如果单词比X长,则用点替换字符串的结尾

Question

如果它比X字符更长,我如何格式化Razor CSHTML页面中的字符串:

<p>@Model.Council</p> 

Example for an X = 9

-> if Council is "Lisbon", then the result is "<p>Lisbon</p>"
-> if Council is "Vila Real de Santo António", then the result is "<p>Vila Real...</p>" with the title over the <p> "Vila Real de Santo António" showing the complete information

谢谢.

Answer 1

任何字符串.看到这里.

而对于你的代码......

@(Model.Council.Length>10 ? Model.Council.Substring(0, 10)+"..." : Model.Council)

Answer 2

这是您可以使用的辅助方法:

public static class StringHelper
{
    //Truncates a string to be no longer than a certain length
    public static string TruncateWithEllipsis(string s, int length)
    {
        //there may be a more appropiate unicode character for this
        const string Ellipsis = "...";

        if (Ellipsis.Length > length)
            throw new ArgumentOutOfRangeException("length", length, "length must be at least as long as ellipsis.");

        if (s.Length > length)
            return s.Substring(0, length - Ellipsis.Length) + Ellipsis;
        else
            return s;
    }
}

只需从CSHTML中调用它:

<p>@StringHelper.TruncateWithEllipsis(Model.Council, 10)</p>
