2sxc |通过使用 Javascript 方法修剪来删除文件路径 [英] 2sxc | removing file path by trimming w/ Javascript method

问题描述

我显示了以下文件路径:

I have the following file path displaying:

而且我只想显示文件名Doc1"(减去路径和扩展名).

And I want to display only file name 'Doc1' (minus path and extension).

我尝试了以下操作但未成功，如果您能进一步了解我做错了什么，我将不胜感激...

I have tried unsucessfully the following and would appreciate any further light you could share as to what I am doing wrong...

    @functions{
    public static string SplitWord(string text, int length)
    {
        string str = text;
        int n = str.LastIndexOf(".");
        string str1=str.Substring(n,str.LastIndexOf("/"));
        str1=str1.Substring(1,str1.Length);
        return str1;
    }
}
<ol>
    @foreach (var q in AsDynamic(App.Data["CatFilter"]))
    {
    <li class="sc-element faq-set faq-setOne" data-tags="@String.Join(",", ((List<DynamicEntity>)q.Categories).Select(a => AsDynamic(a).EntityId))">
        @q.Toolbar @Edit.Toolbar(actions: "edit,new", contentType: "CatFilter")
        <a class="faq-question" style="cursor: pointer">
            @if(!String.IsNullOrEmpty(q.LinkText))
            {
               SplitWord(@q.LinkText,@q.LinkText.Length);
            } else {
               SplitWord(@q.Link,@q.Link.Length);
            }
        </a>
    </li>
    }
</ol>

我也在 IF 条件下尝试了以下变体，但还是没有运气.

I have also tried variations of the following within the IF condition but again no luck.

,,,,@:var str = q.Link;
,,,,@:var n = str.lastIndexOf(".");
,,,,@:var str1=str.Substring(n,str.lastIndexOf("/"))
,,,,@:str1=str1.Substring(1,str1.Length);

谢谢，

推荐答案

您实际上只是以错误的方式使用 Substring.你可能想要

You're actually just using Substring the wrong way. You probably want

public static string SplitWord(string text, int length)
{
    int slash = text.LastIndexOf("/");
    int dot = text.LastIndexOf(".");
    return text.Substring(slash + 1, dot - slash);
}

试一试 - 可能需要对其中一个值进行另一个 +1 或 -1，但这应该可以解决问题.

Give it a try - might need another +1 or -1 on one of the values, but that should do the trick.
