我有一个这样的无序列表:

<div class="list">
<ul>
    <li>
        list1
        <ul>
            <li>Sub list1</li>
            <li>Sub list2</li>
            <li>Sub list3</li>
        </ul>
    </li>
    <li>
        list2
        <ul>
            <li>Sub list1</li>
            <li>Sub list2</li>
            <li>Sub list3</li>
        </ul>
    </li>
</ul>
</div>

我现在想要只为第一个列表应用CSS,而不是它的子ul和li.我尝试过以下方法:

.list ul li{
background:#ccc;
}

...但背景颜色应用于所有列表.应该怎么做才能改变只有父级而不是子级的CSS.

我参考了本教程并制作了自签名证书,并将https用于我的默认站点.但当我绑定https我的网站停止[ 图片下方 ]

当我尝试启动它时,它会显示出来

当我浏览到http://localhost那时它会打开iis8但是当我尝试打开https://localhost然后它会说

**The connection has timed out**

The server at localhost is taking too long to respond.

我有一个json对象是这样的:

{
    Yg7R_: {
    fld_invoice: "Yg7R_"
    fld_order_id: "5"
        fld_orders: {
            4: {
                fld_oiid: "4"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_H5epz2y4OB_IMG_20140326_020341.jpg"
                fld_loc: "../orders/oid_5/"
            }
        }
    }
    LldP_: {
    fld_invoice: "LldP_"
    fld_order_id: "7"
        fld_orders: {
            6: {
                fld_oiid: "6"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_SovH7Xf3n2_IMG_20140326_020418.jpg"
                fld_loc: "../orders/oids_7/"
            }
        }
    }
    NYEO: {
        fld_invoice: "NYEO"
        fld_order_id: "24"
        fld_orders: {
            27: {
                fld_oiid: "27"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_duLLsssVWA_IMG_20140326_020341.jpg"
                fld_loc: "orders/oid_24/"
            }
            28: {
                fld_oiid: "28"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_F8ayA4vWrP_IMG_20140326_020405.jpg"
                fld_loc: "orders/oid_24/"
            }
            29: { …

我有一个像这样的连接的查询:

string cmdString = "select tblPackages.*, tblPackageTypes.Name from tblPackages join tblPackageTypes on tblPackages.TypeId = tblPackageTypes.Id";

现在我使用这个SQL命令并返回像这样的datareader:

SqlCommand cmd = new SqlCommand(cmdString,con);
SqlDataReader dr;

我想将数据读取器的值填充到列表中.我提到了这个链接,但我得不到我需要的东西.

我有从sql输出的以下列

Id, TypeId, AllowedSMS, TimeSpan, Price, TypeName. 

我只是想在列表中传递它们.请帮助我..我是asp.net的新手

我正在尝试使用opencv3对四边形对象进行透视校正.我设法显示线条并使用HoughlinesImgproc.HoughLinesP()并试图突出显示使用的线条,Imgproc.lines()但输出没有成功.下面是我的代码,我也附加了输出图像.

请让我知道发生了什么错误以及应该做些什么......

Mat initImg; // initial image
Mat greyImg; // converted to grey

Mat lines = new Mat();
int threshold = 50;
int minLineSize = 20;
int lineGap = 10;

initImg = Imgcodecs.imread(imgLoc, 1);
greyImg = new Mat();
Imgproc.cvtColor(initImg, greyImg, Imgproc.COLOR_BGR2GRAY);
Bitmap bitm = Bitmap.createBitmap(greyImg.cols(), greyImg.rows(),Bitmap.Config.ARGB_8888);

Imgproc.blur(greyImg, greyImg, new Size(3.d, 3.d));
Imgproc.adaptiveThreshold(greyImg, greyImg, 255, Imgproc.ADAPTIVE_THRESH_MEAN_C, Imgproc.THRESH_BINARY_INV, 15, 4);

Imgproc.HoughLinesP(greyImg, lines, 1, Math.PI/180, threshold,
        minLineSize, lineGap);
// lines returns rows x columns and rows …

我有一个与jQuery模式对话框相关的小问题.场景是这样的:

当我通过按右上方的十字[x]按钮退出或关闭对话框时,我必须调用一个函数.
