无法获得正则表达式组值

Question

我要从中解析的字符串看起来像这样：

{ “F4q6i9xe”：{ “Hhgi79M1”： “cTZ3W2JG”， “j0Uszek2”： “0”}， “a3vSYuq2”：{ “Kn51uR4Y”：“c6QUklQzv + kRLnmvS0zsheqDsRCXbWFVpYhq2rsElKyFQnla01E6P3qQ26b + xWSrscFJCi2qsh6WjJKSW5FN9EwxRAWc3rfyToaEhRngI2WPu3W / B1 / hkkS2tEEk7LEpS2ItxLYKjEQGneO5E9rcGzbtfSOikdIjhxpD5m9HsKayo2ZSc2EYd / cN9yfYrNfLOCx + xeGqGcPmmImAzOZM0Q1IXIDQZ5r70vUS1aUOMOFnN1fVxmQ8ISofEKNEpHFfwWW9QUl9eVDgpQ2HES13s20kvVH2FOlE5uahIJBnyTLWYzViAWYyX13VK2PgrQcZ0oLuV84bSbjHGZf + JAjvImuyYhkKDhtTWAGkQ8LZ6r07duo71Gbz3glOUZZyz + FFiH5KrwafBpzGhRlI8El6lLZASN9Z5iZNTKs + sOti1fzsuOBzUXEjFURJGa93GMqPC + OyTw6YxKvgapz7go1XL7EAf50UXpMHd9xAJzsuIb6 / LB / 6V + XjD70wc74D2OosxtR6DIbQj3gbaBUBABQsJHQZLNnHWqikh + HLCASVbkqw6YPm5NecGaOQxonDkh3ZVQSF15WCEsgNdoWG94OuLF8DSw1t1Kt8sMFkvBJgB7LJS3pAw / TCG / rvR5qwZ / n31rtOzaJgCdVc6XeIK6Rttj4KvNtgtTwkJIjb97FgIS0CXrR0UCp3BsuLwQg3CRTnjQqsjGgJeinLXX2lq6vNOkxRzgXlWnap96kheYj7sIE / IxbJJWEIInMbH9HU / w0bS0MtIgofpIQAZ / m6XKhu9LpPZBgsBf9KX5chUPeuRfs3MfHFzPYPlCCd2dkE8BHKOTmfS3okqhkzIZvFN3Ni + 7enktFdgfpQ0toQbjhpn / TszP34pBaIy77me + GvePNO5bAFECLWSpGvsmW16rLCP0H + XIS /升 Nf9hK98jQqGU7eqpQdai7WFie2yN75Up7MrgBMp5w9Z5C7qpG2iYGiqynpqTCEnfQ3IZumbL + YvGTiuI2c320MGjKzOdO45MIU5fxUNZQSIfCSyIq5G / XGIeXCG3KETyKDZygXUTgEWbJWNTADE0AhXvP7HMtsuvstyuHvlTZGcfKS4oLnDPFiV1ndIV7 + W74Ytv9bAdDIVl36xTzA2PV6waqXBfSPUCTx3jVrAeXcHGFjZtxbk3pFmuqPqgVcxeX / aDbK0NHkR6phQcFEREBjfdCOLAAbCkWiRF0JAA ==“}}

这是我的正则表达式：

Hhgi79M1":"(?<encodeKeyID>.*?)",.*Kn51uR4Y":"(?<encodedBody>.*?)"}

这是我在C＃应用程序中使用的代码：

string responsePattern = "Hhgi79M1\":\"(?<encodeKeyID>.*?)\",.*Kn51uR4Y\":\"(?<encodedBody>.*?)\"}";
if (Regex.IsMatch(body, responsePattern))
{
    var match = Regex.Match(body, responsePattern);
    string encodeKeyID = match.Groups["encodeKeyID"].Value;
    string encodedBody = match.Groups["encodedBody"].Value;

现在可以正常工作，但是没有获取“ encodedBody”的值。 我用https://regex101.com/上的数据测试了我的表情，在那似乎效果很好。 但是，在程序中获取值时，它只是一个空字符串。

我感觉到问题在于您的正文字符串未正确转义，因为您的模式在以下代码中工作正常：

            string body = "{\"F4q6i9xe\":{\"Hhgi79M1\":\"cTZ3W2JG\",\"j0Uszek2\":\"0\"},\"a3vSYuq2\":{\"Kn51uR4Y\":\"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\"}}\n" +

尝试这种方式。

string sTarget = @"
