c# - 尝试反序列化时出现 System.Runtime.Serialization.SerializationException

Question

我有以下 json 字符串，我正在尝试反序列化

[{\"sha\":\"29a5ac11a67451d1b8bb6e525857cf35587334a2\",\"commit\":{\"author\":{\"name\":\"Christophe Coevoet\",\"email\":\"stof@notk.org\",\"date\":\"2013-03-06T08:53:13Z\"},\"committer\":{\"name\":\"Christophe Coevoet\",\"email\":\"stof@notk.org\",\"date\":\"2013-03-06T08:53:13Z\"},\"message\":\"Merge pull request #1071 from BrandonLWhite/master\n\nThis resolves Issue #1055\",\"tree\":{\"sha\":\"277ae283e984236883a18bf7e2c703abc17ce48a\",\"url\":\"https://api.github.com/repos/ComparetheMarket/chosen/git/trees/277ae283e984236883a18bf7e2c703abc17ce48a\"},\"url\":\"https://api.github.com/repos/ComparetheMarket/chosen/git/commits/29a5ac11a67451d1b8bb6e525857cf35587334a2\",\"comment_count\":0},\"url\":\"https://api.github.com/repos/ComparetheMarket/chosen/commits/29a5ac11a67451d1b8bb6e525857cf35587334a2\",\"html_url\":\"https://github.com/ComparetheMarket/chosen/commit/29a5ac11a67451d1b8bb6e525857cf35587334a2\",\"comments_url\":\"https://api.github.com/repos/ComparetheMarket/chosen/commits/29a5ac11a67451d1b8bb6e525857cf35587334a2/comments\",\"author\":{\"login\":\"stof\",\"id\":439401,\"avatar_url\":\"https://avatars.githubusercontent.com/u/439401?v=2\",\"gravatar_id\":\"7894bbdf1c05b18a1444ad8c76c9d583\",\"url\":\"https://api.github.com/users/stof\",\"html_url\":\"https://github.com/stof\",\"followers_url\":\"https://api.github.com/users/stof/followers\",\"following_url\":\"https://api.github.com/users/stof/following{/other_user}\",\"gists_url\":\"https://api.github.com/users/stof/gists{/gist_id}\",\"starred_url\":\"https://api.github.com/users/stof/starred{/owner}{/repo}\",\"subscriptions_url\":\"https://api.github.com/users/stof/subscriptions\",\"organizations_url\":\"https://api.github.com/users/stof/orgs\",\"repos_url\":\"https://api.github.com/users/stof/repos\",\"events_url\":\"https://api.github.com/users/stof/events{/privacy}\",\"received_events_url\":\"https://api.github.com/users/stof/received_events\",\"type\":\"User\",\"site_admin\":false},\"committer\":{\"login\":\"stof\",\"id\":439401,\"avatar_url\":\"https://avatars.githubusercontent.com/u/439401?v=2\",\"gravatar_id\":\"7894bbdf1c05b18a1444ad8c76c9d583\",\"url\":\"https://api.github.com/users/stof\",\"html_url\":\"https://github.com/stof\",\"followers_url\":\"https://api.github.com/users/stof/followers\",\"following_url\":\"https://api.github.com/users/stof/following{/other_user}\",\"gists_url\":\"https://api.github.com/users/stof/gists{/gist_id}\",\"starred_url\":\"https://api.github.com/users/stof/starred{/owner}{/repo}\",\"subscriptions_url\":\"https://api.github.com/users/stof/subscriptions\",\"organizations_url\":\"https://api.github.com/users/stof/orgs\",\"repos_url\":\"https://api.github.com/users/stof/repos\",\"events_url\":\"https://api.github.com/users/stof/events{/privacy}\",\"received_events_url\":\"https://api.github.com/users/stof/received_events\",\"type\":\"User\",\"site_admin\":false},\"parents\":[{\"sha\":\"70c46cfac7cb281af61d39f352d333eda9f1a84b\",\"url\":\"https://api.github.com/repos/ComparetheMarket/chosen/commits/70c46cfac7cb281af61d39f352d333eda9f1a84b\",\"html_url\":\"https://github.com/ComparetheMarket/chosen/commit/70c46cfac7cb281af61d39f352d333eda9f1a84b\"},{\"sha\":\"b1f85c040a4aca3cd3c1ec278264952eac7ea0f0\",\"url\":\"https://api.github.com/repos/ComparetheMarket/chosen/commits/b1f85c040a4aca3cd3c1ec278264952eac7ea0f0\",\"html_url\":\"https://github.com/ComparetheMarket/chosen/commit/b1f85c040a4aca3cd3c1ec278264952eac7ea0f0\"}]}]

使用这种反序列化方法

public List<RepositoryCommitData> DeserializeGithubCommitUrlJsonResponseAndTripUneededData(string json)
    {
        var serializer = new DataContractJsonSerializer(typeof (List<RepositoryCommitData>));
        var stream = new MemoryStream(Encoding.UTF8.GetBytes(json));
        var desirializedData = (List<RepositoryCommitData>) serializer.ReadObject(stream);

        return desirializedData;
    }

进入以下类(class)

[DataContract]
public class RepositoryCommitData
{
    [DataMember] public Committer commit;
}
[DataContract]
public class Committer
{
    [DataMember] public string name;
    [DataMember] public string date;
}

但我总是收到

System.Runtime.Serialization.SerializationException : There was an error deserializing the object of type System.Collections.Generic.List`1[[GitReport.Deserialization.RepositoryCommitData, GitReport, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]. Encountered invalid character ' '. ----> System.FormatException : Encountered invalid character ' '.

Answer 1

您的输入字符串中有两个 NEWLINE 字符(在输入文本中查找 \n)。如果您转义(或删除)这些，原始错误就会消失。 Here是反序列化前应转义的控制字符列表。

然后在您的原始 JSON 字符串中我收到了另一个错误，但是当您更新它时，我所要做的就是使用 \\n 转义 \n。
