How to limit string by words in asp.net

Tue, 27 Dec 2011 02:22:00 -0500

Limiting words from an asp.net string is basically two step process.

1.Find the total number of words in the string.This is important in the sense that it helps us to compare with the number of words actually required by user.

2.Find the product string by splitting (as a string array) the input string and concatenate it again based on number of words required.

 public int CountWords(string s)
    {
        int c = 0;
        for (int i = 1; i < s.Length; i++)
        {
            if (char.IsWhiteSpace(s[i - 1]) == true)
            {
                if (char.IsLetterOrDigit(s[i]) == true ||
                    char.IsPunctuation(s[i]))
                {
                    c++;
                }
            }
        }
        if (s.Length > 2)
        {
            c++;
        }
        return c;
    }

    public string LimitWords(string s,int num)
    {
        string p = "";
        int count = CountWords(s);
        if (num > count)
            return s;

        string[] words = s.Split();

        for (int i = 0; i < num; i++)
        {

            p += words[i]+" ";
            
        }

        return p;
    }

How to use the above code ?

So , suppose we have a sample string -

string s = "A quick brown fox jumps over the lazy dog" ;

And we now need to limit it to 5 words we can make it happen this way -

string result = LimitWords(s,5) ;

This will give us an output of "A quick brown fox jumps" , a 5 word string in result variable.

Fixing BlogEngine.Net For SEO Requirements

After the Panda updates the onsite seo has taken a front seat.The html suggestions that you see in your Google Webmaster Tools must be taken care of.

Talking about a blog engine.net based site we have some conditions that needs to be fixed

1.Remove unnecessary tagged pages from google index.
2.301 Redirect duplicate pages occured due to Case problem of IIS (Ex Mobile-Review.aspx & mobile-review.aspx)
3.Remove paged urls from index except the main category url.
4.Remove duplicate post url from index bearing date in url (eg - yyyy/mm/dd)
5.Adding Canonical tag to duplicate post pages.

Google webmaster suggests these sample urls have problem

/?tag=/32-mega-pixel-ericsson-phones
http://www.xx.com/post/2009/10/28/Dodge-Ram-1500-mpv-review.aspx

/category/aa-Review.aspx
/category/AA-review.aspx

/category/aa-Review.aspx?page=5
/category/AA-review.aspx?page=5

And this one is the fix that you can extend

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using BlogEngine.Core;
using BlogEngine.Core.Web.Controls;
using System.Text.RegularExpressions;

			aLogin.HRef = BlogEngine.Core.Utils.RelativeWebRoot + "login.aspx?logoff";
		}
		else
		{
			aLogin.HRef = BlogEngine.Core.Utils.RelativeWebRoot + "login.aspx";
			aLogin.InnerText = Resources.labels.login;
		}

        if (Request.QueryString.Count == 0 && Request.RawUrl.Replace("?","").EndsWith("/default.aspx",StringComparison.OrdinalIgnoreCase))
        {
            string query = Request.QueryString["theme"];
            string theme = !string.IsNullOrEmpty(query) ? query : BlogSettings.Instance.Theme;

            //Control.MapPath() 

            PostViewBase postView = (BlogEngine.Core.Web.Controls.PostViewBase)LoadControl(path);
            postView.ShowExcerpt = true;// BlogSettings.Instance.ShowDescriptionInPostList;
            //just set a temp post to show - for not getting error
            Post tmp = BlogEngine.Core.Post.Posts[0];
