C# 如何在Match.Regex中正确转义引号？

试验台：

输入字符串：_sql:SELECT*FROM AA 正则表达式：？：_sql[\s]*[^，]*

所需结果：从AA中选择*

现在我进入c并将其编码：

    Match match = Regex.Match("_sql\": \"SELECT * FROM AA", @"(?:""_sql""[\s]*)([^,]*)");
    if (match.Success)
    {
        String value = match.Groups[0].Value;
        Console.WriteLine(value);
    }

为什么match.Success为false？

您忘记在字符串周围加引号了

试一试-

您可以有一个单独的变量，并正确地转义它

string newVa = "\"_sql\": \"SELECT * FROM AA\"";
Match match = Regex.Match(newVa , @"(?:""_sql""[\s]*)([^,]*)");

或

string newVa = "\"_sql\": \"SELECT * FROM AA\"";
Match match = Regex.Match(newVa , @"(?:""_sql""[\s]*)([^,]*)");

Match match = Regex.Match(@"""_sql"": ""SELECT * FROM AA""", @"(?:""_sql""[\s]*)([^,]*)");
