如果您确实想查找显式字符串，则 IndexOf< /a> 方法适合您（例如：s.IndexOf("ABC XYZ")）。

您显示的语法看起来有点像 field:"value" 语法，所以也许您想要一个像 "([az]+):\"([^"]+)\"" 这样的正则表达式（它应该匹配字段和成对的值）。

如果这不是你想要的，抱歉，但问题有点模糊。

至于模型和类别，您可以使用类似的方式捕获它们：

category:"([^"]*)"

这会搜索字符串 category:" ，后跟您的类别（假设可以更改，后跟另一个 "@"category:""([^""]*)"""。
类似地，您可以提取模型：Model:"([^"]*)"。

不确定其余的，但如果删除这两个，则留下自由字符串。

As for Model and Category, you can capture them using something like that:

category:"([^"]*)"

This searches for the string category:" followed by a your category (which assumbly can change, followed by another ". Of course, in c# this should be escaped: @"category:""([^""]*)""".
Similarity, you can extract the Model: Model:"([^"]*)".

Not sure about the rest, but if you remove these two, you are left with the free string.

看起来您想从同一个字符串中提取一些不同的模式。一
方法是找到每个匹配项，然后将其从工作字符串中删除。

示例：

String workingstring = "ABC XYZ category:\"Mobile Accessories\"";

Regex categoryMatch("category:\"([^\"]+)\"");
Regex modelMatch("model:\"([^\"]+)\"");

String category = categoryMatch.Match(workingstring);
String model = modelMatch.Match(workingstring);

workingstring = Regex.Replace(workingstring, categoryMatch, "");
workingstring = Regex.Replace(workingstring, modelMatch, "");

String name = workingstring; //I assume that the extra data is the name

无论字符串的格式如何，这都将提取类别、型号和名称。您应该注意格式错误的字符串，例如：

ABC Model:"Samsung 250" XYZ

将返回：

ABC  XYZ

It seems like you want to extract a few different patterns from the same string. One
approach would be to find each match and then remove it from your working string.

Example:

String workingstring = "ABC XYZ category:\"Mobile Accessories\"";

Regex categoryMatch("category:\"([^\"]+)\"");
Regex modelMatch("model:\"([^\"]+)\"");

String category = categoryMatch.Match(workingstring);
String model = modelMatch.Match(workingstring);

workingstring = Regex.Replace(workingstring, categoryMatch, "");
workingstring = Regex.Replace(workingstring, modelMatch, "");

String name = workingstring; //I assume that the extra data is the name

This will extract the Category, Model and Name regardless of the format of the string. You should note that malformed strings such as:
