如何在特定点拆分字符串并收集拆分中间的内容？

Question

假设我有一些示例文本

jordan went to the shop to buy some bread end

jordan sold some tomatos end

jordan went to see his father end

如果这是一个单独的字符串，我如何在单词 "Jordan" 和 "end" 处拆分此字符串以获取中间的文本并将其放入数组中？

我期望的输出是

string [] sArr = {
    "went to the shop to buy some bread",
    "sold some tomatos",
    "went to see his father"
}

Answer 1

尝试使用 Split() 方法：

String str = "jordan went to the...";
String[] separator = new String[] { "jordan", "end"};
String[] res = str.Split(separator, StringSplitOptions.RemoveEmptyEntries);

这将提供您正在寻找的输出。请记住，它还会保留 end 和 jordan 之间的任何文本。

好吧，你可以使用正则表达式来完成：

var s = "jordan went to the shop to buy some bread end jordan sold some tomatos end jordan went to see his father end";
var list = new List<string>();
foreach (Match match in Regex.Matches(s, @"jordan (.*?) end"))
{
    if(match.Success)
        list.Add(match.Groups[1].Value);
}

var sArr = list.ToArray();

或者用 LINQ 可以做得更优雅：

var sArr = Regex.Matches(s, @"jordan (.*?) end")
    .Cast<Match>()
    .Where(m => m.Success)
    .Select(m => m.Groups[1].Value)
    .ToArray();

如果需要，您可以将它们替换为空字符串。试试这个：

string str1 = "jordan went to the shop to buy some bread end";
        string str2 = "jordan sold some tomatos end";
        string str3 = "jordan went to see his father end";
        string total = str1 + str2 + str3;
        if ((total.Contains("jordan")==true) ||(total.Contains("end")) )
        {
            total = total.Replace("jordan", "");
            total = total.Replace("end", "");
        }
        Console.WriteLine(total);
