Question

您好我正在尝试打印div集合。打印div集合时我只获取第一个值。这是我的程序。

namespace ConsoleApplication4
{
    class Program
    {
        [STAThread]
        public static void Main(string[] args)
        {
            Browser bi;
            bi = new IE(@"https://www.proptiger.com/gurgaon/sector-37c/ild-grand-501804");
            string BHK_Collection = string.Empty;
            string Total_Units_details = string.Empty;
            DivCollection collection = bi.Divs.Filter(Find.ByClass("projImgContBoxInfo ng-scope"));

             foreach (var Span in collection)
             {
                 if (Span.OuterText.Contains("Basic information"))
                 {
                     BHK_Collection = Span.OuterText.Replace("  Request a site visit", "").Replace("Basic information", "").Replace("This configuration is available from builder", "").Replace("2D 3D Video Tour", "").Replace("\r\n", "\n").Replace("Bedroom(s)", "Bedroom(s);").Replace("Bath(s)", "Bath(s);").Replace("Balconie(s)", "Balconie(s);").Replace("Price On Request", "Price On Request;").Replace("Servant Room", "Servant Room;").Replace("sq ft", "sq ft;").Replace("Cr*", "Cr;").Replace("Request a floor plan", "").Replace("(", "").Replace(")", "").Replace("− Builder Price", "").Replace("Lacs*", "Lacs;").TrimStart();
                     Total_Units_details = string.Join(" ", BHK_Collection.Split('\r', '\n')).Replace("    ", "").Replace("  ", " ").Replace(System.Environment.NewLine, " ").TrimStart();
                 }
             }

             Console.WriteLine(Total_Units_details);            
         }
     }
 }

实际输出是

2BHK+2T - 1,280 sq ft ;66.6 Lacs;5,200 / sq ft;2 Bedroom(s);2 Bath(s);4   Balconie(s);EMI -  54,995
2BHK+2T - 1,310 sq ft ; 68.1 Lacs;5,200 / sq ft;2 Bedroom(s);2 Bath(s);3 Balconie(s);EMI -  56,233
3BHK+3T – 1,790 sq ft; 88.6 Lacs;4,950 / sq ft; 3 Bedrooms;3 Baths; 3 Balconies;EMI - 74,400
3BHK+3T – 1,820 sq ft; 90.1 Lacs;4,950 / sq ft; 3 Bedrooms;3 Baths;;EMI - 74,400
3BHK+4T Study – 2,289 sq ft; 1.66 Cr;7,250 / sq ft; 3 Bedrooms;4 Baths; 5 Balconies;EMI - 1,40,377

但我的程序只打印一个值。非常感谢。

您不会追加到Total_Units_details，而是在循环中的每次迭代中分配一个新值。

您可以使用：

foreach (var Span in collection)
{
    if (Span.OuterText.Contains("Basic information"))
    {
        BHK_Collection = Span.OuterText.Replace("  Request a site visit", "").Replace("Basic information", "").Replace("This configuration is available from builder", "").Replace("2D 3D Video Tour", "").Replace("\r\n", "\n").Replace("Bedroom(s)", "Bedroom(s);").Replace("Bath(s)", "Bath(s);").Replace("Balconie(s)", "Balconie(s);").Replace("Price On Request", "Price On Request;").Replace("Servant Room", "Servant Room;").Replace("sq ft", "sq ft;").Replace("Cr*", "Cr;").Replace("Request a floor plan", "").Replace("(", "").Replace(")", "").Replace("− Builder Price", "").Replace("Lacs*", "Lacs;").TrimStart();
        //CHANGE HERE :
        Total_Units_details = Total_Units_details + Environment.NewLine + string.Join(" ", BHK_Collection.Split('\r', '\n')).Replace("    ", "").Replace("  ", " ").Replace(System.Environment.NewLine, " ").TrimStart();

    }
}

（字符串连接）：＆＃34;第一行＆＃34; + Environment.NewLine +＆＃34;第二行＆＃34 ;;

还尝试查找类StringBuilder它比使用上面的方法更好。您可以在循环的每次迭代中将新String附加到StringBuilder，然后追加Environment.NewLine

class Program
{
    [STAThread]
    public static void Main(string[] args)
    {
        Browser bi;
        bi = new IE(@"https://www.proptiger.com/gurgaon/sector-37c/ild-grand-501804");

        string BHK_Collection = string.Empty;

        string Total_Units_details = string.Empty;

        DivCollection collection = bi.Divs.Filter(Find.ByClass("projImgContBoxInfo ng-scope"));

        foreach (var Span in collection)
        {
            if (Span.OuterText.Contains("Basic information"))
            {
                BHK_Collection = Span.OuterText.Replace("  Request a site visit", "").Replace("Basic information", "").Replace("This configuration is available from builder", "").Replace("2D 3D Video Tour", "").Replace("\r\n", "\n").Replace("Bedroom(s)", "Bedroom(s);").Replace("Bath(s)", "Bath(s);").Replace("Balconie(s)", "Balconie(s);").Replace("Price On Request", "Price On Request;").Replace("Servant Room", "Servant Room;").Replace("sq ft", "sq ft;").Replace("Cr*", "Cr;").Replace("Request a floor plan", "").Replace("(", "").Replace(")", "").Replace("− Builder Price", "").Replace("Lacs*", "Lacs;").TrimStart();
                Total_Units_details = string.Join(" ", BHK_Collection.Split('\r', '\n')).Replace("    ", "").Replace("  ", " ").Replace(System.Environment.NewLine, " ").TrimStart();
            }
        }

        Console.WriteLine(Total_Units_details);            
    }
}

如果您想将每一行输出到控制台，则需要将Console.WriteLine移至foreach循环

foreach (var Span in collection)
{
    if (Span.OuterText.Contains("Basic information"))
    {
         BHK_Collection = Span.OuterText.Replace("  Request a site visit", "").Replace("Basic information", "").Replace("This configuration is available from builder", "").Replace("2D 3D Video Tour", "").Replace("\r\n", "\n").Replace("Bedroom(s)", "Bedroom(s);").Replace("Bath(s)", "Bath(s);").Replace("Balconie(s)", "Balconie(s);").Replace("Price On Request", "Price On Request;").Replace("Servant Room", "Servant Room;").Replace("sq ft", "sq ft;").Replace("Cr*", "Cr;").Replace("Request a floor plan", "").Replace("(", "").Replace(")", "").Replace("− Builder Price", "").Replace("Lacs*", "Lacs;").TrimStart();
         Total_Units_details = string.Join(" ", BHK_Collection.Split('\r', '\n')).Replace("    ", "").Replace("  ", " ").Replace(System.Environment.NewLine, " ").TrimStart();
         Console.WriteLine(Total_Units_details);
    }
}

div collection只打印一个值
