    FileSaved = true;
                }
                catch (Exception ex)
                {
                    LblError.Text = "File could not be uploaded." + ex.Message.ToString();
                    LblError.Visible = true;
                    FileSaved = false;
                }
            }
            else
            {
                LblError.Text = "Cannot accept files of this type.";
                LblError.Visible = true;
            }

            if (FileSaved)
            {
                pnlUpload.Visible = false;
                pnlCrop.Visible = true;
                imgCrop.ImageUrl = "images/" + Session["WorkingImage"].ToString();

            }


        }




    }
}

以上是我的代码隐藏文件

$（'

The above is my codebehind file
$('

< img src =

<img src=" "

'））

.css

{//一些代码





}

'))
.css
{//some code


}

推荐答案

（'

< img src =

<img src=" "

'））

.css

{ //一些代码





}

'))
.css
{//some code


}

对于图像src，指定完整的URL到图像文件。例如：http：//www.test.com/images/testimage.jpg。这将显示图像

For the image src specify the full url to the image file.For eg: http://www.test.com/images/testimage.jpg. This will display the image
