C# - 使用正则表达式将数据排序到/从列表框

Question

我有一个包含数据的文件，我想将其分成三个不同的列表框。我希望第一个 ListBox 包含所有数据(从文本文档中读取的每一行数据都有一个新的列表项)。

主列表框:

D1
D2
C9
R7
R1
C130
D99
Q9

第二个 ListBox:(在使用正则表达式匹配以 D 开头的值之后)

D1
D2
D99

第三个列表框:(在使用正则表达式匹配以 C 开头的值之后)

C9
C130

在为 SECOND 和 THIRD 列表框匹配这些值后，

New Main ListBox 将如下所示:

R7
R1
Q9

问题

我目前有我的正则表达式，可以对文件进行排序并将文件分成三个单独的列表框。但是......我宁愿将数据放在其中一个列表框中，然后在匹配时从该列表框中排序/删除正确的正则表达式。

• 我如何将 .txt 文档加载到列表框中(每一个新行都是列表框中的一个新项目)，然后使用正则表达式遍历主列表框中的每一行以确定如果行进入不同的second 或third ListBox 或留在ma​​in ListBox？

Answer 1

您可以将它们组合成一个，而不是多个正则表达式。

您也不需要调用 Regex.Match其次是 match.Success ;只需调用 Regex.IsMatch .

我不明白你为什么要使用 result.Remove(line) .您从未添加过不匹配的行，那么为什么需要删除它？

最后，我认为您不需要使方法特定于使用 List<string> .您可以通过指定 IEnumerable<string> 使其更通用.

我重写了第一个来演示原理:

static IEnumerable<string> findPackagePlacementOneType(IEnumerable<string> list)
{
    return list.Where(line => Regex.IsMatch(line,
        @"^.+(RES|0402|0201|0603|0805|1206|1306|1608|3216|2551|1913|1313|2513" +
        @"|5125|2525|5619|3813|1508|6431|2512|1505|2208|1005|1010|2010|0505" +
        @"|0705|1020|1812|2225|5764|4532|1210|0816|0363|SOT)"
    ));
}

如果你真的需要一个新的 List<string> , 你可以只添加 .ToList()在调用 findPackagePlacementOneType 后.
