List<generateCredentialsRoleList>无roleDescription/roleType定义问题求助

错误原因 #

你在初始化List<generateCredentialsRoleList>时搞错了对象层级：credentialsRoleList是一个List集合，不能直接给它设置roleDescription和roleType属性——这两个属性属于集合内的generateCredentialsRoleList实例，你需要先创建该类的对象，再把它添加到List中。

修正后的代码 #

public class generateTokenRequest
{
    public generateToken generateToken { get; set; }
}
public class generateToken
{
    public List<generateCredentialsRoleList> credentialsRoleList { get; set; }
    public string description { get; set; }
}

public class generateCredentialsRoleList
{
    public string roleDescription { get; set; }
    public string roleType { get; set; }
}

public string generateTokenRequest(string roleDescription, string roleType, string description)
{
    generateTokenRequest generateTokenRequest = new generateTokenRequest
    {
        generateToken = new generateToken
        {
            // 修正点：创建generateCredentialsRoleList实例并添加到List集合中
            credentialsRoleList = new List<generateCredentialsRoleList>
            {
                new generateCredentialsRoleList 
                {
                    roleDescription = roleDescription,
                    roleType = roleType
                }
            },
            description = description,
        }
    };
    string json = JsonConvert.SerializeObject(generateTokenRequest, Newtonsoft.Json.Formatting.Indented);
    return json;
}

补充说明 #

如果需要往List中添加多个角色实例，直接在集合初始化器里继续追加new generateCredentialsRoleList { ... }即可，多个实例用逗号分隔。
