Thanks Rhys! how to write other code? (news.newsBodyText, 100) is not working

You'll need to either supply the appropriate Model or use .Value().

So, you could try something like:

foreach (News news in NewsList)

Where News is the name of your Model - this might be different for you.

In which case, your .Truncate() method would look like:

@Html.Truncate(news.NewsBodyText, 100)

To put it all together, your code could look something like:

@foreach (News news in NewsList)
{
    <div class="inner" style="width:100% !important">
        <div class="content">
            <header>
                <h3><a href="@news.Url">@news.Name</a></h3>
            </header>
            <div class="image fit">
                <img src="images/pic01.jpg" alt="" />
            </div>
            <p>
                @Html.Truncate(news.NewsBodyText, 100) 
            </p>
        </div>
    </div>
}
