New Snippet - Truncate your string with Razor helpers

Here's what i have done - using a helper to trim my string.

Here's the code:

@helper Truncate(string input, int length)
{
    if (input.Length <= length) {
        @input
    } else {
        @input.Substring(0, length)<text>...</text>
    }
}

@foreach(dynamic article in Model.Children)
{
 @article.siteTitle
 var bodyText = article.siteContent.ToString();
 @Truncate(bodyText, 20); @* ## YOU CAN COMBINE THIS WITH A MAC-PARAM..*@
}

Have fun dudes :)

If you add Html.Raw, then it also works when your string contains HTML tags. Bumped into this once... :)

@helperTruncate(stringinput,intlength)
{
    if(input.Length<=length){
        @Html.Raw(input)
    }else{
        @Html.Raw(input.Substring(0,length))<text>...</text>
    }
}
