Question

我有从JSON生成的类，如下所示：

[DataContract]
public class Issue
{
    [DataMember(Order = 0)]
    public string expand { get; set; }
    [DataMember(Order = 1)]
    public string id { get; set; }
    [DataMember(Order = 2)]
    public string self { get; set; }
    [DataMember(Order = 3)]
    public string key { get; set; }
}

[DataContract]
public class search
{
    [DataMember(Order = 0)]
    public string expand { get; set; }
    [DataMember(Order = 1)]
    public int startAt { get; set; }
    [DataMember(Order = 2)]
    public int maxResults { get; set; }
    [DataMember(Order = 3)]
    public int total { get; set; }
    [DataMember(Order = 4)]
    public IList<Issue> issues { get; set; }
}

我想访问＆＃34; id＆＃34;而且我试图像这样检索：

jiraIssues.IssueKey = item.issues.key ?? string.Empty;

收到错误＆＃34;不包含＆＃34;键＆＃34;的定义。请检查程序集参考

＆＃34;项目＆＃34;我好像在下面：

foreach (search item in issuesearched)
{
    JiraIssues jiraissues = new JiraIssues();
    SetIssueDetails(item, jiraissues, priorities, statuses, resolution, issuetypes);
}

有没有其他方法可以访问＆＃34; key＆＃34; ？我有什么问题，我出错了？

问题是一个列表所以你必须这样做：

s.issues [0]的.key;

（如果要设置第一个元素的键。不为其他元素设置键;）

其他样本：

public class Issue
{                          
    public string key { get; set; }
}


public class search
{
    public IList<Issue> issues { get; set; }
}

private static void Main(string[] args) {

    search s = new search();

    s.issues.Add(new Issue()); // YOU HAVE THREE ISSUES
    s.issues.Add(new Issue());
    s.issues.Add(new Issue());


    var x=s.issues[0].key; // YOU ACCESS 1st one
    x = s.issues[2].key; // YOU ACCESS 3rd one (zero based)


}

从类中获取JSON数据成员
