umbraco string trim using razor view

Question

I have a Umbraco script Im using on a site, inside it there is a razor script as below:

<p>@page.GetProperty("mainContent")</p>

The above is in a loop, and shows content for each post (its being used on a landing page with blog like functionality)

I want to trim the content outputed by the GetPropery() method to say 300 charectors.

Anyone have any ideas?

Also, what word is the opposite of concatenate?

Answer 1

You could write a custom helper:

public static class HtmlExtensions
{
    public static string Truncate(this HtmlHelper html, string value, int count)
    {
        if (string.IsNullOrEmpty(value))
        {
            return string.Empty;
        }

        if (value.Length > count)
        {
            value = value.Substring(0, count - 1) + "...";
        }

        return value;
    }
}

which could be used like this:

<p>@Html.Truncate(page.GetProperty("mainContent"), 300)</p>
